OA Symptoms

  • May develop suddenly or very slowly
  • Arthritis can cause pain and stiffness
  • Some types of arthritis may cause swelling
  • Simple tasks may be difficult to do

Rheumatoid Arthritis, Post-traumatic Arthritis, Avascular Necrosis, Paget’s Disease

  • Rheumatoid Arthritis – Membranes or tissues lining the joint become inflamed
  • Post-traumatic Arthritis – Irregularities lead to more wear on the joint
  • Avascular Necrosis – Bone may collapse and damage the cartilage
  • Paget’s Disease – The density and the shape of the bone change
Rheumatoid Arthritis

Rheumatoid Arthritis

Did you know?

Rheumatoid arthritis, the most crippling form of arthritis, affects approximately 2.1 million Americans and two to three times more women than men. Further, the average onset for rheumatoid arthritis is between the ages of 20 and 45 years old.

Joint Degeneration
Pain from arthritis and joint degeneration can:

  • Be constant
  • Come and go
  • Occur with movement
  • Occur after a period of motionlessness
  • Be located in one spot
  • Be located in many parts of the body
  • Be worse during certain times of the day
  • Be worse after certain activities

Preparing for Your Doctor’s Visit

The Orthopaedic Evaluation

  • A thorough medical history
  • A physical examination
  • X-Rays
  • Additional tests, as needed

Medical History
A thorough medical history includes:

  • A list of all medications you are currently taking
  • Information on prior surgeries and/or treatments
  • Prior diagnoses
  • Family history

The information that the surgeon gathers during the medical history usually suggests the possibility of several different diagnoses.

Physical Examination
The physical examination enables your surgeon to evaluate important aspects of your joints, including:

  • Size and length
  • Strength
  • Range of motion
  • Swelling
  • Reflexes
  • Skin condition

X-Ray Evaluation
X-Rays help show how much joint damage or deformity exists. An abnormal X-ray may reveal:

  • Narrowing of the joint space
  • Cysts in the bone
  • Spurs on the edge of the bone
  • Areas of bony thickening called sclerosis
  • Deformity or incorrect alignment

Additional Diagnostic Tests
Occasionally, additional tests may be needed to confirm the diagnosis. These may include:

  • Blood tests
  • Urine analysis
  • Analysis of joint fluid
  • Magnetic Resonance Imaging (MRI)
  • Bone scan

Treatment Options

  • Medication
  • Physical therapy
  • Arthroscopy – cleaning the joint
  • Joint fluid supplements (injections that provide temporary pain relief)
  • Partial joint replacement
  • Total joint replacement


  • Aspirin-free pain relievers–acetaminophen
  • Nonsteroidal anti-inflammatories (NSAIDs)
  • Corticosteroids–injection/pill form

Physical Therapy

  • Passive range-of-motion exercises may help:
    – Reduce stiffness
    – Keep joints flexible
  • Isometric exercises help build muscle strength


What is arthroscopy?
Arthroscopy is a surgical procedure used to visualize, diagnose and treat problems inside a joint.

In an arthroscopic examination, an orthopaedic surgeon makes a small incision in the patient’s skin and then inserts pencil-sized instruments that contain a small lens and lighting system to magnify and illuminate the structures inside the joint.

During an arthroscopy, loose, pieces, damaged cartilage and inflammation can be wash out.  Occasionally procedures to stimulate cartilage growth can be performed.  An arthroscopy cannot cure arthritis but may decrease pain and slow progression.

Joint Fluid Supplements

Injections that provide temporary relief:

  • For patients whose joint pain does not improve with medication or physical therapy, “joint grease” injections may provide temporary relief. The joint is injected with a joint fluid supplement that acts as a lubricant for the damaged joint.
  • Joint injection schedules and duration of relief vary according to the treatment chosen and the individual patient. However, these injections do not cure the diseased knee, and joint replacement may be needed as the joint worsens with time.

Partial Joint Replacement

Partial joint replacement is a surgical procedure in which only the damaged or diseased surfaces of the joint are replaced, leaving much of the natural bone and soft tissue in place.

Total Joint Replacement

Total joint replacement is a surgical procedure in which certain parts of an arthritic or damaged joint are removed and replaced with a plastic or metal device or an artificial joint. The artificial joint is designed to move just like a healthy joint.

Joint Replacement

Joint replacement is a treatment option when pain:

  • Is severe
  • Interferes with daily activities
  • Interferes with work

Joint replacement is a decision that should include:

  • You
  • Your primary care provider
  • Your orthopaedic surgeon

Did you know?
Total joint replacements of the hip and knee have been performed since the 1960s. Today, these procedures have been found to result in significant restoration of function and reduction of pain in 90% to 95% of patients.

Joint Replacement Preoperative

Preparing for a joint replacement procedure begins weeks before the actual day of surgery.
In general, patients may need:

  • Routine blood tests
  • Urinalysis
  • Physical examination
  • Exercise
  • Quit smoking
  • Stop certain medications
  • Donate blood

Joint Replacement Preoperative

  • A general physical examination
  • Dental procedures
  • Skin condition
  • Smoking
  • Weight
  • Medications

When will I be able to go back to a normal daily routine?

This is a decision only you and your surgeon can make. Every patient’s experience is different.

