Thirteen methods of hip scoring were applied in the postoperative assessment of 47 hip arthroplasties. Their results were found to be inconsistent, often giving contrary measures of success in the same patient. Ten variables were measured during the postoperative review of 256 hip arthroplasties and the data were submitted to multivariate factor analysis. This revealed that the ten variables could be reduced to three factors: pain, which correlated poorly with any other variable (Spearman correlation, r < 0.02); functional activity (distance walked, use of walking aids, stair climbing, use of public transport, limp, sitting and tying shoelaces); and deformity and range of movement. The range of hip flexion correlated closely with the sum of the arcs of movement and with Gade's index (Spearman correlation, r > 0.9). We suggest that, for outcome assessment, only three variables need to be recorded: pain, walking distance and range of hip flexion. The combination of these three measures into a single hip score is misleading.
13种髋关节评分方法被应用于47例髋关节置换术的术后评估。结果发现这些方法的结果并不一致，常常对同一患者的成功程度给出相反的衡量。在对256例髋关节置换术进行术后复查时测量了10个变量，并将数据进行多元因子分析。结果显示这10个变量可归纳为三个因素：疼痛，与其他任何变量的相关性都很差（斯皮尔曼相关性，r < 0.02）；功能活动（行走距离、助行器使用情况、爬楼梯、公共交通使用情况、跛行、坐姿和系鞋带）；以及畸形和活动范围。髋关节屈曲范围与活动弧度总和及加德指数密切相关（斯皮尔曼相关性，r > 0.9）。我们建议，为进行结果评估，只需记录三个变量：疼痛、行走距离和髋关节屈曲范围。将这三项指标合并为单一的髋关节评分会产生误导。
