All-Arthroscopic Reconstruction of the Medial Patellofemoral Ligament Using Artificial Ligament for Recurrent Patellar Dislocation.

ABSTRACT: Medial patellofemoral ligament injury is the primary stability barrier after patellar dislocation, with high recurrence rates with conservative treatment, making reconstruction surgery increasingly mainstream. This article describes an all-arthroscopic technique for medial patellofemoral ligament reconstruction using high-strength synthetic suture tape combined with suture anchors, eliminating the need for tendon harvesting. It involves anatomic localization of the patellar and femoral insertion sites, with appropriate tensioning and fixation at 30° of knee flexion to restore medial stability. This method shortens operative time and avoids donor-site complications (e.g. neurovascular injury, hematoma, and pain) and patellar fracture risks. Biomechanical studies show that the tensile streng
