The anterolateral ligament (ALL) has been identified as a supporter to the anterolateral rotational stability of the knee joint, and it has a strong association with ACL ruptures. [4][5][6] Ferretti et al. [7] reported that approximately 90% of ALL injuries are associated with ACL tears, and due to this strong relationship, recent studies have focused on clearly demonstrating the biomechanical and anatomical features of the ALL. In a recent biomechanical study, Nitri et al. [8] reported that concurrent ACL reconstruction and ALL reconstruction significantly improve the rotatory stability of the knee compared with ACL reconstruction only.