However, there are some general guidelines your doctor may give you:

  • You’ll practice stair — climbing in the hospital and should be able to do this by the time you leave
  • You should have no restrictions on leaving your home as long as your safety and comfort are assured. Just don’t tire yourself out; a good balance of exercise, rest, and relaxation is best for helping your body heal and gain strength
  • When to resume driving a car, going to work, and/or participating in sports activities are all highly individualized decisions. Be sure to follow your doctor’s or orthopaedic surgeon’s advice and recommendations

After Surgery — Limitations

For approximately 12 weeks after surgery certain limitations are placed on your activities. When fully recovered, most patients can return to work. However, some types of work may not be advisable for individuals with a joint replacement. These types of work include:

  • Construction work
  • Certain types of carpentry
  • Occupations that involve repeated high climbing

Athletic activities that place excessive stress on the joint replacement will need to be avoided. Examples of these activities include:

  • Skiing (snow or water)
  • Basketball
  • Baseball
  • Contact sports
  • Running
  • Frequent jumping

Realistic Expectations

Physical Activities
After joint replacement, acceptable physical activities should:

  • Not cause pain — including pain felt later
  • Not jar the joint — running and jumping should be avoided
  • Not place the joint in the extremes of its range of motion
  • Be pleasurable

Longevity of Joint Replacement
It is impossible to predict in individual cases how long a joint replacement will last. Many factors determine the outcome including:

  • Age
  • Weight
  • Activity level
  • Bone strength

What is Total Joint Replacement?

Total joint replacement is a surgical procedure in which certain parts of an arthritic or damaged joint, such as a hip, knee or shoulder joints, are removed and replaced with a plastic or metal device called a prosthesis. The prosthesis is designed to enable the artificial joint to move just like a normal, healthy joint.

Hip replacement involves replacing the femur (head of the thighbone) and the acetabulum (hip socket). Typically, the artificial ball with its stem is made of a strong metal, and the artificial socket is made of polyethylene (a durable, medical grade plastic). In total knee replacement, the artificial joint is composed of metal and polyethylene and it is used to replace the diseased joint. The prosthesis is anchored into place with bone cement or is covered with an advanced material that allows bone tissue to grow into it.

In shoulder replacement surgery, the artificial shoulder joint can have either two or three parts, depending on the type of surgery required.

  • The humeral component (metal) is implanted in the humerus.
  • The humeral head component (metal) replaces the humeral head at the top of the humerus.
  • The glenoid compontent (plastic) replaces the surface of the glenoid socket.

Total joint replacements of the hip, knee, and shoulder have been performed since the 1960s. Today, these procedures have been found to result in significant restoration of function and reduction of pain in 90% to 95% of patients. While the expected life of conventional joint replacements is difficult to estimate, it is not unlimited. Today’s patients can look forward to potentially benefiting from new advances that may increase the lifetime of the prostheses.

Total Joint Replacement

Total joint replacement is usually reserved for patients who have severe arthritic conditions. Most patients who have artificial hip or knee joints are over 55 years of age, but the operation is being performed in greater numbers on younger patients thanks to new advances in artificial joint technology.

Circumstances vary, but generally patients are considered for total joint replacement if:

  • Functional limitations restrict not only work and recreation, but also the ordinary activities of daily living
  • Pain is not relieved by more conservative methods of treatment, such as those described above, by the use of a cane, and by restricting activities
  • Stiffness in the joint is significant
  • X-rays show advanced arthritis or other problems

Total Hip Joint Replacement

You Don’t Have to Live with Joint Pain

Your joints are involved in almost every activity you do. Simple movements such as walking, bending, and turning require the use of your hip and knee joints. Normally, all parts of these joints work together and the joint moves easily without pain. But when the joint becomes diseased or injured, the resulting pain can severely limit your ability to move and work. Osteoarthritis, one of the most common forms of degenerative joint disease, affects an estimated 43 million people in the United States.1 Whether you are considering a total joint replacement, or are just beginning to explore available treatments, this website is for you. It will help you understand the causes of joint pain and treatment options. Most importantly, it will give you hope that you may be able to return to your favorite activities.

Once you’re through reading this website, be sure to ask your doctor any questions you may have. Gaining as much knowledge as possible will help you choose the best course of treatment to relieve your joint pain — and get you back into the swing of things.

What is a Hip Joint?

Your hip joint is a ball-and-socket joint, formed by the ball, or femoral head, at the upper end of the thighbone, and the rounded socket, or acetabulum, in the pelvis. The bone ends of a joint are covered with a smooth, tough material called cartilage. Normal cartilage cushions the bones and allows nearly frictionless and pain-free movement. The rest of the surfaces of the joint are covered by a thin, smooth tissue lining called the synovium. The synovium produces fluid that acts as a lubricant to reduce friction and wear in the joint.

Common Causes of Joint Pain

Osteoarthritis (OA)
Sometimes called degenerative arthritis because it is a “wearing out” condition involving the breakdown of cartilage and bones. When cartilage wears away, the bones rub against each other, causing pain and stiffness. OA usually occurs in people aged 50 years and older, and frequently in individuals with a family history of arthritis.

Rheumatoid Arthritis (RA)
Causes the synovium to become thickened and inflamed. In turn, too much synovial fluid is produced within the joint space, which causes a chronic inflammation that damages the cartilage. This results in cartilage loss, pain, and stiffness. RA affects women about 3 times more often than men, and may affect other organs of the body.

Post-traumatic Arthritis
May develop after an injury to the joint in which the bone and cartilage do not heal properly. The joint is no longer smooth and these irregularities lead to more wear on the joint.

Avascular Necrosis
Can result when bone is deprived of its normal blood supply. Without proper nutrition from the blood, the bone’s structure weakens and may collapse and damage the cartilage.

Paget’s Disease
A bone disease that often affects the hip. Bone formation is sped up, causing the density and shape of the bone to change. Joint pain can also be caused by deformity or direct injury to the joint. In some cases, joint pain is made worse by the fact that a person will avoid using a painful joint, weakening the muscles and making the joint even more difficult to move.

Treatment Options
Following the orthopaedic evaluation, your orthopaedic surgeon will review and discuss the results with you. Based on his or her diagnosis, your treatment options may include:

  • Medication
  • Joint fluid supplements
  • Physical therapy
  • Joint replacement

Total Hip Replacement

Hip replacement is one of the most important surgical advances of this century. This surgery helps more than 300,000 Americans each year1 to relieve their pain, and get back to enjoying normal, everyday activities. Hip replacement involves the removal of arthritic bone ends and damaged cartilage and replacing them with prosthetic implants that replicate the hip joint.

