Sonographie des Meniskus und seiner Läsionen

It is the considered opinion of the authors that meniscus sonography can largely replace arthrography. This opinion is based on their detailed examinations and studies. Sonographic visualisation of all lesions produced by a scalpel was demonstrated using knees of corpses. Even cracks having the fineness of a human hair were visualised by sonography. A comparison between sonographic and surgical findings in meniscus lesion yielded in 82 patients an agreement of 95.1%. In 47 patients it was possible to prove that sonography was more accurate than arthrography as far as diagnosis was concerned. A comparison of 94 sonographically and arthrographically established findings yielded agreement in 89% of the cases. Sonography is suitable for meniscus imaging especially on account of the good imaging reproducibility of meniscus morphology; through safe detection of a pathological process in the meniscus; through the safe presentation of lesions; through the accurate imaging of all parts of the meniscus; and, furthermore, through the invaluable advantage of noninvasiveness, freedom from pain and hazards; and, last but not least, rapid manipulation and unlimited repeatability.
