Post-operative schematic diagram of the knee joint. (A) Diagram in the absence of the VMO: The MPFL graft is depicted as being reflected medially and looped around the AMT near its insertion. (B) Diagram depicting the MPFL graft (green color) and its relationship to the native MQTFL (yellow color) and the native MPFL (blue color). (C) Diagram in the presence of VMO showing the MPFL graft as being passed deep to the VMO; the pink lines represent the sites of sutures (at the anterior surface of the patella and at the femoral origin, which is distal and anterior to the AT). QT, Quadriceps Tendon; MQTFL, Medial Quadriceps Tendon Femoral Ligament; MPFL, Medial Patellofemoral Ligament; PT, Patellar Tendon; VMO, Vastus Medialis Obliquus; AMT, Adductor Magnus Tendon; LCL, Lateral Collateral Ligament; SMCL, Superficial Medial Collateral Ligament
