© 2017 Elsevier Inc. Residual rotational laxity following anterior cruciate ligament (ACL) reconstruction has been identified as significant concern in many patients, despite evolution of techniques. The expanding body of knowledge on the anatomy and biomechanics of the anterolateral soft tissue restraints in rotational control of the knee has reignited an interest in extra-articular reconstruction techniques for augmenting ACL reconstruction. Reconstruction techniques currently used can be broadly categorized as either lateral extra-articular tenodesis or reconstruction of the anterolateral ligament. In this article, we outline the relevant anatomy, biomechanics, and rationale behind the indications and technique of our current extra-articular augmentation procedure.
