Abstract
BACKGROUND: The clinical outcome of the medial patellofemoral ligament reconstruction (MPFLR) based on graft length change pattern (length pattern group) was compared with MPFLR based on visual examination combined with palpation (visual/palpation group). METHODS: Physical findings, patient-reported outcome, and radiographic demonstration were evaluated pre- and postoperatively. RESULTS: The length pattern group had significantly lower risk of a positive apprehension test (Odds ratio 0.12, p < 0.01), and higher scores in postoperative Lysholm score (p = 0.046) and patient satisfaction (p = 0.036) than The visual/palpation group. CONCLUSION: MPFLR based on graft length change pattern improved on patient-reported outcomes and apprehension test. LEVEL OF EVIDENCE: Level Ⅲ, Retrospective comparative study.
