Background. The purpose of this study was to compare outcomes of medial patellofemoral ligament (MPFL) repair or\nreconstruction. Methods. Fourteen knees that underwent MPFL repair and nine (F5, M4) knees that underwent reconstruction\nat our institution were evaluated for objective and subjective outcomes.Themean age at operation was 20.1 years for repair and 19.8\nyears for reconstruction. All patients had a minimum of 2 years of follow-up (range: 24ââ?¬â??75 months). Patient subjective outcomes\nwere obtained using the International Knee Documentation Committee (IKDC) and Kujala patellofemoral subjective evaluations,\nas well as Visual Analog (VAS) and Tegner Activity Scales. Bilateral isometric quadriceps strength and vastus medialis obliquus\n(VMO) and vastus lateralis (VL) surface EMG were measured during maximal isometric quadriceps contractions at 30Ã?° and 60Ã?° of\nflexion. Results.There were no redislocations in either group. There was no difference in IKDC (P = 0.16), Kujala (P = 0.43), Tegner\n(P = 0.12), orVAS (P = 0.05) scores at follow-up. Therewere no differences between repair and reconstruction in torque generation\nof the involved side at 30Ã?° P = 0.96) and 60Ã?° (P = 0.99). In addition, there was no side to side difference in torque generation or\nsurface EMG activation of VL or VMO. Conclusions. There were minimal differences found between patients undergoing MPFL\nrepair and MPFL reconstruction for the objective and subjective evaluations in this study.
