Anchor-Free Minimally Invasive Double-Bundle Medial Patellofemoral Ligament Reconstruction With Medial Retinacular Tightening for the Treatment of Recurrent Patella Dislocation.

Recurrent patella dislocation is a common orthopaedic condition in adolescents, with medial patellofemoral ligament injuries found in most cases. Double-bundle anatomic medial patellofemoral ligament reconstruction (MPFLR) has been widely used for managing patellofemoral instability. However, traditional MPFLR uses suture anchors for graft fixation, which requires a 3- to 5-cm medial incision. In addition, potential suture anchor pullout and injury to the extensor mechanism may delay postoperative recovery and increase the risk of recurrent dislocation. In this article, we propose an anchor-free double-bundle anatomic MPFLR technique. This approach uses high-strength sutures for transosseous fixation and achieves medial retinacular tightening under arthroscopy. The preservation of extensor mechanism minimizes postoperative pain and promotes faster rehabilitation.
