Partial Knee Replacement

What is Partial Knee Replacement?

Knee arthritis frequently affects only one part of the joint, or one “compartment”. Rather than replacing the entire joint, some patients can benefit from a “partial joint replacement” or a uni-compartmental knee replacement. The advantage is that there is a shorter hospital stay and the recovery after these “partial joint replacements” is faster. Because the undamaged ligaments, cartilage and bone of the knee are retained with a partial knee replacement, patients typically feel that partial knee replacements feel more natural. However, they also have a limited lifespan and eventually, the partial knee replacement generally needs to be converted to a total knee replacement.

Only a small percentage of patients (less than 10%) are candidates for this type of operation. Ask your surgeon whether you would benefit from a uni-compartmental knee replacement.
