Effects of Synovial Fluid Constituents on Friction between UHMWPE and CoCrMo

In this study, the reciprocating pin-on-plate sliding test was conducted between ultra-high molecular weight polyethylene (UHMWPE) and CoCrMo alloy with test lubricants containing representative synovial fluid constituents, such as proteins, hyaluronic acid, and phospholipids, to understand their ef...