Hip replacement surgery may be considered when arthritis limits your everyday activities such as walking and bending, when pain continues while resting, or stiffness in your hip limits your ability to move or lift your leg. Hip replacement may be recommended only after careful diagnosis of your joint problem. It is time to consider surgery if you have little pain relief from anti-inflammatory drugs or other treatments, such as physical therapy, do not relieve hip pain. Hip replacement can help relieve pain and get you back to enjoying normal, everyday activities.

Total hip replacement is often reserved for patients who:

  • Have a painful, disabling joint disease of the hip resulting from a severe form of arthritis
  • Are not likely to achieve satisfactory results from less invasive procedures, such as arthrodesis (artificial stiffening or fixation of the joint)
  • Have bone stock that is of poor quality or inadequate for other reconstructive techniques

In a total hip replacement operation, the surgeon replaces the worn surfaces of the hip joint with an artificial hip joint. The worn head of the femur (thigh bone) is replaced with a metal or ceramic ball mounted on a stem; the stem is placed firmly into the canal of the thigh bone at its upper end. The acetabulum (hip socket) is prepared and implanted with a metal cup and plastic or ceramic insert. The ball and insert glide together to replicate the hip joint.


1. Orthopedics.about.com website, Feb. 2006.

Total Hip Implants
The conventional arrangement of a metal ball into a special plastic (polyethylene) cup has been shown to have positive results over the years. How long it will last depends not only on age, but also on a patient’s activity level.

Another factor that may affect the durability of a total hip replacement is the bearing surface. The bearings are the two parts of the artificial hip that glide together throughout motion. These bearings can be metal-on-polyethylene, metal-on-metal, ceramic-on-polyethylene or ceramic-on-ceramic.

Technologies That May Impact Implant Performance
There have been significant advancements in improving the bearing surfaces in total hip replacement. Ceramic-on-ceramic bearings provide superior wear performance.1 Stryker’s ceramic-on-ceramic system has demonstrated significantly lower wear than metal-on-polyethylene systems in the laboratory; therefore, it is anticipated that these improved wear characteristics may extend the life of the implant.

There are also new, advanced polyethylene implants available that have demonstrated extremely low wear in the laboratory, and they are expected, over time, to have similar wear performance clinically.2

Your physician will discuss the exact type of prosthesis and surgical procedure with you.

Complications of Hip Replacement
As with any surgery, there is risk of complications after hip replacement surgery. However, they are relatively rare. Blood clots are the most common complication after surgery. Your orthopaedic specialist may prescribe one or more measures to prevent a clot from forming in your leg veins. These measures may include special support hose, inflatable leg coverings and blood thinners.

2. Stryker Test Report RD–04–099.


Generally, after hip replacement surgery, you may spend approximately 3 to 5 days in the hospital. Most hip replacement patients begin standing and walking with the help of a walker and a physical therapist the day after surgery.

Recovery varies with each person. It is essential that you follow your orthopaedic surgeon’s instructions regarding home care during the first few weeks after surgery; especially the exercise program you are prescribed. You should be able to resume many normal light activities of daily living within 3 to 6 weeks following surgery. Some discomfort with activity, and at night, is common for several weeks. Complete recovery can take from about 3 to 6 months.

While most people will gradually increase their activities and play golf, doubles tennis, shuffleboard or bowling, you will be advised to avoid more active sports, such as jogging, singles tennis and other high impact activities.

Your Hip Joint

A joint is formed by the ends of 2 or more bones. The hip must bear the full force of your weight and consists of two main parts:

  • A ball (femoral head) at the top of your thigh bone (femur)
  • A rounded socket (acetabulum) in your pelvis

Normal hip joint, showing healthy articular cartilage

Diseased hip joint, showing worn cartilage

What Causes Hip Joint Pain?
One of the most common causes of joint pain is arthritis. The most common types of arthritis are:

  • Osteoarthritis (OA)
  • Rheumatoid Arthritis (RA)
  • Post-traumatic Arthritis
  • Avascular Necrosis

Hip Surgery
May be suitable for patients who:

  • Have a painful, disabling joint disease of the hip resulting from a severe form of arthritis
  • Are not likely to achieve satisfactory results from less invasive procedures, medication, physical therapy, or joint fluid supplements
  • Have bone stock that is of poor quality or inadequate for other reconstructive techniques

Total Knee Joint Replacement

Are You Considering Knee Replacement Surgery?

Each patient is unique, but generally candidates for knee replacement surgery have:

  • Pain severe enough to restrict not only work and recreation, but also the routine activities of daily living
  • Pain that is not relieved by more conservative methods of treatment, such as reduced activity, medication or physical therapy
  • Significant joint stiffness and loss of mobility
  • X-rays that show advanced arthritis or other degenerative problems

The National Institutes of Health (NIH) has concluded that knee replacement surgery is “a safe and cost-effective treatment for alleviating pain and restoring function in patients who do not respond to non-surgical therapies.”1 According to the American Academy of Orthopaedic Surgeons, knee replacement procedures have resulted in significant restoration of function and reduction of pain in about 90% of patients.2 As you read,make a note of anything you don’t understand. Your doctor will be happy to answer your questions so that you’ll feel comfortable and confident with your chosen treatment plan.

Knee Basics: What You Need to Know

Knee Anatomy and Function
The knee is the largest joint in the body and is central to nearly every routine activity. The knee joint is formed by the ends of 3 bones: the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and the kneecap (patella). Thick, tough tissue bands called ligaments connect the bones and stabilize the joint. A smooth, plastic like lining called cartilage covers the ends of the bones and prevents them from rubbing against each other, allowing for flexible and nearly frictionless movement. Cartilage also serves as a shock absorber, cushioning the bones from the forces between them. Finally, a soft tissue called synovium lines the joint and produces a lubricating fluid that reduces friction and wear.

