The medical examination ("medical") is an important procedure in professional soccer since it has high economic relevance. In addition to clinical tests, magnetic resonance imaging (MRI) is used to assess joint health. In the present study, the reliability of semiquantitative knee MRI during the "medical" in professional soccer was tested, and its relationship with clinical data and days missed due to knee injury was observed.
In this cross-sectional study, between 2012 and 2019, 69 newly assigned players (age 18-35 years) from a professional soccer club underwent MRI (3.0 T) of both knee joints during their "medical". Reported knee injuries and previously missed days due to injury were obtained from player anamnesis and the "transfermarkt.com" database. Based on the established "Whole-Organ Magnetic Resonance Imaging Score" (WORMS), two independent radiologists graded the MRI results. Further evaluation was based on the mean score of both knees.
The mean WORMS for all subjects was 13.9 (median 10.5, range 0-61). Players with previous injuries had significantly higher scores than players without reported injuries (22.1 ± 17.7 vs. 8.9 ± 4.4, p < 0.002). Three outliers (previously undetected injuries) in the group of players without reported injuries were observed (6.7%). The WORMS was significantly correlated with a prior knee injury (r: 0.424, p < 0.0001) and days missed due to injury (r: 0.489, p < 0.001). Age was correlated with the WORMS (r: 0.386, p < 0.001). In a linear regression model, prior injury was the only significant predictor of a high WORMS (p = 0.001). The WORMS was a significant predictor of days missed due to injury (p < 0.0002) and prior injury (sensitivity: 78%, specificity: 91%, p = 0.006). The intraclass correlation coefficient was excellent (0.89).
Semiquantitative knee MRI for WORMS determination during the soccer "medical" is a robust and reliable method. Prior injury, even in players without documented trauma, was detected by the WORMS, and previously missed days due to injury were correlated with the semiquantitative MR knee score.

医学检查（“体检”）在职业足球中是一个重要的程序，因为它具有很高的经济意义。除了临床检查外，磁共振成像（MRI）也被用于评估关节健康。在本研究中，我们测试了职业足球体检中膝关节 MRI 半定量检查的可靠性，并观察了其与临床数据和因膝关节损伤而错过的天数之间的关系。
本研究为一项横断面研究，2012 年至 2019 年间，一家职业足球俱乐部的 69 名新分配球员（18-35 岁）在接受体检时接受了双侧膝关节 3.0T MRI 检查。从球员病史和“transfermarkt.com”数据库中获得了膝关节损伤的报告和之前因伤错过的天数。根据既定的“整体磁共振成像评分”（WORMS），两名独立的放射科医生对 MRI 结果进行了分级。进一步的评估基于两个膝关节的平均评分。
所有受试者的平均 WORMS 评分为 13.9（中位数 10.5，范围 0-61）。有既往损伤的球员的评分明显高于无报告损伤的球员（22.1±17.7 比 8.9±4.4，p<0.002）。在无报告损伤的球员组中，观察到 3 个离群值（以前未检出的损伤）（6.7%）。WORMS 与既往膝关节损伤显著相关（r：0.424，p<0.0001）和因伤错过的天数（r：0.489，p<0.001）。年龄与 WORMS 相关（r：0.386，p<0.001）。在线性回归模型中，既往损伤是 WORMS 升高的唯一显著预测因素（p=0.001）。WORMS 是因伤错过的天数（p<0.0002）和既往损伤（敏感性：78%，特异性：91%，p=0.006）的显著预测因素。组内相关系数为 0.89，非常好。
在职业足球体检中，膝关节 MRI 半定量 WORMS 测定是一种可靠的方法。即使在没有记录创伤的球员中，WORMS 也能检测到既往损伤，并且因伤错过的天数与膝关节半定量 MRI 评分相关。
