title: MR imaging of anterior cruciate ligament injuries.
abstract: MR imaging has become the imaging modality of choice to evaluate the integrity of the anterior cruciate ligament (ACL). This article discusses the normal anatomy of the ACL and the clinical diagnosis of ACL disruption. The MR imaging appearance of chronic and acute ACL injuries, and the relative value of primary and secondary signs in injury diagnosis are reviewed. The clinical value of MR imaging in the evaluation of the ACL-deficient knee is also discussed.
