Injuries of the anterior cruciate ligament (ACL) represent one of the most common sports injuries, whereby reconstruction of the anterior cruciate ligament (ACL-R) is associated with good to excellent clinical results. In addition to psychological factors, such as psychological readiness, persistent rotatory knee instability is described as the most common reason for delayed or failure to return to sports. Persistent anterolateral rotatory instability (ALRI), which can occur in up to 15% of cases after ACL-R, is associated with worse clinical outcomes, functional instability and the potential development of secondary cartilage lesions and even osteoarthritis; however, validated biomechanical and clinical studies have demonstrated that surgical techniques to stabilize the anterolateral complex can restore the kinematics of the knee joint in ALRI. The indications for an additional anterolateral stabilization procedure are still not clearly defined and remain controversial, especially in the primary intervention. The purpose of this article is to review and discuss the borderline indications based on the authors' experience.     «
