Wear and migration are not influenced by head size in a vitamin E-infused highly cross-linked polyethylene acetabular cup.

Background: Aseptic loosening and periprosthetic osteolysis are frequent complications in total hip arthroplasty requiring revision surgery. Highly cross-linked polyethylene (HXLPE) implants have improved wear resistance, permitting larger femoral heads. However, such implants may experience surface cracking, mechanical failure, and oxidative damage.
