To determine whether there is a relationship between the size of the bone bruise volume after an acute anterior cruciate ligament (ACL) rupture and the presence of meniscal tears in the medial and lateral compartment.
Following Institutional Review Board approval, 50 patients with an acute ACL rupture and MRI imaging within 30 days of injury were identified. Two musculoskeletal radiologists evaluated the lateral and medial menisci and graded them as one of the following: no meniscal tear, tear of one meniscus (medial or lateral) or tear of both menisci (medial and lateral). Sagittal T2 fat-suppressed images were used to calculate bone bruise volume. The relationship between bone bruise volume and the presence of a meniscus tear was calculated.
Forty-three (86%) patients had a bone bruise, 16 (32%) patients had no tear, 7 (14%) patients had lateral meniscus tear, 13 (26%) patients had medial tear and 14 (28%) patients had medial and lateral tears. There was a statistically significant difference in femoral bone bruise volume when comparing no meniscal tear to medial and lateral tears as well as when comparing medial or lateral tears to medial and lateral tears.
There is a statistically significant relationship between femoral bone bruise volume and the presence of meniscal tears in ACL injury, especially in the setting of medial and lateral pathology.
Retrospective cohort study, Level III.
确定急性前交叉韧带（ACL）断裂后骨挫伤体积大小与内侧和外侧半月板撕裂之间是否存在关联。
经机构审查委员会批准，确定了50例急性ACL断裂且在受伤后30天内进行了MRI成像的患者。两名肌肉骨骼放射科医生对外侧和内侧半月板进行评估，并将其分级为以下情况之一：无半月板撕裂、一个半月板（内侧或外侧）撕裂或两个半月板（内侧和外侧）撕裂。矢状面T2脂肪抑制图像用于计算骨挫伤体积。计算骨挫伤体积与半月板撕裂之间的关系。
43例（86%）患者有骨挫伤，16例（32%）患者无撕裂，7例（14%）患者有外侧半月板撕裂，13例（26%）患者有内侧撕裂，14例（28%）患者有内侧和外侧撕裂。在比较无半月板撕裂与内侧和外侧撕裂时，以及比较内侧或外侧撕裂与内侧和外侧撕裂时，股骨骨挫伤体积存在统计学显著差异。
在ACL损伤中，股骨骨挫伤体积与半月板撕裂之间存在统计学显著关联，尤其是在内侧和外侧病变的情况下。
回顾性队列研究，III级。
