The medial patellofemoral ligament (MPFL) has been identified as the primary medial restraint to prevent lateral patellar displacement; it contributes up to 80% of the medial restraining forces on the patella1,2. Anatomically, the MPFL originates from the superior two-thirds of the medial patellar border and runs posteriorly toward the medial femoral epicondyle to insert in close relation to the origin of the superficial medial collateral ligament and slightly distal to the adductor tubercle3-5. Several techniques of MPFL repair and reconstruction have been described, with various graft options, tunnel placements, and fixation options, with or without concomitant procedures such as lateral retinacular release or tibial tuberosity osteotomy. Most techniques for patellar attachment of a reconstructed MPFL use patellar tunnels6-8, while some use suture anchors or soft-tissue fixation7,9,10.
