To translate, culturally adapt, evaluate the measurement properties, and propose a new scoring system of the Cincinnati Knee Rating System for the Brazilian population. One hundred fifty people with anterior cruciate ligament injury completed Cincinnati Knee Rating System and Lysholm Knee Scoring Scale on three occasions: 1-week prior to surgery, 90-days after and 95-days after reconstruction. The measurement properties of the Brazilian-Portuguese Cincinnati Knee Rating System, internal consistency, construct validity, reproducibility, ceiling and floor effect and responsiveness, were tested. Using the original scoring system (multiple scores), the internal consistency (Cronbach's α) varied between 0.54-0.79 (if item deleted = 0.07-0.73); the construct validity (Pearson's ) varied between 0.19-0.82 (related to Lysholm); the reliability (intraclass correlation coefficient) varied between 0.96-0.99; the standard error of measurement varied between 0.2-1.3 points; the minimum detectable change varied between 0.4-3.5 points; no ceiling or floor effect was detected, and responsiveness (effect size) varied between -0.3-2.7. Using the new proposed scoring system (single score), Cronbach's α was 0.78 (if item deleted = 0.65-0.71); the Pearson's was 0.79 (related to Lysholm); the intraclass correlation coefficient was 0.99; the standard error of measurement was 0.5 points, the minimum detectable change was 1.3 points; no ceiling or floor effect was detected, and effect size was 1.4. The Brazilian-Portuguese Cincinnati Knee Rating System has adequate property measurement and can be used in a Brazilian population. The new proposed scoring system is appropriate.Implications for rehabilitationThe Brazilian-Portuguese Cincinnati Knee Rating System is a valid and reliable instrument which can identify consistent clinical changes over the time.The Brazilian-Portuguese Cincinnati Knee Rating System can be used to evaluate and to follow-up a Brazilian population with anterior cruciate ligament injuries and postoperative reconstruction.The new proposed score for Cincinnati Knee Rating System is appropriate and did not compromise the quality of the measurement properties.The new scoring system generates a unique score, creating a potentially simpler and faster clinical understanding of the patient's condition.
为了将 Cincinnati 膝关节评分系统翻译、文化适应、评估其测量属性，并为巴西人群提出新的评分系统。150 名前交叉韧带损伤患者在三次就诊时完成了 Cincinnati 膝关节评分系统和 Lysholm 膝关节评分量表：手术前 1 周、术后 90 天和 95 天。对巴西葡萄牙语 Cincinnati 膝关节评分系统的测量属性，包括内部一致性、结构有效性、可重复性、天花板和地板效应以及反应性进行了测试。使用原始评分系统（多项评分），内部一致性（Cronbach's α）在 0.54-0.79 之间（如果项目删除则为 0.07-0.73）；结构有效性（Pearson's ）在 0.19-0.82 之间（与 Lysholm 相关）；可靠性（组内相关系数）在 0.96-0.99 之间；测量标准误差在 0.2-1.3 分之间；最小可检测变化在 0.4-3.5 分之间；未检测到天花板或地板效应，反应性（效应量）在-0.3-2.7 之间变化。使用新提出的评分系统（单项评分），Cronbach's α 为 0.78（如果项目删除则为 0.65-0.71）；Pearson's 为 0.79（与 Lysholm 相关）；组内相关系数为 0.99；测量标准误差为 0.5 分，最小可检测变化为 1.3 分；未检测到天花板或地板效应，效应量为 1.4。巴西葡萄牙语 Cincinnati 膝关节评分系统具有良好的属性测量能力，可用于巴西人群。新提出的评分系统是合适的。康复意义巴西葡萄牙语 Cincinnati 膝关节评分系统是一种有效且可靠的工具，可在一段时间内识别一致的临床变化。巴西葡萄牙语 Cincinnati 膝关节评分系统可用于评估和随访前交叉韧带损伤和术后重建的巴西人群。新提出的 Cincinnati 膝关节评分系统评分是合适的，并没有降低测量属性的质量。新的评分系统生成了一个独特的分数，为患者的病情提供了更简单、更快速的临床理解。
