Joint replacement bearing material behavior

Material behavior of medical grade ultra-high molecular weight polyethylene (UHMWPE) was identified as a serious concern as it limits the overall lifetime and success of a joint replacement. Although total joint arthroplasty involving UHMWPE as a bearing surface has been one of the most successful procedures of the last century, issues of wear, oxidation, and fatigue failure remain obstacles to the longevity of joint replacements.
