In the past 2 decades, outcome assessment following knee surgery has focused increasingly on the patient's perspective. While traditional measures of outcome, including physical examination, imaging studies, and measures of knee laxity are complementary, questionnaires have become more important in determining the value of a procedure. Reliability, validity, and responsiveness are all important measurement qualities for health-related quality of life instruments. There are several questionnaires available, both for active patients with disorders of the knee, as well as for older patients with degenerative conditions. Activity level is also an important prognostic variable for patients with disorders of the knee. Clinical researchers should also use a validated activity rating scale to evaluate what patients are doing, in addition to how they are doing.
在过去20年里，膝关节手术后的疗效评估越来越关注患者的观点。虽然传统的疗效指标，包括体格检查、影像学检查和膝关节松弛度测量是相辅相成的，但问卷在确定手术价值方面变得更加重要。可靠性、有效性和反应性都是与健康相关的生活质量工具的重要测量特性。有几种问卷可供使用，既适用于患有膝关节疾病的活跃患者，也适用于患有退行性疾病的老年患者。活动水平也是膝关节疾病患者的一个重要预后变量。临床研究人员除了评估患者的状态外，还应使用经过验证的活动评分量表来评估患者的活动情况。
