There are currently no reports on the clinical outcomes after total hip arthroplasty (THA) with previous curved periacetabular osteotomy (CPO), although the outcomes after THA with non-CPO types of periacetabular osteotomy have been reported. This study aimed to clarify the differences in clinical outcomes and radiographic features after THA with or without previous CPO. We performed a retrospective case-control with individual matching study. The participants were 10 patients with 11 hips that underwent cementless THA between October 1998 and October 2018 with previous CPO (osteotomy group). For the control group, we matched age, sex, and follow-up period, and included 32 patients with 33 hips that underwent cementless THA without previous CPO at a 1:3 ratio. The Harris Hip Score (HHS), cup size, position, and alignment, global offset (GO), operative time, perioperative blood loss, frequency of osteophyte removal, and major complications were compared between the two groups. The osteotomy group had no cases with revision surgery and dislocation. No significant differences were found between the two groups as follows: mean HHS, 94.9 points in the osteotomy group versus 92.7 points in the control group at the final follow-up; mean GO, 70.1 mm in the osteotomy group versus 71.4 mm in the control group; cup size, position, and alignment after THA; operative time; and perioperative blood loss. The frequency of osteophyte removal was higher in the osteotomy group. The take-home messages were that the clinical outcomes, including HHS, and radiographic features, including GO, after THA were equivalent in the two groups.
目前尚无关于既往行髋臼周围弧形截骨术（CPO）后全髋关节置换术（THA）临床结局的报道，尽管已有关于非CPO类型髋臼周围截骨术后THA结局的报道。本研究旨在阐明既往行或未行CPO的THA术后临床结局和影像学特征的差异。我们进行了一项个体匹配的回顾性病例对照研究。参与者为1998年10月至2018年10月期间接受非骨水泥型THA且既往行CPO的10例患者（共11髋）（截骨组）。对于对照组，我们匹配了年龄、性别和随访时间，按1:3的比例纳入了32例患者（共33髋），这些患者接受了非骨水泥型THA且既往未行CPO。比较了两组的Harris髋关节评分（HHS）、髋臼杯大小、位置和对线、整体偏移（GO）、手术时间、围手术期失血、骨赘清除频率和主要并发症。截骨组无翻修手术和脱位病例。两组在以下方面未发现显著差异：末次随访时的平均HHS，截骨组为94.9分，对照组为92.7分；平均GO，截骨组为70.1mm，对照组为71.4mm；THA术后髋臼杯大小、位置和对线；手术时间；以及围手术期失血。截骨组的骨赘清除频率更高。关键信息是，两组THA术后的临床结局（包括HHS）和影像学特征（包括GO）相当。
