Excerpt
Highly crosslinked polyethylene (XLPE) has essentially supplanted conventional polyethylene for use in total hip arthroplasty (THA) during the past decade. There now exists good evidence to demonstrate a clear reduction in femoral head penetration (and presumably polyethylene wear) and periprosthetic osteolysis associated with the use XLPE compared to conventional polyethylene in THA [
2,
3]. While the annual reports of Australian Orthopaedic Association National Joint Replacement Registry continue to show the clinical benefits of XLPE (demonstrating a reduction in revision rates) [
1], other investigators have not demonstrated a clear reduction in revision rates with the use of XLPE at mid-term followup [
4]. …
