Partial Knee Replacement

What’s involved?

Partial knee replacement surgery is a common option for the treatment of osteoarthritis (knee arthritis). Unlike a total knee replacement, this surgery involves removing only the damaged sections of bone and cartilage in the knee. Only the affected areas of the knee are replaced by metal and a high-density plastic layer. These materials are placed to mimic your old joint and cartilage.

“After a partial knee replacement, you can expect to feel less pain and an improved range of motion in the joint. This surgery is all about regaining normal functionality and feel,” says Dr. Rhys Clark.

Am I a candidate?

Knee injuries can be just as complex as the joints themselves. Your knee has three sections– the medial (inside), the lateral (outside), and the patellofemoral (kneecap). For a partial knee replacement to be suitable, the arthritic damage in your knee must be limited to one side and the surrounding ligaments need to be healthy and intact.

“I can assess if you’re a suitable candidate for surgery based on X-ray and CT/MRI imaging. If medication, physical therapy, and/or injections have not been effective in alleviating pain, surgery may be an option for you.”

A helpful (robotic) hand

Rhys uses robotic assistance in partial knee surgeries. A virtual pre-operation is completed prior to your surgery to ensure you have the best possible outcome. While Rhys is still in control of the procedure, the robotic assists in the bone preparation and placement of the implant.

What to expect from surgery

You can usually return home one to three days after your operation. Rehabilitation exercises and further appointments will follow, but the downtime is less than a total knee replacement. Most patients can bear weight on their knee, either with assistance or independently, on the same day as their surgery. Some patients are able to return to their normal activities within three to six weeks.

“Seeing my patients recover after joint replacement surgeries, especially after a short recovery time, is truly rewarding. Knowing that their freedom of movement is no longer limited is a true joy.”
