Medial Patellofemoral Ligament Reconstruction: Docking Technique

The management of patellar instability has advanced with an improved understanding of the critical role of the medial patellofemoral ligament (MPFL), along with the development of novel techniques for ligament reconstruction. The docking technique for MPFL reconstruction offers several technical advantages, including anatomically accurate reconstruction, ease of confirmation of graft isometry, and simplicity of graft tensioning and fixation. Biomechanically, the femoral fixation provides a combined interference screw and suture anchor construct. Imbrication of the vastus medialis obliquus (VMO) and medial retinaculum contributes additional dynamic support to the medial soft-tissue reconstruction. The docking technique offers a simplified and accurate approach to MPFL reconstruction, with consistently favorable postoperative results in the management of patellar instability.
