目的：本研究的目的是翻译和文化适应膝关节损伤和骨关节炎的结果评分（KOOS）的葡萄牙语，并测试其可靠性，有效性，地板/天花板的影响和responsibility.Methods：这个新版本获得了向前/向后的翻译，共识面板和预测试。葡萄牙KOOS和医疗结果研究-36项简表（SF-36）问卷、疼痛、残疾和不适的视觉模拟量表（VAS）以及患者特征表应用于223例膝关节骨关节炎（OA）受试者。Cronbach α系数在0.77 ~ 0.95之间，KOOS分量表的组内相关系数（ICC）范围为0.82至0.94。通过确认7个预先定义的假设中的6个（涉及KOOS分量表、SF-36分量表和VAS之间的预期相关性）来支持结构效度。一个额外的预先定义的假设也得到了证实，需要助行器的受试者在所有五个KOOS分量表中得分较低（P
Objective: The objective of this study was to translate and culturally adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) to the Portuguese language and to test its reliability, validity, floor/ceiling effects and responsiveness.Methods: This new version was obtained with forward/backward translations, consensus panels and a pre-test. The Portuguese KOOS and Medical Outcomes Study - 36 item Short Form (SF-36) questionnaires, visual analogue scales (VAS) of pain, disability and discomfort, and a form for the characteristics of the patients were applied to 223 subjects with knee osteoarthritis (OA).Results: Reliability was acceptable with Cronbach's alpha coefficients between 0.77 and 0.95, and intraclass correlation coefficients (ICC) ranging from 0.82 to 0.94 for the KOOS subscales. Construct validity was supported by the confirmation of six of the seven predefined hypotheses involving expected correlations between KOOS subscales, SF-36 subscales and VAS. An additional predefined hypothesis was also confirmed with the subjects that need walking aids obtaining lower scores in all five KOOS subscales (P
