Lateral Extra-Articular Procedures_ When or Ever Should They be Used with an ACLR

Video Transcription

Video Summary

Brian Colelli discusses lateral extra-articular procedures (LAT) in ACL reconstruction, reviewing anatomy, biomechanics, and clinical evidence. The anterolateral ligament (ALL) and associated structures serve as secondary rotatory stabilizers. Clinical studies show LAT combined with ACL reconstruction reduces graft failure rates, especially in high-risk groups like young athletes, patients with high-grade pivot shift, revisions, or ligament laxity. Biomechanical data suggest the IT band plays a primary role, with LAT procedures improving stability in select cases. While current evidence supports LAT's benefits in specific indications, further high-quality trials are needed to clarify long-term outcomes and risks of knee over-constraint.