Arthritis: The Leading Cause of Knee Pain
One of the most common causes of knee pain and loss of mobility is the wearing away of the joint’s cartilage lining. When this happens, the bones rub against each other, causing significant pain and swelling — a condition known as osteoarthritis. Trauma or direct injury to the knee can also cause osteoarthritis. Without cartilage there is no shock absorption between the bones in the joint. This allows stress to build up in the bones and contributes to pain.

Knee Replacement

Knee replacement is a surgical procedure — performed in the U.S. since the 1960s — in which a diseased or damaged joint is replaced with an artificial joint called a prosthesis.Made of metal alloys and high-grade plastics (to better match the function of bone and cartilage, respectively), the prosthesis is designed to move just like a healthy human joint. Over the years, knee replacement techniques and instrumentation have undergone countless improvements. Today, knee replacement is one of the safest and most successful types of major surgery; in about 90% of cases it is complication-free and results in significant pain relief and restoration of mobility.1

Knee Implants That Promote Easier Motion1,2,3

Stryker knee replacements are different than traditional knee replacements because they are designed to work with the body to promote easier motion,1,2,3 and a study has shown a more rapid return to functional activities after surgery.2 This is due to the single radius design of the knee implant. Single radius means that as your knee flexes, the radius is the same, similar to a circle, requiring less effort from your quadriceps muscle.1,4,6

Because the thigh muscle (the quadriceps) is attached to your knee, it is unavoidably involved in the surgery. Therefore, the quadriceps muscle can become a source of discomfort or pain during your recovery period. The quadriceps muscle plays an important role in your ability to move your legs so it also has a major impact on your recovery and how quickly you can get back to living your life.2

Knee implants designed to last longer5
Several factors influence how long an implant will continue to perform. Stryker knees are designed to resist wear in many ways — they use advanced bearing surfaces; they’re balanced to help avoid excessive stress in any one spot; and, they’re sized to better fit your personal anatomy. X3 Advanced Bearing Technology has demonstrated up to 96% decrease in wear in laboratory testing compared to competitive premium bearing technologies.5

What Typically Happens During the Surgery

To begin the surgery, the surgeon will make an incision on the front of your knee, cutting through the tissue surrounding the muscles and bone. The kneecap, or patella, is rotated to the outside of the knee, to help your doctor see the area where the implant will be placed. The surgeon will use special cutting instruments to measure and make precise cuts of the bone. The end of the femur (thigh bone) is cut into a shape that matches the corresponding surface of the metal femoral component. The femoral component is then placed on the end of the femur.

The tibia (shin bone) is prepared with a flat cut on the top. The exposed end of the bone is sized to fit the metal and plastic tibial components. The metal tibial component is inserted into the bone. Then a plastic insert is snapped into the tibial component. The femoral component will slide on this plastic as you bend your knee.

If needed, the patella (kneecap) is also cut flat, and fitted with a plastic patellar component. Bone cement may be used to help secure the implants onto your bone. Your surgeon will conduct several tests during the surgery to ensure the correct sized components are used to help you regain good balance and motion in your knee. Your surgeon will then close the wound in layers with stitches and/or staples.

Risks Associated with Knee Replacement

But as good as the results can be, knee replacement is major surgery, and as such, there are certain risks and expectations that must be recognized. As with any major surgical procedure, patients who undergo total joint replacement are at risk for certain complications, the vast majority of which can be successfully avoided or treated. In fact, the complication rate following joint replacement surgery is very low. Serious complications, such as joint infection, occur in less than 2% of patients.1 Other possible complications include blood clots and lung congestion, or pneumonia. Talk to your doctor for a complete assessment of the potential risks.

Life After Knee Replacement
The vast majority of individuals who have joint replacement surgery experience a dramatic reduction in joint pain and a significant improvement in their ability to participate in the activities of daily living. However, joint replacement surgery will not allow you to do more than you could before joint problems developed. Your doctor will recommend the most appropriate level of activity following joint replacement surgery.

Don’t Let Knee Pain Slow You Down

Don’t let severe knee pain limit your activities. If you haven’t experienced adequate relief with medication and other conservative treatments, joint replacement may provide the pain relief you long for and enable you to return to your favorite activities. Remember, even if your doctor recommends knee replacement for you, it is still up to you to make the final decision. The ultimate goal is for you to be as comfortable as possible with your choice — and that always means making the best decision based on your own individual needs.

What Causes Knee Joint Pain?
One of the most common causes of joint pain is arthritis. The most common types of arthritis are:

  • Osteoarthritis (OA)
  • Rheumatoid Arthritis (RA)
  • Post-traumatic Arthritis

Knee Surgery
May be suitable for patients who:

  • Have a painful, disabling joint disease of the knee resulting from a severe form of arthritis
  • Are not likely to achieve satisfactory results from less invasive procedures, medication, physical therapy, or joint fluid supplements
  • Have bone stock that is of poor quality or inadequate for other reconstructive techniques

new-knewwTotal Knee Joint Replacement

  • End surface of femur replaced with metal
  • End surface of tibia replaced with metal
  • Plastic liner is inserted between femur and tibia to reduce wear
  • Patella is resurfaced with plastic

Every individual is different and every treatment plan is different. The length of hospital stay after joint replacement varies and depends on many factors including age and physical ability.

