Imagerie par résonance magnétique des lésions méniscoligamentaires du genou

Abstract

Accuracy of MRI in knee disorders is now well established, especially in menisci or ligamentous tears. During the past decade, significant advances were made in diagnostic criteria, pitfalls and limitations. After reviewing technical considerations of performing routine explorations of a traumatic knee, we review imaging and diagnostic difficulties of menisci lesions. Next we describe anterior and posterior cruciate ligament tears, and review their direct and indirect signs. Finally, we tackle injuries of the medial and lateral supporting structures of the knee.
