Abstract

The aim of the work was to investigate the changes in the values of synovial fluid electrolyte composition in patients with degenerative-and-dystrophic involvements of the joints, as well as to study the dynamics of the mean optical density of femoral and tibial epiphyseal bone structures. The samples of synovial fluid have been studied, as well as the x-rays of 37 patients with deforming arthrosis of the knee of idiopathic and posttraumatic etiology. The decrease of ionized calcium value and the increase of total calcium/inorganic phosphate ratio value have been found. The change in the mean optical density of epiphysis shadow has been demonstrated to be depended on the stage of the pathological process. The relationship of the values of bone structure mean optical density and the concentration of synovial fluid electrolytes evidences the involvement of subchondral zone mineral component in the development of joint pathology. These values can be used as an additional criterion in osteoarthrosis diagnosis, as well as for assessment of subchondral bone condition by biochemical synovial fluid test.
