The purpose of this study was to build on current understanding of Achilles tendon (AT) ruptures in football through the examination of lower extremity injury rates (IR) in the season prior to AT rupture.
An online review was conducted to document AT ruptures in the National Football League (NFL) from the 2010-11 through 2016-17 seasons. Player-specific information was gathered through the online search, injury reports, or video analysis. Injury incidence was recorded for each season. Descriptive statistics were calculated for all variables. IRs per 1000 athlete-exposures with 95% confidence intervals (CI) were established. Injury rate ratios (IRR) with 95% CI were calculated to evaluate differences in IR with statistical significance established at p < 0.05.
From the 2010-11 to 2016-17 NFL seasons, 109 AT ruptures were identified. 36 athletes participated in the NFL the season prior and sustained a total of 40 injuries. Thirty-two (32/40, 80%) of the injuries involved the lower extremity. The most frequent body parts injured in the NFL season prior to AT rupture were the knee (n = 8, 22.5%), upper leg and thigh (n = 7, 17.5%), lower leg and shin (n = 5, 12.5%), and ankle (n = 5, 12.5%). The overall IR for the AT rupture group was not significantly different than the NFL group (IRR: 0.94, 0.68-1.31 95% CI, p = 0.73). The AT rupture group demonstrated a significantly increased rate of foot injuries compared to the NFL cohort (IRR: 2.58, 1.16-5.77 95% CI, p = 0.02).
There was an increased identified incidence of AT ruptures in the NFL from 2010 to 2017 compared to AT ruptures reported from 1997 to 2002. There was no significant difference in lower extremity IR the season prior to AT rupture. Only foot injuries demonstrated an increased IR the season prior to AT rupture compared to an NFL cohort. Eleven athletes sustained 2 AT ruptures and all 11 players sustained the subsequent AT rupture to the contralateral limb.
本研究的目的是通过检查跟腱（AT）断裂前一个赛季的下肢损伤率（IR），加深对足球运动中跟腱断裂的当前认识。
进行了一项在线回顾，以记录2010 - 11赛季至2016 - 17赛季美国国家橄榄球联盟（NFL）中的跟腱断裂情况。通过在线搜索、损伤报告或视频分析收集球员特定信息。记录每个赛季的损伤发生率。计算所有变量的描述性统计数据。确定每1000名运动员暴露次数的损伤率（IR）及其95%置信区间（CI）。计算损伤率比（IRR）及其95%CI，以评估损伤率的差异，设定p < 0.05为具有统计学意义。
在2010 - 11赛季至2016 - 17赛季的NFL中，共确定了109例跟腱断裂。36名运动员在前一个赛季参加了NFL比赛，共遭受了40次损伤。其中32次（32/40，80%）损伤涉及下肢。在跟腱断裂前的NFL赛季中，最常受伤的身体部位是膝盖（n = 8，22.5%）、大腿（n = 7，17.5%）、小腿（n = 5，12.5%）和脚踝（n = 5，12.5%）。跟腱断裂组的总体损伤率与NFL组无显著差异（IRR：0.94，95%CI为0.68 - 1.31，p = 0.73）。与NFL队列相比，跟腱断裂组的足部损伤率显著增加（IRR：2.58，95%CI为1.16 - 5.77，p = 0.02）。
与1997年至2002年报告的跟腱断裂相比，2010年至2017年NFL中跟腱断裂的发生率有所增加。在跟腱断裂前一个赛季，下肢损伤率无显著差异。与NFL队列相比，只有足部损伤在跟腱断裂前一个赛季的损伤率有所增加。11名运动员发生了2次跟腱断裂，所有11名运动员随后对侧肢体发生了跟腱断裂。
