[The value of nuclear magnetic resonance tomography in diseases of the knee joint]

Abstract

In a prospective study we examined 107 patients suffering from an acute trauma or a chronic disease of the knee joint by MRI. The MRI results were compared to the results of arthroscopy. Normal anatomical structures can be differentiated and there is a high diagnostic reliability for lesions of the medial (accuracy: 91%, predictive value: 84%) and lateral (accuracy: 93%, predictive value: 79%) meniscus, complete tears of the anterior cruciate ligament (accuracy: 93%, predictive value: 75%), chondropathia of the patella, and osteochondritis dissecans. Partial ruptures of the ACL as well as small cartilage defects could usually not be demonstrated.
