PURPOSE This study aimed to describe the epidemiology of ACL tears in NCAA men's and women's sports. METHODS Injury and exposure data collected within the NCAA Injury Surveillance Program from 2014/2015 to 2018/2019 were analyzed. ACL tear frequencies, injury rates (IR), and injury proportions were used to describe injury incidence by sport, event type, injury mechanism, and injury history. Injury rate ratios (IRR) were used to examine differential injury rates, and injury proportion ratios (IPR) were used to examine differential distributions. RESULTS A total of 729 ACL tears were reported from 8,474,401 recorded athlete exposures (AE) during the study period (IR = 0.86 per 10,000 AE), and the competition-related ACL tear rate was higher than the practice-related rate (IRR = 5.52, 95% confidence interval [CI] = 4.75-6.39). Among men's sports, the highest overall ACL tear rate was observed in men's football (IR = 1.44 per 10,000 AE), whereas among women's sports, the highest overall rate was observed in women's soccer (IR = 2.60 per 10,000 AE). Among sex-comparable sports, ACL tear rates were higher in women's basketball, softball, and soccer, as compared with their men's counterparts. ACL tears were more prevalently attributed to player contact mechanisms in men's sports than women's sports (IPR = 1.73, 95% CI = 1.37-2.19), but more prevalently attributed to noncontact mechanisms in women's sports than men's sports (IPR = 1.17, 95% CI = 1.01-1.35). CONCLUSIONS ACL tear risk in women's sports continues to warrant attention and prevention efforts. Given the differential rates by event type, future research efforts may also evaluate initiatives to reduce competition-related injury burden in NCAA sports.

美国大学体育协会运动员前十字韧带撕裂的流行病学：2014/2015-2018/2019。


目的 本研究旨在描述 NCAA 男子和女子运动中 ACL 撕裂的流行病学。方法 对 2014/2015 年至 2018/2019 年 NCAA 伤害监测计划中收集的伤害和暴露数据进行分析。 ACL 撕裂频率、损伤率 (IR) 和损伤比例用于按运动、事件类型、损伤机制和损伤史描述损伤发生率。伤害率比（IRR）用于检查差异伤害率，伤害比例比（IPR）用于检查差异分布。结果 研究期间，记录的 8,474,401 名运动员暴露 (AE) 中总共报告了 729 例 ACL 撕裂（IR = 每 10,000 AE 0.86 例），并且与比赛相关的 ACL 撕裂率高于与练习相关的率（IRR = 5.52） ，95% 置信区间 [CI] = 4.75-6.39）。在男子运动中，男子足球的总体 ACL 撕裂率最高（IR = 1.44/10,000 AE），而在女子运动中，女子足球的总体 ACL 撕裂率最高（IR = 2.60/10,000 AE）。在性别可比较的运动中，女子篮球、垒球和足球的前十字韧带撕裂率高于男子。在男子运动中，ACL 撕裂比在女子运动中更普遍地归因于运动员接触机制（IPR = 1.73，95% CI = 1.37-2.19），但在女子运动中比男子运动中更普遍地归因于非接触机制（IPR = 1.17，95%） CI = 1.01-1.35）。结论 女子运动中 ACL 撕裂的风险仍然值得关注并采取预防措施。鉴于不同赛事类型的发生率存在差异，未来的研究工作还可能评估减少 NCAA 体育运动中与比赛相关的伤害负担的举措。
