This technique video demonstrates medial patellofemoral ligament (MPFL) reconstruction using a partial thickness quadriceps tendon graft. We’ve performed this procedure since 1998 and described the technique in 2005. We’ve been very pleased with the results. It’s a very simple technique in that you only have to detach and attach one side of the graft. The quadriceps tendon remains attached to the patella. It’s a flat, ribbon-like graft much like the native MPFL. It avoids patellar tunnels which are risks for fractures. We simply dissect and detach the graft proximally, rotate the graft, and attach it to the femur. In this manner, it lies along the course of the normal MPFL.
