Partial Knee Replacement (UKA)

Unicompartmental (partial) knee replacement is a surgical procedure that replaces only the damaged section of the knee joint, preserving the healthy bone, cartilage, and ligaments.The human knee is divided into three compartments: the medial (inside), the lateral (outside), and the patellofemoral (the front of the knee between the kneecap and thighbone). In a partial replacement, the surgeon removes arthritic tissue from just one of these compartments—most commonly the medial side—and caps it with a metal and plastic prosthetic implant.

Frequently Asked Questions

What is the success rate for Unicompartmental (partial) knee replacement?

Clinical success rates exceed 95% with expert surgical technique and physical therapy.

Does a partial knee replacement feel different than a total knee replacement?

Yes. Because the healthy parts of the knee—especially the major ligaments like the ACL and PCL—are preserved, patients often report that a partial knee replacement bends more naturally and feels more like their "own" knee compared to a total knee replacement.

What is the recovery time?

Because the surgical trauma is significantly less, recovery is generally much faster than a total joint replacement. It is frequently performed as an outpatient procedure. Patients typically walk with assistance the same day and can often resume basic daily activities and driving within 3 to 4 weeks.

Will I eventually need a total knee replacement?

It is a possibility. A partial knee replacement only fixes the currently damaged compartment. If osteoarthritis progresses over time and begins to destroy the other, previously healthy compartments of your knee, you may eventually require a revision surgery to convert the partial implant into a total knee replacement.

Are there activity restrictions after a partial knee replacement?

Similar to total joint replacements, you can return to low-impact sports such as swimming, cycling, doubles tennis, and golf once fully healed. However, high-impact activities like running or heavy jumping are typically discouraged to prevent premature wear on the implant or damage to the remaining natural compartments.
