Abstract
Metal interference screw fixation has become the gold standard fixation method for bone patellar tendon bone anterior cruciate ligament (ACL) reconstruction. Clinical outcomes studies as well as biomechanical pullout and cyclic loading studies have supported the interference screw's ability to provide stability during the postoperative period of graft incorporation. In the event that revision ACL surgery is required, interference screws can be left in and circumvented or removed with a variety of reverse cutting threads and trephines. They can then be replaced with extra-wide revision screws or double-screw fixation techniques. In this article, we will detail the metal interference screws commercially available for use in ACL reconstruction, insertion of these screws, and removal methods.
