Should HXLPE Be Considered the Gold Standard for THA? (AAOS 2014)
Since its development, ultra-high molecular weight polyethylene (UHMWPE) has been the primary bearing option for total hip arthroplasty (THA). However, highly cross-linked polyethylene (HXLPE), which was introduced in the 1990s, has generally demonstrated superior wear properties to UHMWPE in clinical and laboratory studies.
