Abstract
Revision ACL surgery is indicated in patient who presented with pathologic anterior laxity on clinical examination that reproduces their symptoms of instability during activities of daily living or athletic activities or patient with stable but stiff and painful knee with limited range of motion.The goals of the revision ACL surgery are to stabilize the knee, prevent further injury to the articular cartilage and menisci, and maximize the patient’s function.
Successful revision ACL surgery requires a thorough preoperative evaluation, include adetailed history,physical examination,and radiographic evaluation. preoperative planning begins with a determination of the site and the size of the old tunnel and the presence of any other factors is the first step in a carefully- constructed treatment plan, which includes consideration of skin incision to be used, methods of graft removal, hardware removal, the need for a staged procedure or concomitant surgery, graft material selection, tunnel placement, graft fixation, and postoperative rehabilitation protocol. Despite the most meticulous planning unanticipated findings may be encountered in the operating room, and the preoperative plan should have enough flexibility to accommodate these developments.
