Patients
Between November 1994 and July 1996, the senior author (D.D.) performed reconstruction or repair of the medial patellofemoral ligament in the treatment of patellar dislocation in 19 knees in 19 patients. Fifteen of these patients were available for evaluation, which consisted of a questionnaire, 2 standard knee scores, physical examination, and radiographic imaging at a minimum of 2 years postoperatively. The remaining 4 patients could not be located. The patient population is summarized in

Discussion
Many authors have described the anatomy of the medial aspect of the knee joint.10, 16, 17, 18 Warren and Marshall16 described the location of the medial patellofemoral ligament in layer II of the medial side of the knee, with its origin at the adductor tubercle and its insertion at the superomedial border of the patella, the undersurface of the vastus medialis obliquus, and the aponeurosis of the vastus intermedius. Feller et al.18 have shown its anatomic consistency in 20 cadaveric
