CT demonstration of capsuloligamentous lesions of the knee joint

Direct CT of the knee joint was performed on 45 patients who subsequently underwent surgery for clinically suspected capsuloligamentous lesions. It was possible to perform a complete examination on all patients, even those immobilized in a cast or with acute clinical symptoms. Computed tomography correctly differentiated 32 lesions of the anterior cruciate ligament, five lesions of the posterior cruciate ligament, 16 lesions of the collateral ligaments, and 43 associated meniscal lesions. In five cases surgery disproved the CT diagnosis. Our experience permitted us to identify direct CT signs that not only indicate the presence of a capsuloligamentous lesion but also determine its site, extent, and seriousness.
