The aim of this study is to evaluate clinical outcomes of patients undergoing Birmingham hip resurfacing (BHR) with a minimum 5-year follow-up and compare these outcomes to 2 matched control groups of patients undergoing either direct anterior approach (DAA) or posterior approach (PA) total hip arthroplasty (THA).
Data between September 2008 and April 2015 were retrospectively reviewed. Male patients were included if they underwent a THA or BHR with minimum 5-year patient-reported outcomes. BHR patients were propensity-score matched in a 1:1 ratio to 2 control groups of patients: one group who underwent DAA THA and one group who underwent PA THA.
Fifty BHR patients were propensity-score matched to 2 control groups: 50 cases of PA THA and 50 cases of DAA THA. Both control groups were well matched with respect to demographics. The BHR 5-year patient-reported outcomes were comparable to both control groups. The BHR cohort compared favorably to the PA THA group with no significant differences in their average Forgotten Joint Score (77.9, 79.4, P = .84 respectively) and the number of patients reporting a score greater than or equal to 50 were also comparable, 41 (82%), 42 (84%), P = .79 respectively.
BHR yielded good functional status and outcomes, which compared favorably with control groups of DAA THA and PA THA. Decision-making should be based upon other factors such as potential risk factors, the surgeon's and patient's preferences, and the patient's physical demand.
本研究旨在评估接受 Birmingham 髋关节表面置换术（BHR）治疗的患者在至少 5 年随访后的临床结果，并与接受直接前路（DAA）或后路（PA）全髋关节置换术（THA）的 2 组匹配对照组进行比较。
回顾性分析 2008 年 9 月至 2015 年 4 月的数据。如果男性患者接受了至少 5 年的患者报告结果的 THA 或 BHR，则将其纳入研究。BHR 患者按 1:1 的比例与 2 组匹配的对照组患者进行倾向评分匹配：一组患者接受 DAA THA，另一组患者接受 PA THA。
50 例 BHR 患者与 2 个对照组（PA THA 50 例和 DAA THA 50 例）进行了倾向评分匹配。两组对照组在人口统计学方面均匹配良好。BHR 5 年患者报告结果与两组对照组相当。BHR 组与 PA THA 组相比具有优势，其平均遗忘关节评分（77.9、79.4，P=0.84 分别）无显著差异，报告评分大于或等于 50 的患者比例也相似，分别为 41 例（82%）和 42 例（84%），P=0.79。
BHR 可获得良好的功能状态和结果，与 DAA THA 和 PA THA 对照组相比具有优势。决策应基于其他因素，如潜在的危险因素、外科医生和患者的偏好以及患者的身体需求。
