Abstract

YIGIT, Seyhmus  and  EKINCI, Cenap. Changes in Composition of ADAMTS-5 and CD-68 in the Knee Joint Synovial Fluid Cells of Meniscal Tears Patients an Immunohistochemical Study. Int. J. Morphol. [online]. 2020, vol.38, n.6, pp.1539-1543. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022020000601539.

Meniscus tear is an important injury affecting the quality of life. This work is aimed to investigate the activity of CD68 and ADAMTS-5 in cells in synovial fluid in male and female patients with meniscal tear. In this study ,18 male and 22 female patients with meniscal tears were included. Local pain sensation during patients' physical examination, swelling, performing daily activities and difficulty in running-walking complaints were determined. 5 cc synovial fluids were aspirated from the lateral suprapatellar pouch part of the knees with meniscal pain. After routine histological follow-up of the samples, they were embedded in paraffin and sectioned with microtome and 5 micrometer thickness. CD68 and ADAMTS-5 primary antibodies were used for immunohistochemical analysis. Sections were taken and evaluated with a stylish microscope. The distribution of blood cells after meniscus tear was higher in female patients than in male patients. CD68 distribution in female patients appeared higher than in male patients. CD68 expression was high in macrophage cell cytoplasm. ADAMTS-5 expression was higher in female patients in degenerative cells and apoptotic cells. ADAMTS-5 is an important metallo-protein involved in the development of apoptotic signal and extracellular matrix synthesis in patients with ADAMTS-5 meniscus tear, and it may be an important criterion for the treatment developed after injury. CD68 and ADAMTS-5 activity was thought to be one of the important signal pathways that can be identified in the treatment of meniscus tear.
