title: The figure-of-four view to evaluate ACL injury.
abstract: Standard arthroscopic assessment of the anterior cruciate ligament (ACL) injury through an anterior view can be sub-optimal for evaluation of the femoral origin, particularly the posterior component. The figure-of-four view provides increased exposure to the posterolateral aspect of the intercondylar notch, thereby facilitating diagnosis of proximal ACL injury and avulsions of the ACL origin.
