[Anatomical basis of ultrasonography of the knee].

Authors show the structures of the knee joint that can be demonstrated by ultrasound. It is stated that in normal circumstances the tendons, the collateral ligaments, the bursae and Hoffa's fat tissue can be easily brought in the visual field. The demonstration of the single parts of the menisci and the cruciate ligaments is more difficult in certain cases (bulky knee, contracture, progressed gonarthrosis). Corresponding to the literary data and on the basis of their results they conclude that the ultrasound is suitable to the correct demonstration of the complicated anatomy of the knee. The examination is noninvasive, it can be repeated any time and with adequate experience it gives possibility to recognise the changes in the knee joint.
