[The study of indices of electrolytic composition and phosphatase activity of synovial fluid in patients with osteoarthritis of knee joint].

The study was carried out concerning indices of electrolytic content and phosphatase activity of synovial fluid in patients with degenerate dystrophic affections of knee joints stage II and III. The detection of rate of occurrence of alterations of studied indices established that most often occurred increasing of ratio calcium-phosphorus and decreasing of concentration of phosphate-ions. Therefore, concentration of the mentioned indices can be applied in evaluation of conditions of joint medium.
