The effect of obesity on outcome for patients undergoing hip resurfacing has been evaluated. Pre and post-operative objective patient scored outcomes for a group of 181 cases of hip resurfacing performed over a three year period were collected. Cases have been stratified by body mass index (BMI) with evaluation of post-operative complications. Patient outcomes included: SF-36, WOMAC, and satisfaction scores, and were compared pre-operatively, and at one year. We found an increased rate of wound complications in the obese group (BMI > 30) with 4 cases of prolonged wound drainage and 2 superficial infections, compared to none in the non-obese group. A similar improvement in SF-36, WOMAC and patient satisfaction was found for both groups. No increase in the risk of femoral neck fracture or aseptic loosening was seen in the obese group. These results suggest excellent early outcomes for obese patients undergoing hip resurfacing with no added risk of early failure.
肥胖对接受髋关节表面置换术患者预后的影响已得到评估。收集了一组在三年期间进行的181例髋关节表面置换术患者术前和术后的客观评分结果。根据体重指数（BMI）对病例进行分层，并评估术后并发症。患者预后指标包括：SF-36健康调查简表、西安大略和麦克马斯特大学骨关节炎指数（WOMAC）以及满意度评分，并在术前和术后一年进行比较。我们发现肥胖组（BMI>30）伤口并发症发生率增加，有4例伤口引流延长和2例浅表感染，而非肥胖组无此类情况。两组在SF-36、WOMAC和患者满意度方面都有类似的改善。肥胖组未发现股骨颈骨折或无菌性松动风险增加。这些结果表明，肥胖患者接受髋关节表面置换术的早期预后良好，且无早期失败风险增加。
