Rames RD, et al. - A total of 82 individuals were studied to estimate the polyethylene wear rates, implant survivorship, wear-related revisions, and patient-reported outcomes at 15-year follow-up of total hip arthroplasty (THA). They observed a revision-free survivorship of 97.8% in highly cross-linked polyethylene (HXLPE) group with no wear-related revisions. They recorded volumetric wear rate, 12.80 mm³/yr implying excellent wear properties of HXLPE. They also noticed maintained excellent patient-reported outcomes with improvements in Harris Hip scores (mHHS) and UCLA Activity scores. They concluded the HXLPE and cobalt-chrome bearing couple, extremely useful 15 years after primary THA in subjects of age less than 50 years.
