Partial Knee Replacement

Partial knee replacement, also known as unicompartmental knee arthroplasty, is a surgical procedure in which only the damaged or diseased part of the knee joint is replaced with an artificial implant. This is in contrast to a total knee replacement, where the entire knee joint is replaced. The knee is divided into three compartments: medial (inside), lateral (outside), and patellofemoral (front). In a partial knee replacement, only one of these compartments is replaced.

Indications for Partial Knee Replacement:
Osteoarthritis:

• When arthritis primarily affects one compartment of the knee, often the medial compartment.

Post-Traumatic Arthritis:

• Arthritis that develops after a specific injury to the knee joint.

Inflammatory Arthritis:

• Inflammation of the knee joint due to conditions like rheumatoid arthritis.

Limited Joint Involvement:

• When only one compartment of the knee is affected, leaving the other compartments relatively healthy.

While partial knee replacement can provide excellent results for the right candidates, long-term outcomes may vary, and some patients may eventually require conversion to a total knee replacement.
Surgeon Expertise:

The success of the procedure often depends on the surgeon's expertise in patient selection, surgical technique, and implant positioning.
Partial knee replacement is a well-established and effective treatment option for select patients with localized knee arthritis. It is important for individuals considering this procedure to have a thorough discussion with their orthopedic surgeon to understand the potential benefits and risks based on their specific condition.
