[Case report of a patient with knee gout].

A 46-years old male presented with an attack of gout (knee arthritis or gonagra). It is interesting that the patient was HLA B27 positive antigen found a couple of years ago, but on admission he had a normal findings of uric acid in serum, while cytological examination of synovial fluid obtained from knee joint no urates were found. Therefore, diagnostically besides gout arthritis a reactive arthritis as well as other connective tissue diseases were considered. In further diagnostic procedure arthroscopy was performed and in biopsy specimen from the cyst of lateral condyle of right femur urates were found. One day after the arthroscopy was performed a clear clinical picture of podagra developed. After the diagnosis was made the treatment of gout arthritis with Indometacyn began, and with improvement of inflammation, surgery was performed--cyst excochelation of lateral condyle of right femur with filling of the defect with an autologous graft from iliac crest.
