Stainless steel AISI 316L and UHMWPE (Ultra High Molecular Weight Polyethyene) is one of the pair of materials used for the components of the artificial knee joint, where the Stainless Steel 316L replacement femoral component and UHMWPE replacement tibial component, because both materials compatibility with human tissue. Factors that affect the wear are speed, load (pressure), surface roughness and hardness.. The aim of the study is to determine the effect of stainless steel AISI 316L surface roughness and load on the wear properties of UHMWPE. The material used in this study were UHMWPE as a pin and stainless steel AISI 316L as plat. This study used unidirectional reciprocating pin on plate movement to measure the wear factor of UHMWPE. This wear testing was conducted using bovine serum 25 and 75% distilled water as a lubrication. The variation of stainless steel AISI 316L plate surface roughness were 0.02
