Anterior cruciate ligament(ACL) reconstruction of the knee is associated with a certain risk of failure, and the failure rate is higher in high-risk patients. With the discovery and recognition of roles of anterolateral structure(ALS) in maintaining the rotation stability in normal knee, it is possible to augment or reconstruct ALS in combination with ACL reconstruction to reduce the failure rate in the patients with high-risk factors for ACL injuries. Therefore, on the basis of evidence-based medicine, the expert group summarized and discussed literature on the definition, preoperative evaluation, surgical indications, surgical techniques and strategies, principles in postoperative rehabilitation, and prevention and management of complications for the ALS of knee, and developed this consensus. The proposed consensus will provide physicians with a complete set of clinical routines and pathways for the diagnosis and managment in selecting ALS augmentation or reconstruction when performing ACL reconstruction in the patients with high risks of failure and revision surgeries.
