Introduction The long-term survival of total hip arthroplasties (THAs) is around 80% to 90% after 20 years depending on diagnosis and age.1-4 Implant failure is primarily caused by aseptic loosening, which is associated with wear debris from polyethylene liners.1,5,6 A significant reduction in wear and risk of osteolysis can be achieved by using cross-linked polyethylene (XLPE) liners instead of ultra high molecular weight polyethylene (UHMWPE) liners for metal-on-polyethylene THAs.7-9 To...
