The micropolar fluid theory was applied to answer the question how the microstructure dependence of synovial fluid influences on tribological quantities of biobearing. The squeezing flow of micropolar fluid between two parallel circular plates was considered, as an approximation for the lubrication in the weight bearing synovial joint under conditions where the area of contact is maximum such as in standing and jumping. The generalised Reynolds equation to describe the flow fields was applied. The calculations show that the load bearing capacity and time of approach depend strongly on micrustucture of synovial fluid. Obtained results are in agreement with clinical observations, which indicates that proposed approach based on micropolar fluid mechanics can be applied to modeling of synovial fluid.
