Bicompartmental Knee Arthroplasty Using a Monolithic Implant Design

Traditional total knee arthroplasty is a safe and effective surgical procedure that has been performed successfully for >40 years. However, it does not seem to be the most appropriate treatment option for patients with only partial arthritis of the knee. The efficacy of unicompartmental knee arthroplasty has been established, but only during cases in which disease is limited to either the medial or lateral compartments. As arthritis progresses to the patellofemoral joint, there is considerably less consensus as to the most effective surgical treatment. A promising option is bicompartmental knee arthroplasty using a monolithic implant design. The current procedure may improve patient outcomes by resurfacing the diseased portions of the knee and sparing healthy articular tissue and the cruciate-ligaments, while simultaneously reducing surgical cost.
