Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Instability
The medial patellofemoral ligament (MPFL) is the most important passive soft-tissue restraint to lateral patellar instability. It has been shown both clinically and radiographically that the MPFL tears when the patella dislocates. The other crucial stabilizing components of the knee extensor mechanism are the bony restraints (especially the lateral trochlear ridge) and the dynamic softtissue restraints (especially the vastus medialis obliquus). MPFL reconstruction is one of a large number of different surgical procedures that have been described to restore patellar stability. Studies reporting short-term and midterm results of MPFL reconstruction confirm excellent patient satisfaction and low recurrent instability rates. Sometimes other procedures are better suited to addressing the pathoanatomy. For example, patients with excessive tibial tuberosity lateralization may need a medializing tibial tuberosity osteotomy, and patients with extreme patella alta may need a distalizing osteotomy.
