1420 primary cementless THRs with a minimum follow-up of 10-years were stratified according to BMI: non-obese (BMI<30kg/m(2)) and obese (BMI≥30kg/m(2)). Median age at surgery was younger in obese patients (P<0.001). We case-matched 82 THRs in obese patients with 162 THRs in non-obese patients. No difference between groups was found in improvement in HHS (P=0.668), satisfaction with surgery (P=0.644), range of movement, prosthesis orientation, or radiological loosening. The obese cohort was further separated into those with a BMI below and above 35. No difference was found between groups in improvement in HHS, satisfaction with surgery, component orientation, or radiological loosening. There was no difference in the incidence of post-operative complications between obese and non-obese patients. After 10-years, the results of THR are not compromised by obesity.
1420例初次非骨水泥型全髋关节置换术患者，随访至少10年，根据体重指数（BMI）分层：非肥胖（BMI<30kg/m²）和肥胖（BMI≥30kg/m²）。肥胖患者手术时的中位年龄较轻（P<0.001）。我们将82例肥胖患者的全髋关节置换术与162例非肥胖患者的全髋关节置换术进行病例匹配。两组在髋关节 Harris 评分（HHS）改善情况（P=0.668）、手术满意度（P=0.644）、活动范围、假体位置或影像学松动方面均未发现差异。肥胖队列进一步分为BMI低于和高于35的两组。两组在HHS改善情况、手术满意度、假体组件位置或影像学松动方面均未发现差异。肥胖患者和非肥胖患者术后并发症的发生率没有差异。10年后，肥胖并不影响全髋关节置换术的结果。
