Surface replacement arthroplasty (SRA) has been proposed as a viable option for the treatment of osteoarthritis in young, active patients. Positive results of the Birmingham Hip Resurfacing (BHR) in select patient groups have been described in international series and registry data. We report 5–10 year U.S. follow-up for the BHR at our high volume institution.

314 patients (361 hips) between 2006–2011 underwent BHR at our institution and agreed to participate in research. Demographic features, modified Harris Hip Score, UCLA Activity Score, and satisfaction were recorded for patients with minimum 5-year follow-up (90%). Radiographs were evaluated for implant position and “at risk” signs. Complications, reoperations, and revisions were investigated.

Mean modified Harris Hip and UCLA scores significantly improved postoperatively to scores of 89.96 and 7.90 (p < 0.001), respectively. Kaplan-Meier estimated survival for all-cause revision was 96.7% [95% CI 94.7 – 98.7%] at 5 years and 91.5% [95% CI 85.3 – 97.6%] at 10 years. Estimated survival for aseptic revision in males less than 60 years old with a primary diagnosis of osteoarthritis was 99.5% [95% CI 98.7 – 100%] at 5 years and 98.8% [95% CI 97.0 – 100%] at 10 years. 14 patients required revision, including 5 revisions for adverse local tissue reaction.

Our study demonstrated excellent survivorship and clinical outcomes at 5–10 year follow up for the BHR. These results mirror other series and registry data published outside of the United States. Continued long-term follow-up and additional studies are necessary to validate the long-term safety and outcomes of the BHR, especially in young active arthroplasty patients.
