The purpose of this study was to identify the relationship between different movement strategies during 90° cutting maneuvers and the free (reaction) moment. It is observed that the orientation of either a positive or negative free moment is generated by different orientations of the foot segment at initial touch down. These finding impacted the rotational moment that is transferred to the knee joint: A higher internal reaction moment is observed when athletes are exposed to a positive free reaction moment, which potentially increases load on the ACL. The most important finding was that it is possible to generate differently orientated reaction moments during the same movement, which highlights the importance of investigating movement strategies in order to understand potential injury risk factors.
