Medial Patellofemoral Ligament/Medial Quadriceps Tendon Femoral Ligament (MPFL/MQTFL) Reconstruction With Double-Bundle Semitendinosus Allograft

Background: Patellofemoral instability is a common condition that is associated with significant long-term morbidity. Indications: Persistent patellofemoral instability following a trial of nonoperative management. Technique Description: Combined medial patellofemoral ligament and medial quadriceps tendon femoral ligament (MPFL/MQTFL) reconstruction with double-bundle semitendinosus allograft. Results: In a consecutive series of 142 patients with a minimum 2-year follow-up, failure rate was 7.7%. Patients had improved functional outcomes, as compared to those who underwent nonoperative management. Discussion/Conclusion: MPFL/MQTFL reconstruction is an operative solution to patellofemoral instability, which yields decreased rates of re-dislocation and improved patient functional outcomes. This technique also has the capacity to restore native anatomy and prevent the development of osteoarthritis over time.
