Describe the frequency and severity of knee ligament sprains diagnosed by MRI in athletes participating at the 2016 Summer Olympic Games, their association with certain sports and assess correlations with additional knee structural injury.
All knee MRIs performed in the Olympic Village and polyclinics during the 2016 Olympics were retrospectively, blindly reviewed for ligament sprains and associated knee injuries. In addition to the absence or presence of these abnormalities, athletes were stratified by age, gender and sport.
11,274 athletes participated in the 2016 Olympic Games: 113 athletes received at least one knee MRI with some having bilateral or repeat MRI on the same knee. Anterior cruciate and medial collateral ligament (ACL/MCL) sprains were most common, accounting for 32 of the 43 sprains (74.4%). Wrestling (10), hockey (7), athletics (7), and judo (5) accounted for over half of ligament sprains. ACL sprains showed a significant positive correlation with medial, lateral meniscal tears and bone contusions. The positive correlation between posterior cruciate ligament (PCL) sprains with MCL/lateral collateral ligament sprain, and popliteus tendon tear was statistically significant with 50% of total PCL sprains occurring in hockey. When athletes were stratified by gender, ligament sprains had a similar occurrence and distribution between men and women.
Knee ligament sprains, at the Rio 2016 Games, were most common in wrestling, hockey, athletics and judo with ACL and MCL sprains most frequent. Meniscal tears and bone contusions occurred often with ACL sprains. PCL sprains tended to be multi-ligamentous injuries. Sustained ligament sprains had similar occurrence between genders, while men had a peak incidence of sprains at a younger age and women at an older age.
描述2016年夏季奥运会参赛运动员中经磁共振成像(MRI)诊断的膝关节韧带扭伤的频率和严重程度,它们与某些运动项目的关联,并评估与膝关节其他结构损伤的相关性。
对2016年奥运会期间在奥运村和综合诊所进行的所有膝关节MRI检查进行回顾性、盲法分析,以确定韧带扭伤及相关的膝关节损伤情况。除了这些异常情况的有无,还根据年龄、性别和运动项目对运动员进行分层。
11274名运动员参加了2016年奥运会:113名运动员接受了至少一次膝关节MRI检查,其中一些人同一膝关节进行了双侧或重复MRI检查。前交叉韧带和内侧副韧带(ACL/MCL)扭伤最为常见,43例扭伤中有32例(74.4%)为此类。摔跤(10例)、曲棍球(7例)、田径(7例)和柔道(5例)占韧带扭伤的半数以上。ACL扭伤与内侧、外侧半月板撕裂及骨挫伤呈显著正相关。后交叉韧带(PCL)扭伤与MCL/外侧副韧带扭伤以及腘肌腱撕裂之间的正相关具有统计学意义,PCL扭伤总数的50%发生在曲棍球运动中。当按性别对运动员进行分层时,韧带扭伤在男性和女性中的发生率及分布相似。
在2016年里约奥运会上,膝关节韧带扭伤在摔跤、曲棍球、田径和柔道项目中最为常见,ACL和MCL扭伤最为频繁。ACL扭伤常伴有半月板撕裂和骨挫伤。PCL扭伤往往是多韧带损伤。持续性韧带扭伤在男女中的发生率相似,而男性扭伤的高峰年龄较小,女性则较大。
