Bryan AJ, et al. - Researchers investigated 273 participants to evaluate the clinical and radiographic consequences of cases of age less than 50 years experiencing primary total hip arthroplasty (THA) at a minimum of 10 years. They found no revision for wear in the highly cross-linked polyethylene (HXLPE) group vs 6 in the non-HXLPE group (10.5%). They noted significantly higher survivorship with revision for any reason (the endpoint at 16 years) at 93.0% in the XLPE group vs 85.7% in the non-HXLPE group. They included 6 additional revisions in the HXLPE group for instability (2.8%), 5 secondary to infection (2.4%), and 3 stem failures (1.4%). They also included 5 non-wear-related revisions in the non-HXLPE group due to instability (8.8%) and 3 due to stem failures (5.3%). An improvement in the mean Harris Hip Scores for the entire cohort from a mean of 46.2 points preoperatively to 89.8 points at the most recent follow-up.
