Preoperative Positioning and Socket-Anchor Technique for Arthroscopic Medial Patellofemoral Ligament Reconstruction Using Allograft Tendon.

ABSTRACT: Accurate positioning of the femoral insertion of the medial patellofemoral ligament (MPFL) is the main difficulty in MPFL reconstruction. This article describes an all-arthroscopic MPFL reconstruction procedure. Preoperative 3-dimensional computed tomography assists in MPFL patellar and femoral insertion positioning, with arthroscopic reconfirmation of femoral insertion positioning through a subcutaneous tunnel during surgery. In the socket-anchor technique for patellar insertion fixation, a 10-mm-deep bone tunnel (socket) is created along a previously located guide pin at the MPFL patellar insertion; then, an absorbable suture anchor is inserted into the end of the socket to fix the tendon graft. This technique provides the advantages of being minimally invasive, yielding accurate positio
