To determine whether visually assessed performances of the single-leg squat (SLS) and vertical drop jump (VDJ) were associated with future noncontact anterior cruciate ligament (ACL) injury.
Prognostic accuracy cohort study.
Elite female handball and football (soccer) athletes (n = 880) were tested from 2007 to 2014 and tracked through 2015. Trained physical therapists visually rated each leg during a SLS and overall control during a VDJ. Receiver operating characteristic curve, Pearson chi-square, and logistic regression analyses were used to determine the prognostic accuracy of the 2 screening tests.
Sixty-five noncontact ACL injuries occurred during the follow-up period. Fourteen percent of athletes who sustained an ACL injury had poor SLS performance, compared to 17% of the noninjured athletes ( = .52 and .67 for hip and knee ratings, respectively). Side-to-side asymmetry in the SLS was not different between injured and noninjured athletes ( = .10 and .99 for hip and knee asymmetry, respectively). Twenty-one percent of athletes who sustained an ACL injury had a poor VDJ rating, compared to 27% of the noninjured athletes ( = .09). Furthermore, area under the curve values ranged from 0.43 to 0.54 for the SLS and VDJ, demonstrating no to poor prognostic accuracy.
Neither SLS nor VDJ test performance distinguished between athletes who sustained a subsequent noncontact ACL injury and those who did not. .
确定单腿深蹲（SLS）和垂直跳落（VDJ）的视觉评估表现是否与未来的非接触性前交叉韧带（ACL）损伤有关。
预后准确性队列研究。
对 2007 年至 2014 年期间的精英女子手球和足球（足球）运动员（n=880）进行了测试，并通过 2015 年进行了跟踪。经过培训的物理治疗师在 SLS 期间对每条腿进行视觉评估，并在 VDJ 期间对整体控制进行评估。使用接收者操作特征曲线、Pearson χ2 检验和逻辑回归分析来确定这两种筛选测试的预后准确性。
在随访期间发生了 65 例非接触性 ACL 损伤。14%的 ACL 损伤运动员的 SLS 表现较差，而非受伤运动员的比例为 17%（分别为髋关节和膝关节评分为.52 和.67）。受伤和未受伤运动员的 SLS 侧间不对称性无差异（分别为髋关节和膝关节不对称性为.10 和.99）。21%的 ACL 损伤运动员的 VDJ 评分较差，而非受伤运动员的比例为 27%（=0.09）。此外，SLS 和 VDJ 的曲线下面积值范围为 0.43 至 0.54，表明预后准确性不佳。
SLS 和 VDJ 测试表现均无法区分随后发生非接触性 ACL 损伤的运动员和未发生损伤的运动员。
