Summary

Sonography of the knee has gained in significance in the diagnosis of the meniscus; experimental and clinical studies have demonstrated that the normal and pathological anatomy of the meniscus can be visualized on a sonogram. The aim of this comparative investigation is to evaluate sonographic lesion diagnosis in comparison with arthroscopic findings, using a standardized examination method. Two hundred and six knee joints were first scanned sonographically using a 7.5 MHz sector transducer. The examining doctor had neither anamnestic nor clinical information in advance. On the following day, the joints were examined arthroscopically, without the findings of the day before being available to the examiner. When the findings were compared, the sensitivity of sonographic diagnosis of lesions was found to be 82.2% and its specificity 87.6%. The patients were of varying ages and had varying anamneses. The results show that sonography of the meniscus is a valuable diagnostic help when the knee-joint symptoms are not clear, given that the correct technical equipment and sufficient experience with this form of examination are at hand. The advantage of sonography is that, in contrast to arthroscopy, it is noninvasive and easily available.
