目的：研究男性职业足球运动员连续18个赛季前后踝关节撞击综合征（AAIS和PAIS）的流行病学和回归特征。
方法：在2001-2002和2018-2019赛季之间，在不同的赛季中，有120支欧洲足球队被跟踪。在6754名独特的球员中分别记录了时间损失伤害和球员暴露。损伤发生率和负担报告为每1000小时的损伤次数和缺席天数，置信区间为95％（CI）。损伤严重程度报告为四分位距（IQR）的中位数缺失天数。
结果：在25,462例报告的伤害中，在77名球员中，93名（0.4％）被诊断为AAIS（38％）或PAIS（62％）。AAIS和PAIS在损伤特征方面相似，除了较高比例的AAIS逐渐发作（69％vs.47％；P=0.03）和再次受伤（31％vs.9%；P=0.01）。撞击综合征导致每1000小时0.03损伤（95％CI0.02-0.03）的总发生率和每1000小时0.4缺席日的损伤负担。PAIS发生率显着高于AAIS[0.02（95％CI0.002-0.03）与每1000小时损伤0.01（95%CI0.005-0.01）（RR=1.7）。AAIS的缺席时间明显长于PAIS[10（22）vs.6（11）天；P=0.023]。与急性发作的撞击相比，逐渐发作的撞击综合征的缺席时间更长[8（22）与5（11）天；P=0.014]。与训练相比，比赛的发生率更高，受伤负担更大：0.08vs.每1000小时伤害0.02（RR4.7），分别,和0.9vs.每1000小时不存在0.3天（RR2.5）。
结论：脚踝受伤在男子职业足球中很常见，脚踝撞击越来越被认为是常见的疼痛来源，有限的运动范围，和潜在的时间损失。在我们的研究中,踝关节撞击是时间损失的原因，占所有损伤的0.5%以下。PAIS比AAIS更频繁地被报道，但与PAIS相比,AAIS与更多的缺勤天数和更高的再损伤率相关.这项研究的发现可以帮助医生对职业足球中的踝关节撞击综合征进行最佳实践管理。

OBJECTIVE: To
study the epidemiology and return to play characteristics of anterior and posterior ankle impingement syndromes (AAIS and PAIS) over 18 consecutive seasons in male professional soccer players.
METHODS: Between the 2001-2002 and 2018-2019 seasons, 120 European soccer teams were followed prospectively for various seasons. Time loss injuries and player exposures were recorded individually in 6754 unique players. Injury incidence and burden were reported as the number of injuries and days absence per 1000 h with 95% confidence intervals (CIs). Injury severity was reported as median absence in days with the interquartile range (IQR).
RESULTS: Out of 25,462 reported injuries, 93 (0.4%) were diagnosed as AAIS (38%) or PAIS (62%) in 77 players. AAIS and PAIS were similar regarding injury characteristics except for a greater proportion of AAIS having a gradual onset (69% vs.47%; P = 0.03) and being re-injuries (31% vs. 9%; P = 0.01). Impingement syndromes resulted in an overall incidence of 0.03 injuries (95% CI 0.02-0.03) per 1000 h and an injury burden of 0.4 absence days per 1000 h. PAIS incidence was significantly higher than that for AAIS [0.02 (95% CI 0.002-0.03) vs. 0.01 (95% CI 0.005-0.01) injuries per 1000 h (RR = 1.7). The absence was significantly longer in AAIS than in PAIS [10 (22) vs. 6 (11) days; P = 0.023]. Impingement syndromes that presented with a gradual onset had longer absences in comparison to impingement with an acute onset [8 (22) vs. 5 (11) days; P = 0.014]. Match play was associated with a higher incidence and greater injury burden than training: 0.08 vs. 0.02 injuries per 1000 h (RR 4.7), respectively, and 0.9 vs. 0.3 days absence per 1000 h (RR 2.5).
CONCLUSIONS: Ankle injuries are frequent in men\'s professional soccer and ankle impingement is increasingly recognized as a common source of pain, limited range of motion, and potential time loss. In our
study, ankle impingement was the cause of time loss in less than 0.5% of all injuries. PAIS was more frequently reported than AAIS, but AAIS was associated with more absence days and a higher re-injury rate than PAIS. The findings in this
study can assist the physician in best practice management on ankle impingment syndromes in professional football.
