Precise indications for THA remain unclear and regional differences might exist in selecting patients for surgery. In this study we investigate radiological OA grade and self-reported quality of life in 909 patients undergoing THA in 16 centers across US and Europe. Patients in US were younger and had higher BMI. More patients with mild Tönnis OA grade underwent surgery in the US compared to Europe. Patients in the US had significantly higher pain VAS and significantly lower SF-36 Physical, while having significantly higher EQ-VAS scores preoperatively. Patient demographics and disease severity according to radiological OA grade and self-reported survey scores vary between the United States and Europe. This knowledge can be used in the interpretation of US and European based studies on outcome following THA.
全髋关节置换术（THA）的确切适应症仍不明确，并且在选择手术患者方面可能存在地区差异。在本研究中，我们调查了美国和欧洲16个中心909例接受THA患者的放射学骨关节炎（OA）分级和自我报告的生活质量。美国患者更年轻，体重指数（BMI）更高。与欧洲相比，美国有更多轻度Tönnis OA分级的患者接受了手术。美国患者术前疼痛视觉模拟评分（VAS）显著更高，简明健康状况调查量表（SF-36）身体维度得分显著更低，而欧洲五维健康量表（EQ-VAS）得分显著更高。根据放射学OA分级和自我报告调查得分，美国和欧洲患者的人口统计学特征和疾病严重程度有所不同。这些信息可用于解读基于美国和欧洲的THA术后疗效研究。
