[Possibilities and limitations of knee joint sonography]

In case of arthrosonography the sonography of knee-joint has got more importance because of the prompt and reproduceable possibility of soft tissue imaging without incidental consequences. There is a limitation of conclusiveness because of overshadow of bone structures and the narrow joint space. The cruciate ligaments and the imaging of the menisci, whose evaluation is still in discussion, are especially concerned. The method is excellent useful for clarification of traumatic or other soft tissue alterations in popliteal as well as in medial and lateral but also in supra--and infrapatellar region. With improvement of the equipment, e.g. the transmissionsonography, this diagnostic method for knee-joint could get greater importance.