Estimated Recovery Schedule

  • In-hospital Recovery: 2 – 5 days
  • Significant Functional Improvement: 6 weeks – 3 months
  • Maximal Improvement: 6 – 12 months

Recovery — Rehabilitation
Following joint replacement the physical therapist begins an exercise program to be performed in bed and in the therapy department. The physical therapist or another member of the staff works with the patient to help the patient:

  • Regain muscle strength
  • Increase range of motion

20 Tips to Help You Prepare for Joint Replacement Surgery

Getting physically and psychologically ready for joint replacement surgery can be an intense process. Those who are better prepared tend to achieve better results. Here are 20 tips for achieving optimal results: *

  1. Find an experienced surgeon – Your orthopaedic surgeon will become an important person in your life for years to come. Make sure you are comfortable with your doctor’s approach, level of experience and personality.
  2. Educate yourself about your surgery – Learn as much as possible about pre-op preparations, the procedure, post-op care, precautions and possible complications. Ask your doctor to go over your surgical plan, outcomes and long-term care in detail.
  3. Seek a second opinion – Your surgeon should honor your right to confer with another, well-respected orthopedist if you have any doubts.
  4. Plan ahead – Schedule surgery when you can afford to take time off from work, and when it will be least disruptive to your family.
  5. Weigh risks versus benefits – Reconcile the big picture in your mind so you don’t go into surgery dwelling on risks or potential complications.
  6. Have a positive attitude – Be encouraged and focus on the high rate of success for total joint procedures.
  7. Talk with past patients – Hearing about other’s successes can help you gain perspective and ease your mind.
  8. Visualize getting your life back – The pain and deterioration of your joint severely diminished your quality of life. Think about how much things will improve after surgery.
  9. Realize feeling tense or anxious is normal – Don’t fight it!
  10. Actively participate – Make a commitment to do your part to ensure a positive outcome and assume responsibility for your own care (i.e., follow precautions, do exercises daily, etc.). Consult with your orthopaedic surgeon with questions or concerns.
  11. Practice on crutches – If you have spent time on crutches before, reacquaint yourself with them so the awkwardness won’t be overwhelming after surgery.
  12. Don’t view the recovery process as time lost – This is time to rest and recuperate. Time invested in rehabilitation is necessary for better health.
  13. Prioritize physical therapy – Realize your physical therapy and postop exercise regimen are critical for a successful outcome. Think of each exercise as a stepping-stone toward improved strength, range of motion and function.
  14. Prepare for downtime – Remember you will be laid up for about 6 weeks. Organize, schedule appointments and take care of as much business as possible before surgery.
  15. Take multi-vitamins and eat well-balanced meals – Be particularly health conscious during the weeks and months leading up to surgery to promote better healing.
  16. Be conscious of infection – If you have any sign of any kind of infection anywhere in your body you must postpone surgery.
  17. Donate autologous units of blood – You can donate your own blood in the weeks prior to surgery to be held for your operation.
  18. Ask about current medications – Find out if you need to stop taking any prescription, over-the-counter or herbal remedies before surgery.
  19. Adapt your environment – Get ready for homecoming before you go to the hospital by having a raised toilet seat, reachers and other adaptive equipment already available.
  20. Arrange for help – Plan for someone to be with you, especially for the first week or two at home. If no one is available, make arrangements to enter a post-op inpatient rehabilitation facility until you are independent enough to care for yourself at home.

Never Lose Sight of Your Goals

The surgeon and surgical team do their work in the operating room. The rest is up to you. With inspiration and hard work, you will achieve great success throughout your rehabilitation, recovery and beyond.

What to Expect: Surgery Expectations

If you’re reading this website, you are likely scheduled for joint replacement surgery. The information in this website is intended to help you prepare for the day of surgery and answer some questions that may be on your mind. This website will provide you with information so you know what to typically expect before, during and after your joint replacement. By better understanding the surgical experience, hopefully your mind will be put at ease.

This information was written by medical professionals. It provides general responses to frequently asked questions from patients like you. Each patient is unique and therefore patient needs may be unique. Please discuss your specific instructions with your orthopaedic specialist.

Before Surgery

What kinds of tests will I need before surgery?
All patients are required to have routine blood work and urinalysis performed. These tests should be performed within 14 days of the scheduled surgery in order to be acceptable. In addition, all patients are required to have a physical examination which can be performed at any time within 30 days of the surgical date. Patients over the age of 50 are required to have an EKG and chest x-ray performed within 30 days of the surgical date. Patients below the age of 50 with any cardiac or respiratory history may also be required to have these tests performed.

Most pre-admission testing and physical evaluations can be performed either by the patient’s personal physician or at the hospital where the procedure will be performed.

Please be advised that if an abnormal exam or test result is reported, a further evaluation or repeat testing may be required. This does not necessarily mean surgery is canceled, but for your own safety, it is standard procedure to conduct further investigation.

Will I need to donate blood before surgery?
The patient will receive blood from the hospital blood bank if necessary. Hospitals follow universal guidelines in screening blood and blood products to assure the patient’s safety as much as possible in this situation.

Are there any medicines I need to take before surgery?
It is recommended that patients take an iron supplement prior to surgery particularly if you will be donating your own blood. These supplements may be purchased at any drugstore or recommended by your family physician. Consult your physician for suggested iron supplements before purchasing them.

How long will I be in the hospital?
For joint replacement surgery, most patients are hospitalized for 4 days, including the day of surgery. Hospital stays may vary if the patient is either going to a rehabilitation center, a sub-acute facility, or not cleared medically or surgically for discharge home.

Please be advised that most insurance plans cover 3-4 days of acute care in the hospital for total knee replacement surgery. Some insurances do provide for further care in several other types of facilities. It is advisable for each patient to contact their health insurance provider for specific programs covered and to obtain these provisions in writing.

What should I bring to the hospital?
All patients should bring with them personal toiletries and shaving gear, loose fitting, comfortable clothing, non-skid shoes or slippers (slip-on type with closed back preferred), a list of their current medications (including dosages), and any paperwork the hospital may have requested.

Please be advised that the hospital provides pajamas, gowns, robes, slipper socks, and a small toiletries supply. Most patients, however, do supplement these with the articles outlined above, at least in terms of toiletries.

In addition, if you have an assistive device that you plan to use after discharge (i.e., walker, cane, crutches) but are not currently using, you should have someone bring this in prior to discharge so the physical therapist can check to assure that it is the adequate size for you. Contact the hospital where your surgery will take place for specific information regarding your hospital stay and assistive devices.

It is not recommended that you bring radios, TVs, or large amounts of cash.

When should I arrive at the hospital for my surgery?
Patients are generally requested to arrive at the hospital 2 hours prior to the scheduled surgery time. This allows time for you to go through the admission process, change into hospital clothing, and meet the anesthesiologist and nursing personnel who will be with you during your surgery and will be able to answer your questions.

