Minimally invasive “crescentic” imbrication of the medial patellofemoral ligament for chronic patellar subluxation

Chronic patellar subluxation is one of the many causes of anterior knee pain. Nonoperative management of this disorder is successful in many patients, but surgical intervention may be necessary for refractory cases. We present a surgical technique for chronic patellar subluxation that is minimally invasive and is focused specifically on the medial patellofemoral ligament.
