Abstract

A laboratory study has been made of the lubrication and friction characteristics of a plastic on metal (Charnley-Muller) and a metal on metal (McKee-Farrar) total hip joint replacement prostheses. The results show the effect of lubricant, speed, and load on the performance of the joints. Under a 560 lb load the coefficient of friction of the plastic to metal joint was lower than that of the metal to metal at speeds up to the equivalent of fast walking. Bovine serum and synovial fluid, as well as human serum albumin were found to be good lubricants of both types of prostheses.