Please be advised that you should not eat or drink from midnight on the day of your surgery. In some cases your physician may allow you to take a medication the morning of surgery. If this is the case, you should take the medication with the least amount of water necessary. Report to the admitting nurse any medications (and dosage) you may have taken.

Can my family stay with me during this time?
Families may stay with patients until the patient is taken to the operating room. Consult your hospital for their specific rules.

Will anyone contact me before surgery to discuss any concerns I may have?
The orthopaedic surgery patients are followed throughout their experience by a case manager. The case manager’s role is to assist the patient in planning for discharge, answer any questions the patient may have in terms of their case, and provide a supportive link throughout the patient’s surgical experience. You will be contacted by the case manager prior to your surgery and assisted in planning for your individualized case management. The case manager will also schedule you to attend a pre-operative class in which you and your family members will receive instructions for each phase of your surgical experience. The classes are held on a rotating weekly schedule for total hip and total knee patients and are highly recommended. By attending class, both you and your case manager are better able to plan for your upcoming surgical experience. Contact the hospital for further details about the pre-operative class.

Day of Surgery

What type of anesthesia will I have?
Most cases are performed under spinal anesthesia. Unless there is a recommendation to the contrary from the anesthesiologist, this is the method preferred. You will be meeting with the anesthesiologist on the day of surgery and at that time any questions or concerns regarding this will be addressed.

How long will the surgery take?
Surgery times may vary depending upon the difficulty of your case. The surgery may take several hours. Generally, you may spend 2-3 hours in surgery and 2-3 hours in the recovery room.

Will the surgeon see my family immediately after the surgery is completed?
The surgeon or one of his assisting surgeons will try to meet with family members immediately after surgery. If for any reason the family misses seeing the surgeon, they should contact the surgeon’s office the next day and all efforts will be made to arrange a time for the surgeon and family to discuss the patient’s surgery.

After Surgery

What will my hospital stay be like?
The first night of your stay, you will most likely be somewhat “groggy” from the medications you receive in surgery. You will be taken to your hospital room directly from the recovery room in your hospital bed to avoid transferring you from stretcher to bed. Once you are fully awake, you will be able to eat and drink as tolerated. Your vital signs, urinary output, and any drainage will be monitored closely by the nurses on the orthopaedic surgery floor. Appropriate pain medicine for the first 24 hours may be administered by intravenous method.

Starting on day one post-operatively, you will be getting out of bed and attending physical and occupational therapy sessions. These sessions are vital to your progress and are arranged for 2-3 sessions. The physical therapists attending you will teach you the exercises needed for your optimal recuperation and instruct you on your weight bearing technique using a walker or crutches. The occupational therapist is trained to assist you in adapting your activities of daily living to your post-operative limitations. Activities such as bathing, dressing, using the bathroom, transfers from bed to chair, ambulation, and stair climbing will all be addressed during these sessions. Instructions for traveling by various modes of transportation will also be discussed.

Will I see my doctor regularly while in the hospital?
The attending doctors make rounds daily on their patients whenever possible. In addition, the orthopaedic resident doctors or physician assistants make rounds twice daily to monitor your progress and make any changes required for your care. The case manager will also meet with you (and family members if necessary) in order to assure the proper discharge plan for your particular case. Arrangements for transfer to a rehabilitation floor or sub-acute floor either at the hospital or elsewhere will be evaluated by you and the case manager if this becomes an option.

How will I know whether to go home or to another facility for further rehab?
In general, if you live with someone who will be assisting you, discharge home is the usual procedure. Arrangements for further home or outpatient physical therapy will be made by the case manager. Most patients can go directly home if they are deemed safe by the physician and therapists. While not required, it is highly recommended to have someone to assist you the first 48-72 hours after discharge on a full-time basis and perhaps part-time the first week or two after this. If you live alone or are in an environment at home where your safety is in question (i.e., physical therapy/ occupational therapy goals not met), you may be recommended for placement in a rehabilitation center. These facilities are usually available to a patient for a 3-5 day stay, with emphasis on returning the patient home in a short period after aggressively addressing any problems with patient independence. If you live alone or are not progressing rapidly enough in therapy sessions and it is unlikely you will be able to do so in a rehab setting, a sub-acute facility may be recommended for a longer period of recuperation. The choices available depend upon the patient’s insurance coverage and, therefore, will need to be discussed by the patient, the case manager, and the insurance company as warranted.

When will I be ready for discharge?
Depending on whether you go home or to another facility to recuperate will play a role in when discharge occurs. In general, a patient may be transferred to the rehabilitation floor on the 2nd post-operative day. Transfer to the sub-acute floor may also occur on the 2nd or 3rd post-operative day. If you are being transferred to another facility, transfers usually occur on the 2nd or 3rd post-operative day as well. Discharges to home usually occur on the 3rd to 4th post-operative day in general.

Discharge Day — Recovery

What can I expect the first few days after discharge?
Expect a time of transition. You may feel overwhelmed the first day or two after discharge and may even feel you’ve made a mistake coming home so soon.This may occur even after discharge from a rehab or sub-acute floor. Be patient, and give yourself some time to adjust. Many patients report that after the first day or two of practical problem solving and establishing a routine, they experience a change in their progress and notice a definite upward trend in their recuperation. If, on the other hand, you are experiencing pain or discomfort or have concerns about your condition, please consult your physician.

In addition, during this phase of discharge, usually within the first 24-72 hours, you will receive a telephone check-up from your case manager. You will be asked several questions to establish your progress and whether your post-discharge home or outpatient therapies have been started. This phone call also allows you to ask any questions or voice concerns regarding your home situation so they can be addressed.

