Our hypothesis was that return of function for young patients undergoing resurfacing total hip arthroplasty (THA) with metal-on-metal bearings or contemporary THA with ceramic bearings would be comparable. Results from 337 unilateral hip resurfacing patients were compared with results from 266 unilateral ceramic-on-ceramic THA patients. Early differences in Harris Hip Scores were observed, but all differences faded by 24 months. Hip resurfacing seems to be a viable alternative to THA for well-selected patients. However, the public perception of improved functional capabilities was not demonstrated in this patient population. Resurfacing patients may be more impaired (slightly higher pain scores/lower function scores) than their THA counterparts in the early postoperative period, but these differences disappear by 24 months when both groups report Harris Hip Scores in the excellent range.
我们的假设是，接受金属对金属或当代陶瓷对陶瓷轴承表面置换全髋关节置换术 (THA) 的年轻患者的功能恢复将具有可比性。将 337 例单侧髋关节表面置换患者的结果与 266 例单侧陶瓷对陶瓷 THA 患者的结果进行了比较。观察到 Harris 髋关节评分的早期差异，但所有差异在 24 个月时均消失。对于精选的患者来说，髋关节表面置换似乎是 THA 的可行替代方法。然而，在这群患者中，并未显示出公众对改善功能能力的认知。在术后早期，表面置换患者可能比他们的 THA 患者更受影响（疼痛评分略高/功能评分略低），但当两组均报告 Harris 髋关节评分为优秀范围时，这些差异在 24 个月时消失。
