[Sonographic images of meniscus lesions]

The various types of meniscal lesion including longitudinal, horizontal and transverse tears, bucket handle tears (displaced or non-displaced) as well as tears of the meniscus base can be visualized in differing sonographic views. Our results on 39 patients, whom we sonographed and then controlled operatively, show that the different meniscal lesions are not reliably differentiated by ultrasound. Depending on the view chosen, similar sonographic displays result for all of the lesions under discussion. Only a smooth reflecting plane in the otherwise homogeneous structure of the meniscus is proof of the existence of a meniscal lesion.