Do I need someone to stay full-time with me when I go home?
It is our recommendation that someone be with you the first 24-72 hours after discharge. Many patients do live alone and we realize this is not always possible. But if you have a relative or a friend who offers to stay with you, take this offer for your own ease of mind. Many times patients have family members or friends who stay with them all day in the hospital. While this is certainly welcomed, it is often more helpful that this person be available after you leave the hospital. If you do live alone and either are discharged from rehab or from the orthopaedic floor with no help available at home, perhaps a friend or neighbor can call you daily to check on your progress. In addition, if home care has been arranged, these visits usually can be arranged so that someone is checking on you daily. The case manager will be discussing options available for your particular circumstances, and together you will develop a discharge plan, which will address your particular situation.

When can I go up and down stairs?
Stair climbing will be practiced in the physical therapy program before you leave the hospital. Most patients can climb stairs before leaving the hospital. If you live in a 2-story home and have practiced stair climbing, stairs can be done one to two times a day after discharge, depending upon your comfort level and provided that your physician has approved this activity.

Will I need pain medicine after I’m discharged from the hospital?
Most patients do require a short-term course of pain medicine. Renewals on these prescriptions can be obtained by calling your surgeon’s office. Expect to be on some type of pain medication for several weeks after discharge. Most patients take these medications especially at night or before therapy sessions.

How long will I need to use my walker or crutches?
Walkers and/or crutches are usually used the first 6 weeks after surgery. You will then be allowed to use a cane, which again will be used for approximately 6 weeks. After that time, most patients do not need any support for walking.

When can I go outside?
Consult your physician for a recommended time to engage in outdoor activities. Comfort and safety should be the primary guidelines for doing this. It is suggested to start with short trips at first, perhaps to therapy (if nearby) or your local supermarket or church, for example. Gradually increase the number and length of outside activities as you feel more comfortable.

When can I drive?
Driving routinely is not permitted before 6 weeks from the time of your surgery. However, some physicians may allow the patient to drive earlier if they feel the patient can do so safely. The type of surgery, side of surgery (left vs. right leg), and the patient’s overall general condition plays a part in this decision.

If you feel you will need to drive earlier than the 6-week routine prescribed, you should discuss this with your surgeon and obtain his/her approval. Consult your physician for further details.

When will I be able to return to work?
This varies with each patient. In general, patients usually do not return to work until after their first check-up at 6 weeks from surgery. Some patients do return to work earlier if they can do so safely. This should be discussed with your physician so that the best decision for your individual situation is made.

When will I be able to participate in sports activities?
Depending upon what activity you want to participate in will determine when you can safely start these activities again. Swimming, walking distances (hiking), bicycle riding, golfing, and other low impact sports activities can likely be tried after a few weeks. Returning to high impact activities such as jogging, tennis, or aerobics exercises will probably not be recommended for quite some time. Your return to any of these activities should be discussed with your surgeon.

When will I be able to have sexual intercourse after my surgery?
In most cases, sexual activities can be resumed when the patient feels comfortable enough to do so. If the patient has been cautioned to maintain certain position restrictions, these restrictions should be followed in this instance also. In general, most patients resume their normal sexual activities between 4-6 weeks following surgery.


Hopefully this website has answered some of your questions about joint replacement surgery and provided you with a better understanding of what to expect during the surgical experience. Your orthopaedic specialist will be happy to answer any additional questions so that you’ll feel comfortable and confident with your upcoming surgery. As individuals vary, please discuss your specific instructions with your orthopaedic specialist.

Life After Total Joint Replacement
The vast majority of individuals who have joint replacement surgery experience a dramatic reduction in joint pain and a significant improvement in their ability to participate in the activities of daily living. Your physician will recommend the most appropriate level of activity following joint replacement surgery.

It is important to understand that there are risks associated with any major surgical procedure and total joint replacement is no exception. Although the occurrence of complications is low in number, each patient needs to be informed of these possible risks prior to surgery. In all cases, discussion between the patient and the treating physician is imperative so that the patient is aware of potential complications and how to minimize them.

Possible Complications of Surgery

The complication rate following joint replacement surgery is very low. Serious complications, such as joint infection, occur in less than 2% of patients. Nevertheless, as with any major surgical procedure, patients who undergo total joint replacement are at risk for certain complications — many of which can be successfully avoided and/or treated.

Possible complications include:

Infection: Infection may occur in the wound or within the area around the new joint. It can occur in the hospital, after the patient returns home, or years later. Following surgery, joint replacement patients receive antibiotics to help prevent infection. Joint replacement patients may also need to take antibiotics before undergoing any medical procedures to reduce the chance of infection spreading to the artificial joint.

Blood Clots: Blood clots can result from several factors, including the patient’s decreased mobility following surgery, which slows the movement of the blood. There are a number of ways to reduce the possibility of blood clots, including:

  • Blood thinning medications (anticoagulants)
  • Elastic support stockings that improve blood circulation in the legs
  • Plastic boots that inflate with air to promote blood flow in the legs
  • Elevating the feet and legs to keep blood from pooling
  • Walking hourly

Lung Congestion: Pneumonia is always a risk following major surgery. To help keep the lungs clear of congestion, patients are assigned a series of deep breathing exercises.

What to Expect Following Your Surgery

On the first day after your surgery, you may get out of bed and begin physical and occupational therapy — typically for several brief sessions a day. These are first steps on your way to getting back into the routines of your life!

In the days following surgery, your condition and progress will continue to be closely monitored by your orthopaedic specialist, nurses, and physical therapists. A good deal of time will be given to exercising the new joint, as well as deep-breathing exercises to prevent lung congestion. Gradually, pain medication will be reduced, the IV will be removed, diet will progress to solid food, and you will become increasingly mobile. Every individual is different, and insurance coverage will differ as well. Generally speaking, a total of four days (including the day of the surgery) in the hospital is typical.

Joint replacement patients are generally discharged from the hospital when they are able to achieve certain rehabilitative milestones, such as getting in and out of bed unassisted or walking 100 feet. Your physician will assess your progress and decide whether you are ready to go directly home or to a facility that will assist with your rehabilitation.

Usually a case manager is assigned to work with you as you move through your rehabilitation routines. As the days progress, expect to become more independent using two crutches or a walker.

