Bone bruise represents an entity of occult bone lesions that can occur in the knee, causing knee pain and tenderness clinically. The aim of this study was to investigate the incidence and pattern of bone bruising seen in the anterior cruciate ligament (ACL) injury cohort, the non-ACL injury cohort, and between both cohorts.
We reviewed 710 knee magnetic resonance imagings performed over a 6-month period. Eighty-eight patients with prior history of a knee injury were identified. The mechanism of injury and other clinical findings was noted.
Among these 88 patients, 58 patients had an associated ACL injury (31 had isolated ACL injuries; 27 had combined ACL and other ligamentous injuries). Among the 30 who had non-ACL injuries, 15 had either an MCL, LCL, or PCL injury. The remaining 15 patients had no associated ligament injury. With an ACL injury, the most common bone bruise sites are the lateral femur (74%) and lateral tibia (64%). Without an ACL injury, the pattern of bruising was more common in the lateral femur (69%) and medial tibia (37%).
Bone bruises are important as previous studies have shown that they can cause persistent knee pain. Our study has shown that there are differences in pattern of bone bruising in knee injuries with or without ACL injuries.
骨挫伤是一种隐匿性骨损伤，可发生于膝关节，临床上可导致膝关节疼痛和压痛。本研究的目的是调查前交叉韧带（ACL）损伤队列、非ACL损伤队列以及两个队列之间骨挫伤的发生率和模式。
我们回顾了在6个月期间进行的710例膝关节磁共振成像。确定了88例有膝关节损伤既往史的患者。记录损伤机制和其他临床发现。
在这88例患者中，58例伴有ACL损伤（31例为单纯ACL损伤；27例为ACL合并其他韧带损伤）。在30例非ACL损伤患者中，15例有内侧副韧带（MCL）、外侧副韧带（LCL）或后交叉韧带（PCL）损伤。其余15例患者无相关韧带损伤。ACL损伤时，最常见的骨挫伤部位是股骨外侧（74%）和胫骨外侧（64%）。无ACL损伤时，挫伤模式在股骨外侧（69%）和胫骨内侧（37%）更常见。
骨挫伤很重要，因为先前的研究表明它们可导致持续性膝关节疼痛。我们的研究表明，有或无ACL损伤的膝关节损伤中骨挫伤模式存在差异。
