BACKGROUND
The coronavirus 2019 (COVID-19) pandemic resulted in the cancellation of the 2020 National Football League (NFL) preseason and a decreased preseason roster size. The effect of this disruption on athlete injury rates is unknown.
PURPOSE/HYPOTHESIS: The purpose was to quantify the rates of anterior cruciate ligament (ACL), Achilles tendon, and hamstring tendon injuries in NFL players before and after the COVID-19 pandemic. We hypothesized that injury rates in the 2020 season would be higher than those seen prepandemic.
STUDY DESIGN
Descriptive epidemiology study. Level of evidence, 4.
METHODS
An online search using publicly available data was carried out to identify all NFL players who sustained an ACL, Achilles tendon, or hamstring tendon injury between April 1, 2017, and March 31, 2021. Data collected included player characteristics as well as career and season of injury workloads.
RESULTS
The number of Achilles tendon (27 vs 20; = .024) and hamstring tendon (186 vs 149; < .001) injuries, respectively, in the 2020 NFL season were significantly higher than the average of the 2017 to 2019 seasons. However, the number of ACL injuries sustained remained constant (43 vs 46; = .175). More than half (52.9%) of ACL injuries in the 2017 to 2019 seasons occurred in the preseason, while most of the injuries (34.9%) in the 2020 season occurred in weeks 1 to 4. There was no player characteristic or career workload variable collected that was significantly different for players who sustained an ACL, Achilles tendon, or hamstring tendon injury in the 2020 NFL season compared with the 2017 to 2019 seasons.
CONCLUSION
In the 2020 NFL season, the number of Achilles tendon and hamstring tendon injuries rose while the number of ACL injuries remained constant compared with the 2017 to 2019 seasons. Injuries that occurred during the first 4 games of the 2020 NFL season were consistent, with higher rates of injuries seen in the preseason in previous years.
背景
2019年冠状病毒病（COVID - 19）大流行导致2020年美国国家橄榄球联盟（NFL）季前赛取消，季前赛球员名单规模减小。这种赛事中断对运动员受伤率的影响尚不清楚。
目的/假设：目的是量化COVID - 19大流行前后NFL球员前交叉韧带（ACL）、跟腱和腘绳肌腱损伤的发生率。我们假设2020赛季的受伤率会高于大流行前。
研究设计
描述性流行病学研究。证据等级，4级。
方法
利用公开数据进行在线搜索，以确定在2017年4月1日至2021年3月31日期间遭受ACL、跟腱或腘绳肌腱损伤的所有NFL球员。收集的数据包括球员特征以及受伤时的职业生涯和赛季工作量。
结果
2020年NFL赛季中，跟腱损伤数量（27例对20例；P = 0.024）和腘绳肌腱损伤数量（186例对149例；P < 0.001）分别显著高于2017年至2019年赛季的平均水平。然而，ACL损伤数量保持不变（43例对46例；P = 0.175）。2017年至2019年赛季超过一半（52.9%）的ACL损伤发生在季前赛，而2020赛季大部分损伤（34.9%）发生在第1至4周。与2017年至2019年赛季相比，2020年NFL赛季中遭受ACL、跟腱或腘绳肌腱损伤的球员，在收集的球员特征或职业生涯工作量变量方面没有显著差异。
结论
与2017年至2019年赛季相比，在2020年NFL赛季中，跟腱和腘绳肌腱损伤数量增加，而ACL损伤数量保持不变。2020年NFL赛季前4场比赛期间发生的损伤情况与往年季前赛较高的受伤率一致。
