Abstract
The hemi-arthroplasty is the arthroplasty by replacing one of articular surfaces in diseased natural joint to artificial component and recovers a function of the joint or releases from the pain for patients. In this study to simulate the hemi-arthroplasty, friction and wear for rubbing pair of PVA (polyvinyl alcohol) hydrogel and natural cartilage were evaluated in reciprocating wear tester by changing the lubricant. The lubricant containing protein reduced wear of the articular cartilage and the lubricant containing hyaluronic acid reduced wear of PVA hydrogel. The difference was observed in changing of protein type.
