Abstract

The effect of synovia constituents, such as a serum protein and hyaluronic acid, on the friction and wear of ultra-high molecular weight polyethylene (UHMWPE) was examined in a pin-on-disk test apparatus. In this study, UHMWPE pin specimens were articulated against stainless steel (SUS316) and alumina ceramic disk specimens. Both saline and diluted bovine serum were used as lubricants. Albumin, a kind of serum protein, and sodium hyaluronate were added to the saline respectively to identify their effects on the friction and wear of UHMWPE. Asa result, each of the synovia constituents had a different influence on the friction and wear of UHMWPE. The wear rate in the albumin solution was not so different from that in the diluted serum, but friction coefficient was higher and the morphology of the wear surfaces observed by scanning electron microscope was quite different. On the other hand, hyaluronic acid could reduce the friction and wear of UHMWPE.
