Partial knee replacement, also known as unicompartmental knee replacement (Uni Knee), is a less invasive alternative to total knee replacement for patients with damage confined to a single compartment of the knee joint.

This procedure is ideal for patients whose arthritis or joint damage affects only one side of the knee, leaving the other compartments intact. By targeting only the affected area, the surgery preserves more of the natural knee structure, resulting in quicker recovery, reduced postoperative pain, and better knee function compared to total knee replacement.

During the surgery, the damaged cartilage and bone are removed from the affected compartment and replaced with a prosthetic implant, which is typically made of metal or plastic. This approach allows for a more natural feeling in the knee after recovery.
