Partial Knee Replacement

Unicompartmental Arthroplasty

Unicompartmental or “partial” knee arthroplasty is designed to treat knee arthritis that is confined to only one part of the knee.

A unicompartmental knee arthroplasty can be thought of as a “half” knee replacement. It does not require the cutting of the anterior or posterior cruciate ligaments, as is required in most total knee replacements, and involves less bone removal.

Who is the typical candidate for Partial Knee Replacement?

Patients with problems localized to only one area of the knee joint may be good candidates for this procedure. For example, unicompartmental knee arthroplasty works very well in patients who have arthritis in only one “half” of the knee and is an excellent option in younger patients.

What are the benefits of Partial Knee Replacement?

Unicompartmental replacement preserves the normal bone and cartilage in areas of the knee joint unaffected by arthritis or other injury-induced damage. This procedure is less invasive, often shortening recovery time and allowing patients to return to activities more quickly than with a total knee replacement.
