Survivorship was calculated. Metal ion levels and radiographs were updated. Patient-reported outcomes (PROs) were compared with those for matched patients who had undergone total hip arthroplasty (THA). The mean follow-up was 14 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Survivorship free from any revision and from aseptic revision was 96.0% and 97.4% at 15 years, respectively. Two patients had undergone revision since the original study. The median serum cobalt and chromium levels were 1.4 and 1.5 ppb, respectively. The PROs were similar to those for the THA cohort. Equal proportions of patients remained active; however, the BHR group trended toward more remaining highly active (p = 0.12).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Although activity was similar to THA at long-term follow-up, the BHR implant remains an excellent option for the treatment of osteoarthritis in younger male patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level III<\/jats:underline>\n                      .
