In this paper, theoretical analysis of effective particles of long-chain polymer on performance
improvement of the human joint is presented. mathematical model depended on a laminar steady flow of
synovial fluid that it contains on hyaluronic acid between articular cartilage in( hip- knee-ankle) joint, where
Reynolds equation governing the fluid film pressure was derived and solved analytically. Quasi-statics
equilibrium equation determined friction force during daily activities, the influence of film thickness and
squeeze action, length of chain and speed on the squeeze film characteristics were discussed. It has been found
that the effect of the decreased film thickness of particle leads to an increase in the load carry capacity, friction
force and decreased flow rate. It is observed that the effect of length of a particle on pressure film between
articular surface with sliding motion is to increase.
