To gain the understanding of in vivo friction and wear behavior of implanted joint prosthesis, effect of each synovia constituent on the friction between UHMWPE and CoCrMo, the most popular material combination for the sliding surfaces of artificial joints, was examined in the reciprocating sliding tests. Proteins, phospholipids and hyaluronic acid were selected as major constituents of synovial fluid and several test lubricants containing these macromolecules with different combination were prepared to compare the effect on the sliding test results. The result of this study clearly indicated that protein molecules had the predominant effect and it made the effects of other molecules inconspicuous.
