Abstract:
A posterior tibial slope (PTS) greater than 12° is an established risk factor for anterior cruciate ligament graft reconstruction failure. Reducing PTS is thus considered protective to the anterior cruciate ligament graft, and it can be achieved through an anterior closing-wedge osteotomy. Prior to the procedure, PTS should be accurately measured to determine the amount of correction that is needed. Radiographic films remain the gold standard for measuring PTS. The purpose of this presentation is to show validated and reproducible step-by-step techniques for measuring PTS and anterior tibial translation for anterior closing-wedge osteotomy using monopedal full-length weight-bearing tibia standing radiographs.
