[Comparison of sonography and arthrography in the examination of cysts around the knee].

Authors used in 1988 simultaneously sonography and arthrography during the treatment of 10 patients admitted with the diagnosis of cyst or tumour around the knee. The experiences with the comparison of the 2 methods are summarized. As this use of the method is first described in this country, before the description of their own material the relevant available foreign literature is also discussed. It is stated that in the differential diagnosis of the cysts around the knee the 2 methods may give good complementary informations. It is stressed that if a choice is possible, the sonography is the method of choice, being exempt from X-rays, noninvasive, not causing pain and cheaper.
