[Meniscus sonography--alternative to invasive meniscus diagnosis?].

Sonographic visualization of the meniscus as well as the detection and evaluation of its lesions presupposes use of the 7.5 MHz transducer of a sector scan. All lesions applied by means of a scalpel to cadaver knees could be pictured and evaluated in this way. In a clinical study, there was agreement between sonographic and surgical findings in 86 out of 91 patients (94%). The arthrography carried out in addition in 50 of these patients had a lower precision (88%) than sonography (98%). Agreement between the results of sonography and arthrography was found in 87 out of 98 patients (89%). The complete freedom from risk and high precision support the application of sonography in diagnosis of meniscus lesions. It can thus replace arthrography in this indication.
