The medial patellofemoral ligament (MPFL) is the most important factor for stabilizing the patella and preventing lateral patellar dislocation. Medial patellofemoral ligament reconstruction is an accepted surgical technique to restore patellofemoral stability after lateral patellar dislocation. The authors recently developed a new anatomical MPFL reconstruction method using a cylindrical bone plug and grafted semitendinosus tendon at the anatomical femoral attachment site to mimic the native MPFL. This study evaluated the new technique for stabilizing recurrent patellar dislocation. ⋯ This study demonstrated excellent results using the new procedure for recurrent dislocation of the patella, with instability in only 1 of 31 knees (3.2%).
