Introduction	Prior research established the 5-year performance of the Birmingham Hip Resurfacing (BHR) implant. The current investigation extends this assessment, focusing on BHR survivorship, radiographic findings, and clinical outcomes over an extended follow-up period. This analysis involved 224 patients meeting current indications, with 179 participants from the initial cohort. Survivorship was determined, and metal ion levels along with radiographic data were updated. Patient-reported outcomes (PROs) were benchmarked against a matched group who underwent total hip arthroplasty (THA). The average follow-up spanned 14 years. At 15 years, survivorship without any revision was 96.0%, and aseptic revision-free survivorship reached 97.4%. Only two patients required revision since the initial publication. Median serum cobalt and chromium concentrations were recorded at 1.4 and 1.5 ppb, respectively. Patient-reported outcomes aligned with those observed in the THA group. While comparable proportions of patients maintained activity, the BHR cohort exhibited a tendency for a higher percentage to remain highly active (p = 0.12). Despite similar activity levels to THA in the long term, the BHR implant continues to be a highly suitable choice for managing osteoarthritis in younger male patients.
