Abstract
Anterior cruciate ligament (ACL) tears are a common orthopaedic injury, particularly in athletic populations. Primary ACL
reconstructions (ACLR) have fairly successful outcomes; however, there is a subset of patients who experience failure
or re-injury and require a technically challenging revision ACLR procedure. Knowledge of the clinically relevant ACL
anatomy and biomechanics, including closely associated meniscal, ligament, and osseous structures, is fundamental
for an anatomic revision ACLR. Comprehensive evaluation and diagnosis are also critical to identify the causes of
primary ACLR failure and determine appropriate treatment(s). Although outcomes have improved over time, revision
ACLR patients still experience sub-optimal outcomes compared to primary ACLR patients. This review will highlight the
current concepts of anatomy, biomechanics, clinical evaluation, treatment, outcomes, and post-operative rehabilitation
to optimize outcomes for revision ACLR procedures.
