📌 Complete MPFL Tear at Femoral Origin
- Lateral patellar dislocation often involves the medial patellofemoral ligament (MPFL), which has its weakest attachment at the femoral side.
- The patellar insertion of the MPFL is much wider and reinforced by the vastus medialis obliquus muscle, medial retinaculum, and the vastus intermedius tendon.
- The femoral origin is the most common site of injury, which often results in a decreased likelihood of returning to pre-injury activity levels.
