Partial Knee Replacement: Success Rates and What to Expect

Partial knee replacement, also known as unicompartmental knee arthroplasty, is a surgical procedure that replaces only the damaged part of the knee joint. This minimally invasive approach is often considered for patients with osteoarthritis affecting only one compartment of the knee. But how successful is this procedure? Let's delve into the success rates, factors affecting outcomes, and what you can expect after a partial knee replacement.

Success Rates: A Look at the Numbers

Studies have shown that partial knee replacement is a highly successful procedure, with many patients experiencing significant pain relief and improved mobility. According to a study published in the Journal of Bone and Joint Surgery, the 10-year survival rate for a partial knee replacement is 90% (1).

Factors Influencing Success

Several factors can influence the success of a partial knee replacement, including:

• The severity of osteoarthritis: Patients with less severe osteoarthritis, particularly those with damage only in the medial compartment of the knee, tend to have better outcomes.
• Patient health and activity level: Patients who are healthy and active before surgery are more likely to recover well and benefit from the procedure.
• Surgical technique: The skill and experience of the surgeon play a crucial role in the success of the procedure.
• Post-operative rehabilitation: Following a strict rehabilitation program is essential for regaining full function and minimizing the risk of complications.

What to Expect After Surgery

• Pain Relief: Most patients experience significant pain relief after the procedure.
• Improved Mobility: Partial knee replacement improves range of motion and allows for greater flexibility in the knee.
• Increased Activity Levels: Patients are often able to return to their desired activities, including walking, running, and even playing sports.
• Recovery Time: Recovery from partial knee replacement is typically shorter than from a total knee replacement, with patients often able to resume normal activities within a few months.

Potential Risks and Complications

While generally safe, partial knee replacement, like any surgery, carries potential risks and complications, such as:

• Infection: Infection is a rare but serious complication that can lead to delayed healing and further surgery.
• Blood clots: Deep vein thrombosis (DVT) is a potential complication that can occur after surgery.
• Loosening or wear: Over time, the implant may loosen or wear down, requiring revision surgery.
• Stiffness: Stiffness is a common complication, but it can usually be managed with physiotherapy.

Choosing the Right Procedure

Deciding whether partial knee replacement is right for you requires a comprehensive evaluation by an orthopedic surgeon. They will assess your specific situation, including the severity of your arthritis, your overall health, and your activity level.
