Hybrid 2-Point Suture Anchor Technique for Patellar Fixation in Medial Patellofemoral Ligament Reconstruction

Several techniques for patellar fixation for reconstruction of the medial patellofemoral ligament (MPFL) have been described in the literature. Despite the success of MPFL reconstruction reported in the literature, there is insufficient evidence to recommend a standard method of patellar fixation. A hybrid 2-point fixation technique allows for increased contact area and contact pressure between the insertion of the graft and the patella and offers a broad insertion of the graft onto the width of the patella, thus allowing for a more native attachment site to be re-created. The technique involves 2 suture anchors to increase graft compression onto the patella. This construct increases the primary load to failure of the repair, increases the surface contact area, and increases the stability of the MPFL reconstruction. These mechanical advantages decrease the chance of recurrent patellar instability and the chance of patellar fracture by avoiding transpatellar fixation.
