Total Knee Replacement
Total knee replacement (TKR) is performed in patients with severe wear and loss of knee cartilage due to injury, trauma or inflammation, for various types of arthritis or other aging-related changes in the knee.
In TKR, the worn cartilage is removed and replaced with a combination metal and plastic implants.
Revision Total Knee Replacement
TKR implants have a normal life span of 10-20 years. With time, the artificial components also wear out and will need to be replaced in a “revision” TKR procedure. Implants may also need replacement for infection, pain or other factors as determined by your doctor.
Bilateral Total Knee Replacement
Bilateral total knee replacement means that both knees are replaced. Bilateral TKR may be performed simultaneously at the same surgery on the same day or staged with a wait of several days, weeks or months between the two procedures. This procedure is usually preformed in patients who have severe arthritis in both knees.
In some cases, wear and tear of the knee or arthritis is confined to a single side of the knee. If your doctor determines it appropriate for your individual case, then only the damaged compartment of the knee may be replaced and the healthy part of the knee left alone. This is referred to as a Uni-compartmental knee replacement and only applicable to a small number of patients.
Because a uni-compartmental knee replacement is done through a smaller incision, the surgery is quicker, hospital stay is shorter and patients can rehabilitate and return to normal activities faster.
