Magnetic resonance imaging of the knees of 98 consecutive patients with clinically diagnosed anterior cruciate ligament injuries revealed 47 patients (48%) with focal signal abnormalities consistent with the diagnosis of a "bone bruise." Seventy-one percent of the magnetic resonance images taken within 6 weeks of injury demonstrated a bone bruise, whereas no scans done longer than 6 weeks after injury showed a bruise (P < 0.0001). Also significant was the tendency for lesions to be located in the lateral compartment (P < 0.0001). In the sagittal plane, lesions were most likely to be in the middle third of the lateral femoral condyle and the posterior third of the lateral tibial plateau (P < 0.0001). In 31 patients evaluated arthroscopically, there was no correlation between the presence or location of a bone bruise and articular alterations or meniscal tears observed at surgery.
对98例临床诊断为前交叉韧带损伤的连续患者的膝关节进行磁共振成像检查,发现47例患者(48%)存在与“骨挫伤”诊断相符的局灶性信号异常。受伤后6周内进行的磁共振成像检查中,71%显示有骨挫伤,而受伤6周后进行的扫描均未显示有挫伤(P<0.0001)。损伤倾向于位于外侧间室也具有显著意义(P<0.0001)。在矢状面上,损伤最常位于外侧股骨髁的中三分之一和外侧胫骨平台的后三分之一(P<0.0001)。在31例接受关节镜检查的患者中,骨挫伤的存在或位置与手术中观察到的关节改变或半月板撕裂之间没有相关性。
