我们为接受全膝关节置换术(TKR)的患者开发了一份包含12个项目的问卷。我们在手术前和6个月后的随访中对117名患者进行了前瞻性研究，要求他们完成新的问卷和SF36表格。一些人还填写了斯坦福健康评估问卷(HAQ)。一名骨科医生完成了美国膝关节协会(AKS)的临床评分。新问卷得出的单项评分具有很高的内部一致性，通过重测可靠性检验，其重复性被发现是令人满意的。其效度是通过获得预期方向与AKS评分以及SF36和HAQ的相关部分的显著相关来建立的。通过分析术前和术后评分的差异来评估对变化的敏感性。我们还将评分的变化与患者对病情变化的回顾判断进行了比较。新问卷的效度与SF36相关部分的效度相比具有较好的效度。对于报告病情改善最多的患者，新的膝关节问卷的变化分数明显更高(p<；0.0001)。新的问卷为全膝关节置换提供了一种短期、实用、可靠、有效和对随着时间推移的临床重要变化敏感的结果的衡量标准。
We have developed a 12-item questionnaire for patients having a total knee replacement (TKR). We made a prospective study of 117 patients before operation and at follow-up six months later, asking them to complete the new questionnaire and the form SF36. Some also filled in the Stanford Health Assessment Questionnaire (HAQ). An orthopaedic surgeon completed the American Knee Society (AKS) clinical score.The single score derived from the new questionnaire had high internal consistency, and its reproducibility, examined by test-retest reliability, was found to be satisfactory. Its validity was established by obtaining significant correlations in the expected direction with the AKS scores and the relevant parts of the SF36 and HAQ. Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at follow-up.We also compared change in scores with the patients' retrospective judgement of change in their condition. The effect size for the new questionnaire compared favourably with those for the relevant parts of the SF36. The change scores for the new knee questionnaire were significantly greater (p < 0.0001) for patients who reported the most improvement in their condition.The new questionnaire provides a measure of outcome for TKR that is short, practical, reliable, valid and sensitive to clinically important changes over time.
