A Model for the Lubrication Mechanism in Knee Joint Replacement

Analytical studies are presented for the understanding of the lubrication mechanism occuring in knee joint replacement under restricted motion. The idealised model has been shown to produce results consistent with those in normal situations. Effects of increase in viscoelastic parameter of the lubricant are similar to those of increase in the concentration of hyaluronic acid molecules in synovial fluid. Slip velocity occuring at the poroelastic boundary helps in normal functioning of the joints
