Who are the ideal candidates for Partial Knee Replacement?

The procedure for Partial Knee Replacement is most beneficial if your arthritis is confined to a single compartment of the knee joint.

What is the pre-operative routine for Partial Knee Replacement?
The pre-operative routine for Partial Knee Replacement consists of physical examination, x-ray, laboratory testing of blood and urine, and detailed history of past illnesses, surgeries, medications and allergies (if any). You may also be advised to visit your physical therapist that may provide a brief overview of the rehabilitation process after Partial Knee Replacement surgery.
What is the procedure for Partial Knee Replacement?
The procedure of Partial Knee Replacement allows your surgeon to access and replace only the diseased portion of the knee. Here is a brief description of Partial Knee Replacement procedure: The knee joint is exposed with an incision that is 3-4 inch in length. The knee joint is properly balanced. The end of the femur and top of the tibia are shaped with specialized instruments to snugly fit the implants. The surgeon places trial components to ensure proper alignment of all the parts of the knee joint. Once all the parts are properly aligned, the trial components are removed and the prosthetic components are implanted. The incision is then sutured.
What happens in the post-operative period following Partial Knee Replacement?
Hospital stay may range from 1 – 5 days depending on the general condition of the patient. Physiotherapy starts immediately after the Partial Knee Replacement operation while in hospital. This is continued in the outpatient department after discharge from hospital. Most often, the final range of motion achieved is similar to the range of motion prior to Partial Knee Replacement surgery. Usually, sutures or staples are removed in about two weeks time. There might be some (though minimal) residual discomfort and swelling that usually settles down in the next few months. Standard follow up is at 8 weeks, 6 months, and one year after Partial Knee Replacement. After this, yearly follow-up with X-rays is recommended, to allow early detection of possible problems with the prosthesis.
What is the outcome of Partial Knee Replacement?
It is very difficult to predict the life span of any individual knee implant. However, with good surgical technique of Partial Knee Replacement coupled with accurate instrumentation combined with proper patient selection, you can enjoy a trouble free life up to 10 years and beyond.
