Medial patellofemoral ligament reconstruction using dual patella docking technique

Introduction: Medial patellofemoral ligament (MPFL) injuries are common in children and young adults. Patellar dislocation is the complete displacement of the patella from the trochlear groove of the femur. It nearly always involves a lateral displacement and commonly occurs during sports. Current techniques of medial patellofemoral ligament (MPFL) reconstruction vary with respect to methods of fixation on the femur and the patella. In patients with recurrent patellar dislocations with normal lower-extremity alignment, anatomic reconstruction of the MPFL has been shown to restore patellar stability. We describe a technique that creates an anatomic reconstruction using a dual docking technique into the patella. Our technique is simple and efficacious for reconstructing the MPFL without implant fixation in the patella, allowing a maximal bone-tendon interface for healing. Results: It provided anatomic reconstruction, not reliant on implants in patella, Docking technique allows greater surface area for graft-to-bone contact. Discussion: The orthopedic literature is replete with techniques for the management of patella instability. These techniques include proximal soft-tissue procedures, distal osseous realignment procedures, and combinations of both. We are using Dual Patella docking technique here.
