The core of the present problem was to indicate the values of the optimum synovial fluid velocity and friction forces appearing near the cartilage cells of cooperating surfaces, as well as to find the ways of controlling the friction forces between particles of the liquid and the cells of the biobearing cooperating bodies in the thin boundary layer. In the research, we used a numerical method. Investigations of the physical and strength features are expected to be performed for various kinds of biobearing superficial layer and for damage to biobearings. In order to begin treating the surface structure of a superficial layer on the cooperating biobearing surfaces it is absolutely necessary to build a proper model of a liquid flow in the thin layer and to obtain the proper values of friction forces.
