Abstract
An AMZ tibial tuberosity transfer system and method of treatment of patellofemoral joints. The AMZ system includes 1) a retractor with a better conformation to anatomy and more curve (not just a bend), and also with a larger radius on the front of the retractor to allow for easier insertion; 2) a cutting block that can fully accept a collared pin; 3) a rod preferably formed of stainless steel; 4) a tuberosity pin guide; 5) an exit indicator that engages tightly the cutting block so there is no slope on exit indication; and 6) a horizontal bar provided with markings to measure the medial shift.
