Abstract
The medial patellofemoral ligament (MPFL) and the MPFL/vastus medialis obliquus complex are essential for patellar stability. Insufficiency of the MPFL can lead to altered biomechanics and patellofemoral joint contact pressure, high recurrence rate, osteochondral lesions, compromised knee function, and patellofemoral osteoarthritis. Most frequently surgical reconstruction of the MPFL is performed to address patellar instability; however, open physis and donor site morbidity can be a concern. This Technical Note presents a surgical technique to identify the insufficient MPFL and describes in detail an anatomical retensioning repair of the MPFL to restore patellar stability.
