Total hip arthroplasty performed with first-generation annealed highly cross-linked polyethylene bearings in young, active patients showed 97% survivorship at 10 years and a low revision rate for wear-related failure.

Researchers identified 91 patients who underwent 112 total hip arthroplasty (THA) procedures between 1999 and 2003 with an average University of California Los Angeles Activity Score of 8 and a mean age of 53 years. All patients received a 28-mm metal femoral head on annealed highly cross-linked polyethylene (Stryker) bearing, according to researchers.

Results showed patients had an average WOMAC score of 94, a patient-administered questionnaire score of 65 and a Hospital for Special Surgery hip score of 37. Researchers found 98% of patients were satisfied with their surgery. According to results, Kaplan-Meier survivorship was 97% for all failures and 100% for mechanical failure at a minimum 10-year follow-up. – by Casey Tingle
