Abstract
Many surgical techniques have been reported for the treatment of malalignment of patella. Over recent years, as the medial patellofemoral ligament (MPFL) has been shown to be the primary restraint to lateral patellar translation, MPFL reconstruction has become a common procedure. The purpose of this study was to investigate the short term results of 8 cases (4 men, 4 women, mean age 22.8 years), who underwent MPFL reconstruction in our hospital using hamstring tendons. Mean follow-up period was 1.7 years. The mean Kujala score improved from preoperative 55.6 points to postoperative 95.5 points, with no occurrence of patella apprehension. Furthermore, patellofemoral alignment improved after surgery in all cases. Based on these results, we concluded that MPFL reconstruction is useful for the treatment of patella malalignment.
