Purpose: 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.
Patients and Methods: 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.
Results: 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.
Conclusion: 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.

MRI 检测到 2016 年里约热内卢夏季奥运会运动员的膝关节韧带扭伤和相关的内部紊乱

目的:描述参加 2016 年夏季奥运会的运动员通过 MRI 诊断出的膝关节韧带扭伤的频率和严重程度,它们与某些运动的关联,并评估与额外膝关节结构性损伤的相关性。
患者和方法: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 进行了回顾性、盲法检查,以确定韧带扭伤和相关膝关节损伤。除了这些异常的不存在或存在之外,运动员还按年龄、性别和运动进行分层。
结果:11,274 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核磁共振检查,其中一些人在同一膝关节进行了双侧或重复核磁共振检查。前交叉韧带和内侧副韧带 (ACL/MCL) 扭伤最为常见,占 43 例扭伤中的 32 例(74.4%)。摔跤(10)、曲棍球(7)、田径(7)和柔道(5)占韧带扭伤的一半以上。ACL扭伤与内侧、外侧半月板撕裂和骨挫伤呈显着正相关。后交叉韧带 (PCL) 扭伤与 MCL/外侧副韧带扭伤和腘肌腱撕裂之间的正相关具有统计学意义,其中 50% 的 PCL 扭伤发生在曲棍球比赛中。当运动员按性别分层时,韧带扭伤的发生率和分布在男性和女性之间相似。
结论:在 2016 年里约奥运会上,膝关节韧带扭伤在摔跤、曲棍球、田径和柔道中最为常见,其中 ACL 和 MCL 扭伤最为常见。ACL 扭伤经常发生半月板撕裂和骨挫伤。PCL扭伤往往是多韧带损伤。持续性韧带扭伤在两性之间的发生率相似,而男性的扭伤发生率在年轻时达到峰值,而女性在年龄较大时发生。