If you need to work with a physical therapist after your joint replacement surgery, the therapist will begin an exercise program that you can perform in bed and in the therapy department. The physical therapist will work with you to help you gain confidence and increase your range of motion.

To help you gain confidence with your new joint, the physical therapist (or nurses) will also show you:

  • How to get out of bed
  • How to use the bathroom
  • How to get dressed

Leaving the hospital will depend on when you “graduate” from physical therapy. When you leave the hospital, the physical therapist should give you a list of activities, exercises, and “do’s and don’t’s” to follow. An occupational therapist or nurse may also be assigned to help with special needs. An occupational therapist may show you how to use certain devices that assist in performing daily activities, such as putting on socks, reaching for household items, and bathing.

You shouldn’t be surprised if you feel a little shaky and uncertain for the first day or two after you’re discharged. However, you should soon get a routine going and gain confidence in your new joint — the start of a new life with less pain. (As with any surgery, expect to take pain medication for a few days while you are healing.)

If you had a hip or knee replacement, you may need a walker and/or crutches for about six weeks, then a cane for another six weeks or so. Your doctor or orthopaedic specialist as well as your case manager will be in touch with you, so use these opportunities to ask questions or discuss concerns, and keep your team up-to-date on your progress.

The decision to resume a normal daily routine is one that only you and your doctor or orthopaedic surgeon can make. However, there are some general guidelines that your doctor may give you.

  • You should have no restrictions on leaving your home as long as your safety and comfort are assured. Just don’t tire yourself out; a good balance of exercise, rest, and relaxation is best for helping your body heal and gain strength.
  • You may need to take antibiotics before dental work (including dental cleaning) and any surgical procedure that could allow bacteria to enter the bloodstream. Ask your healthcare provider whether you will need to take antibiotics at certain times to prevent infection.
  • When to resume driving a car, going back to work, and/or participating in sports activities are all highly individualized decisions. Be sure to follow your doctor’s or orthopaedic specialist’s advice and recommendations.

Life After Surgery: Life After Joint Replacement

Regaining Mobility Safely, Slowly, Securely


At first

Most people experience reduction in joint pain and improvement in their quality of life following joint replacement surgery. While joint replacement surgery may allow you to resume many daily activities, don’t push your implant to do more than you could before your problem developed.

Give yourself at least six weeks following surgery to heal and recover from muscle stiffness, swelling and other discomfort. Some people continue to experience discomfort for 6-12 weeks following their joint replacement.

During visits to the physical therapist’s office, your therapist may use heat, ice or electrical stimulation to reduce any remaining swelling or pain. You should continue to use your walker or crutches as instructed.

Your physical therapist may use hands-on stretches for improving range of motion. Strength exercises address key muscle groups, including the buttock, hip, thigh and calf muscles. You can work on endurance through stationary biking, lap swimming and using an upper body ergometer (upper cycle). Physical therapists sometimes treat their patients in a pool. Exercising in a swimming pool puts less stress on your joints and the buoyancy lets you move and exercise easier.

When you are safe putting full weight through the leg, several types of balance exercises can help you further stabilize and control the hip or knee. Finally, you will work with a group of exercises to simulate day-to-day activities, such as going up and down steps, squatting, rising up on your toes, bending down and walking on uneven terrain. You may be given specific exercises to simulate your particular work or hobby demands.

By six weeks, you may be able to return to many normal activities such as driving, bicycling and golf. When you see your surgeon for follow-up two to six weeks after surgery, he or she can advise you on both short and long-term goals.

As a rule, all joint replacement recipients should heed the following limitations during the first weeks after surgery:

  • Expect to use a cane or walker for several weeks
  • No kneeling, bending or jumping for the first month
  • Don’t drive until ok with your doctor (usually 4-6 weeks)
  • No alcohol with pain medication
  • Don’t smoke – it slows healing
  • You may hear some clicking in your knee as it heals; it’s normal
  • Continue wearing elastic stockings for a period of three months following surgery.

In general, physical activities should:

  • Not cause pain, either during activity or later
  • Not jar the joint, such as when running or jumping
  • Not place the joint in extreme ranges of motion
  • Be pleasurable

Additional tips for living with your new joint:

  • Ask for help – while your goal is to eventually do things for yourself, don’t take unnecessary risks by trying to do too much too soon.
  • Recuperation takes approximately 6-12 weeks – you may feel weak during this time. Use ice for swelling and discomfort. Ice your knee for 15-20 minutes after each exercise period to reduce pain.
  • Keep your appointments with your doctor – it’s important to monitor healing and function on a regular basis. You may need to check in with your doctor two to three times during the first two years, and at intervals of two to three years thereafter. During those visits, your surgeon will take X-rays and monitor wear.
  • Under optimal conditions, your artificial joint may last for many active years. You should always consult your orthopaedic surgeon if you begin to have pain in your artificial joint or if you suspect something is not working correctly.
  • Watch for infection – your new joint is a foreign substance to your body. Germs from other infections can move to your new joint and cause infection. Call your family doctor immediately if you have any signs of infection, e.g., skin infection, urinary tract infection, abscessed teeth, etc. Early treatment is crucial.
  • Alert your dentist or family physician – tell them about your joint replacement before any dental work or procedure, such as a cardiac catheter, bladder exam, or surgery. You may always need to take antibiotics first to prevent infection.
  • Your new joint may set off metal detectors in airports and other secured buildings. Your doctor can give you an identification card to carry in your wallet.

Long Term

Most patients have less pain and better mobility after joint replacement surgery. Your physical therapist will work with you to help keep your new joint healthy for as long as possible. This may mean adjusting your activity choices to avoid putting too much strain on your joint. You may need to consider alternate work activities to avoid the heavy demands of lifting, crawling and climbing.

More extreme sports that require running, jumping, quick stopping or starting and cutting are discouraged. More low impact exercises such as cycling, swimming, golfing, bowling and level walking are ideal.
