Minimum Five-Year Outcomes of Hip Resurfacing: Propensity-Score Matched Against Total Hip Arthroplasty Control Groups.

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. Copyright © 2021 Elsevier Inc.
