Technical notesMinimally invasive “crescentic” imbrication of the medial patellofemoral ligament for chronic patellar subluxation
Section snippets
Surgical technique
A tourniquet is applied to the thigh, and the leg is prepped and draped in the usual sterile manner. The leg is exsanguinated and the tourniquet is inflated. Routine arthroscopy of the knee is performed and a lateral retinacular release is completed either arthroscopically or through a small lateral incision. A 3-cm longitudinal skin incision, starting at approximately the level of the superior pole of the patella and extending distally, is placed 1 cm medial to the medial border of the patella
Discussion
The MPFL is located in layer 2 of the medial aspect of the knee. It originates from the anterior aspect of the medial epicondyle of the femur, immediately superior to the femoral attachment of the superficial MCL. The main insertion of the MPFL is the superior medial aspect of the patella. 1, 2, 12, 13, 14 Biomechanical studies have shown that the MPFL is the major restraint to lateral patellar translation. 1, 2
The primary pathoanatomy associated with acute lateral patellar dislocation is
