Abstract：
OBJECTIVE: To analyze the MRI features, in particular bone bruises pattern, of Anterior Cruciate Ligament (ACL) injured footballers, and to correlate them with the characteristics of injury mechanism and situation obtained from direct video footage.
METHODS: Nineteen professional football (soccer) players that sustained ACL injury while playing during an official match of First League Championship were included in the study. The video of injury was obtained from the Television broadcast. Knee Magnetic Resonance (MRI) was obtained within 7 days from the injury. BB and meniscal lesions were analyzed on MRI, while a video-analysis of mechanisms of ACL injury and injury dynamic were assessed from the videos.
RESULTS: The most commonly involved Bone Bruise areas in the knee were the Posterior Lateral Tibial Plateau (LTp) in 16 cases (84%) and the Central Lateral Femoral Condyle (LFc) in 11 cases (58%). Three patients (16%) had bone bruise in the Posterior Medial Tibial Plateau (MTp) while none (0%) had bone bruise in the Medial Femoral Condyle. Based on the bone bruise pattern, 11 (58%) had simultaneous LFc and LTp and were defined \"Typical\" while 8 (42%) had other locations or no bone bruise and were defined \"Atypical\". 9 out of 11 injuries (82%) of athletes with \"Typical\" pattern occurred with a \"Pivoting\" action\", in contrast to only 1 case (12%) in those with \"Atypical\" bone bruise pattern (p = 0.0055). The most common situational mechanism pattern on video analysis was \"pressing\" (n = 7) accounting for the 47% of the \"indirect\" ACL injuries. In terms of movement pattern, ten injuries (52%) occurred during a \"Pivoting\" movement (7 pressing, 1 dribbling, 1 tackled, 1 goalkeeping), whereas the remaining were classified as \"Planting\" in four cases, \"Direct Blow\" in four cases and \"Landing\".
CONCLUSIONS: A well-defined and consistent bone bruise pattern involving the posterior tibial plateau and central femoral condyle of lateral compartment is present in footballers that sustained non-contact and indirect ACL injuries during pivoting with sudden change of direction/deceleration, while heterogeneous patterns were present in those with direct contact or injury mechanisms involving high horizontal velocity.
METHODS: Level IV.

摘要：
目的：分析MRI特征，特别是骨头瘀伤，前交叉韧带（ACL）受伤的足球运动员，并将它们与从直接录像中获得的损伤机制和情况的特征相关联。
方法：本研究包括19名职业足球（足球）运动员在第一联赛的正式比赛中受到ACL损伤。受伤的视频是从电视广播中获得的。在损伤后7天内获得膝关节磁共振(MRI)。在MRI上分析BB和半月板病变，同时从视频中评估了ACL损伤机制和损伤动态的视频分析。
结果：膝关节最常见的骨瘀伤区是胫骨后外侧平台（LTp）16例（84％）和股骨中央外侧髁（LFc）11例（58％）。三名患者（16％）在胫骨后内侧高原（MTp）有骨瘀伤，而在股骨内侧没有（0％）有骨瘀伤。根据骨头瘀伤的图案，11例（58％）同时具有LFc和LTp，被定义为“典型”，而8例（42％）具有其他位置或没有骨瘀伤，被定义为“非典型”。11例受伤中的9例（82％）具有“典型”模式的运动员发生在“旋转”动作中，相比之下，只有1例(12%)患有“非典型”骨瘀伤模式(p=0.0055)。视频分析中最常见的情境机制模式是“按压”（n=7），占“间接”ACL损伤的47％。就运动模式而言，在“旋转”运动中发生了10人受伤(52%)(7按，1运球，1解决，1个守门员），而其余的在四种情况下被归类为“种植”，四种情况下的“直接打击”和“着陆”。
结论：足球运动员中存在明确且一致的骨挫伤模式，涉及胫骨后平台和外侧室的股骨中央髁，在旋转过程中遭受非接触和间接ACL损伤，并突然改变方向/减速，而那些具有直接接触或涉及高水平速度的损伤机制的人存在异质模式。
方法：四级。
