Medial Patellar Ligament Reconstruction Using Peroneus Longus Tendon Autograft for Recurrent Patellar Dislocation-Patellar Instability.

Medial patellofemoral ligament reconstruction is a common treatment for recurrent patellar dislocation, with long-term follow-up data showing favorable clinical outcomes and high patient satisfaction. Younger female patients, who represent the primary affected population, often prefer minimally invasive surgical incisions, particularly those with keloid-prone skin. In this study, the authors describe a technique for reconstructing the medial patellofemoral ligament by obtaining half of the peroneus longus tendon autograft through a small incision. This approach preserves the function of the peroneus longus muscle and provides good clinical outcomes while minimizing surgical scarring.
