Introduction

The anterior cruciate ligament (ACL) is composed of the anteromedial and posterolateral bundles [1, 2]. Although these two bundles are closely aligned anatomically, they do have distinct biomechanical functions with the anteromedial bundle stabilizing the knee in flexion and the posterolateral bundle stabilizing the knee in extension [1, 2, 3, 4, 5].

Most ACL tears are complete with the tear extending across both bundles. Partial tears of the ACL are less frequently encountered and may involve both bundles to a similar degree or one bundle predominantly. Although complete ACL tears do not have the capacity to heal, a limited blood supply to the ACL via the medial geniculate artery does allow healing of partial tears [6, 7]. Correct assessment regarding the presence, severity, and location of partial tears is relevant since delayed recognition of a partial tear can result in progression to complete tear [6]. Also, if only one bundle is predominantly torn, isolated single...
