The results of studying the friction of joint cartilages lubricated by synovia and lubricants without and with additives of liquid crystal compounds are presented. Based on the experimental data, the structural-mechanical and antifriction properties of joint synovia are compared. It is shown that, having in mind the regular structure of surface layers and deformation behavior of cartilages, the present results confirm the assumption on liquid crystal compounds as a cause of low friction in joints. The best tribological characteristics for the combinations with blood serum are demonstrated by drugs based on chondroitin sulfate, which display characteristics close to natural synovial fluid during frictional interaction of cartilage.
