Partial Knee Replacement Surgery

Knee pain from arthritis can be particularly debilitating because we use our knees in almost all of our daily activities. If you are experiencing severe knee pain that interferes with your normal functioning, your doctor may recommend a partial knee replacement, also known as uni-compartmental knee replacement.

The knee can be divided into three compartments: the medial compartment, the lateral compartment, and the patello-femoral compartment. The uni-compartmental implant is designed to replace either the medial or lateral compartment.

Available Treatment Options
Your doctor may try several conservative treatments before recommending partial knee replacement.

If the conservative treatments do not relieve your pain from arthritis of the knee, surgical procedures may be recommended. Arthroscopic surgery is a minimally invasive procedure to remove debris or repair torn cartilage. Total knee replacement surgery is major surgery that replaces all three compartments of the knee. Between those two alternatives is uni-compartmental surgery.
