Bone contusions are an important ancillary finding of many knee injuries. Not only are they a source of pain, they may suggest a mechanism of injury or a specific derangement of the knee joint. We have encountered a small number of patients being evaluated for anterior cruciate ligament (ACL) tears with unexplained patellar and tibial edema at magnetic resonance (MR) imaging. We present three individuals with contusions of the inferior patella with a corresponding contusion of the anteromedial tibial plateau. Internal derangements in these patients were similar to other individuals with acute ACL tears, however osseous contusions were more widespread. In conclusion, patellotibial contusions are rare and may indicate an injury with forces greater than usually encountered in most ACL tears. A careful search for uncommon associated injuries is prudent in these high-energy knee injuries.
骨挫伤是许多膝关节损伤的重要伴随发现。它们不仅是疼痛的来源，还可能提示损伤机制或膝关节特定的紊乱。我们遇到少数接受前交叉韧带 (ACL) 撕裂评估的患者，磁共振 (MR) 成像显示髌腱和胫骨不明原因的肿胀。我们介绍了 3 名髌部下极骨挫伤的患者，相应的前内侧胫骨平台也有骨挫伤。这些患者的内部紊乱与其他急性 ACL 撕裂患者相似，但骨挫伤更为广泛。总之，髌腱骨挫伤较为罕见，可能表明损伤的力量大于大多数 ACL 撕裂时通常遇到的力量。在这些高能量膝关节损伤中，仔细寻找不常见的相关损伤是谨慎的。
