Medial patellofemoral ligament reconstruction has gained in popularity over the past 15 years, with most studies showing a clear advantage over techniques such as medial patellofemoral ligament (MPFL) repair or medial imbrication for the treatment of patellar instability. A debate continues as to the type of fixation on the patella, tunnel versus suture anchor, as well as the number of fixation points. In fact, some senior patellofemoral surgeons have opted away from patellar bony fixation altogether to avoid complications associated with patellar fixation such as fracture or penetration of the articular cartilage.
To Minimize Complications, Bone Tunnels Should Be Avoided
In my practice, I prefer to use 2 all-suture suture anchors for patellar fixation as there is minimal risk of fracture or significant cartilage damage compared with tunnel drilling or placement of larger suture anchors. The graft choice for MPFL reconstruction has been shown to be relatively unimportant, and for this reason, I typically choose gracilis allograft to avoid graft-site morbidity and hamstring weakness.
