Video Summary

The speaker discusses the rediscovery of the anterolateral ligament (ALL) related to knee stability, particularly in ACL injuries. While the ALL concept has gained mainstream attention, its anatomy is inconsistent and debated, and the ligament's exact functional role remains unclear. Extra-articular reconstructions can improve stability but may cause stiffness and arthritis. Biomechanical studies suggest the lateral knee structures act as a functional unit, not just a single ligament. Clinical outcomes show potential benefit but risks of over-constraint exist. The speaker cautions against premature adoption due to uncertain anatomy, conflicting evidence, additional costs, and potential industry bias.
