This chapter discusses wear phenomena of ultra-high molecular weight polyethylene (UHMWPE) in artificial joints. The importance of wear in artificial joints, lubrication modes in artificial joints as UHMWPE-on-hard and improving methods for wear reduction of UHMWPE are reviewed. Wear phenomena of UHMWPE artificial knee joints are discussed with reference to the wear characteristics of retrieved artificial knee joints, together with an experimental study on the delamination mechanism of UHMWPE, macroscopic contact analysis between the femoral component and tibial insert, and microscopic contact analysis between surface asperities and tibial inserts.
