Partial Knee Replacement

A partial knee replacement is a surgical procedure designed to treat arthritis that is isolated to just one part of the knee.

 

Instead of replacing the entire joint, only the damaged compartment—most commonly the medial (inside) portion—is resurfaced with smooth, durable implants.

 

The healthy cartilage, bone, and ligaments in the rest of the knee are preserved, allowing the joint to maintain more of its natural motion and feel.

​

Because less bone and soft tissue are removed compared with a total knee replacement, many patients experience a quicker recovery, improved range of motion, and a knee that feels more “normal” during daily activities.

Who Is a Good Candidate?

​

A partial knee replacement is best suited for patients who have:

• Arthritis limited to one compartment of the knee (medial, lateral, or patellofemoral).

• Persistent pain despite nonoperative treatments such as medications, injections, bracing, or physical therapy.

• Good knee range of motion and intact ligaments—especially a functioning ACL.

• Little to no deformity that can be corrected during surgery.

• Stable knees without significant inflammation or symptoms consistent with inflammatory arthritis.​

​

Ideal candidates are typically active adults who want to reduce pain while maintaining a natural-feeling knee and returning to activities they enjoy.
