Objectives Critically appraise and summarise the measurement properties of knee muscle strength tests after anterior cruciate ligament (ACL) and/or meniscus injury using the COnsensus-based Standards for the selection of health Measurement INstruments Risk of Bias checklist. Design Systematic review with meta-analyses. The modified Grading of Recommendations Assessment, Development and Evaluation-guided assessment of evidence quality. Data sources Medline, Embase, CINAHL and SPORTSDiscus searched from inception to 5 May 2022. Eligibility criteria for selecting studies Studies evaluating knee extensor or flexor strength test reliability, measurement error, validity, responsiveness or interpretability in individuals with ACL and/or meniscus injuries with a mean injury age of ≤30 years. Results Thirty-six studies were included involving 31 different muscle strength tests (mode and equipment) in individuals following an ACL injury and/or an isolated meniscus injury. Strength tests were assessed for reliability (n=8), measurement error (n=7), construct validity (n=27) and criterion validity (n=7). Isokinetic concentric extensor and flexor strength tests were the best rated with sufficient intrarater reliability (very low evidence quality) and construct validity (moderate evidence quality). Isotonic extensor and flexor strength tests showed sufficient criterion validity, while isometric extensor strength tests had insufficient construct and criterion validity (high evidence quality). Conclusion Knee extensor and flexor strength tests of individuals with ACL and/or meniscus injury lack evidence supporting their measurement properties. There is an urgent need for high-quality studies on these measurement properties. Until then, isokinetic concentric strength tests are most recommended, with isotonic strength tests a good alternative.

前交叉韧带和/或半月板损伤后肌肉力量测试的测量特性：使用什么测试以及我们需要去哪里？对 OPTIKNEE 共识进行荟萃分析的系统评价

目标 使用基于共识的健康测量仪器选择风险检查表标准，批判性地评估和总结前交叉韧带 (ACL) 和/或半月板损伤后膝关节肌肉力量测试的测量特性。设计系统评价与荟萃分析。修改后的建议分级评估、制定和评估指导的证据质量评估。数据来源 Medline、Embase、CINAHL 和 SPORTSDiscus 从开始到 2022 年 5 月 5 日进行了搜索。 选择研究的资格标准 评估膝关节伸肌或屈肌力量测试可靠性、测量误差、有效性、反应性或可解释性的研究平均受伤年龄≤30岁。结果 36 项研究被纳入，涉及 31 种不同的肌肉力量测试（模式和设备），在 ACL 损伤和/或孤立的半月板损伤后的个体中进行。对强度测试的可靠性 (n=8)、测量误差 (n=7)、结构有效性 (n=27) 和标准有效性 (n=7) 进行了评估。等速同心伸肌和屈肌力量测试的评分最高，具有足够的评估者内部可靠性（极低证据质量）和结构有效性（中等证据质量）。等张伸肌和屈肌力量测试显示出足够的标准有效性，而等长伸肌力量测试的结构和标准有效性不足（证据质量高）。结论 ACL 和/或半月板损伤患者的膝伸肌和屈肌力量测试缺乏支持其测量特性的证据。迫切需要对这些测量特性进行高质量的研究。在那之前，最推荐等速同心力量测试，等张力量测试是一个很好的选择。
