Medial patellofemoral ligament reconstruction and repair for lateral patellar instability

The medial patellofemoral ligament (MPFL) is the primary soft tissue restraint to lateral patellar translation. The MPFL is often injured with a first time lateral patellar dislocation. Rehabilitation is the mainstay of treatment, however, recurrent patellar instability results in substantial morbidity in active individuals. MPFL reconstruction has become the cornerstone of surgical stabilization of the patella for recurrent lateral patellar dislocations. Although techniques for MPFL reconstruction vary, adherence to biomechanical and anatomic principles is necessary for optimal outcome. Compliance with postoperative rehabilitation protocol is important for optimal recovery and return to activity.
