Highly cross‐linked polyethylene is the new ‘gold standard’ bearing material for total hip arthroplasty

Biosurface and Biotribology, 2021
Conventional polyethylene is not used much in total hip arthroplasty (THA); it has been supplanted by oxidation‐resistant cross‐linked polyethylene (≥50 kGy irradiation). However, studies persist that de‐emphasize or ignore cross‐linked polyethylene.
