It has been proposed that the ALL assists the ACL as a stabilizer against internal rotation and anterior tibial translation, thus reducing anterolateral rotatory instability (ALRI). However, because of variability in anatomic descriptions, authors have proposed different ALL reconstruction techniques, specifically involving different femoral attachment positions. Renewed concerns have been raised, because biomechanical studies have suggested that this procedure can over- constrain internal rotation. Given the relative paucity of literature reviewing the techniques, biomechanics, and outcomes of ALL reconstructions, the purpose of this study was to perform a systematic review of the described ALL reconstruction techniques, biomechanical performance, and clinical outcomes of ALL reconstruction in the setting of concurrent ACL reconstruction. We hypothesized that there would be inconsistency in techniques and therefore biomechanical characteristics, as well as a relative paucity of clinical outcomes studies.
