目的：探讨膝关节损伤的MRI特点、病理基础及临床意义。方法：分析52例膝关节损伤的MRI资料。结果：半月板损伤45例，MRI表现为黑色的半月板内出现结节状、线状、放射状裂隙样异常高信号，延伸达或未及关节软骨面两种。前交叉及后交叉韧带损伤24例，MRI表现为在条索状黑色韧带影中出现短T1长T2异常高信号，韧带变形，呈波浪状或不连续，胫骨移位。内、外侧副韧带损伤28例，表现为信号增高，形态增粗，边缘模糊。隐匿性骨折8例，表现为干骺端边界模糊的片状T1低信号影，T2信号多样。讨论：MRI对膝关节半月板、韧带损伤及隐匿性骨折的诊断有重要的临床意义，可对治疗方案的选择提供详尽的依据。

Objective: To study the MRI findings and its pathological morphology and clinical significance of the knee injury.Methods:52 cases with knee injury were performed MR scans. Results: Meniscal tear was diagnosed in 45 of 52 cases by MRI.It showed nodular,linear, radial fissure-shaped hyperintensity signal in the hypointense meniscus. Anterior or posterior cruciate ligament injury showed short T1 and long T2 signal intensity, and its shape appeared wave-like or discontinuous in 24 cases. Medial and lateral collateral ligament injuries in 28 cases demonstrated hyperintensity on T2WI, thickening in shape and marginal haziness. 8 cases of periarticular occult bony fracture showdd hazy patchy hypointensity signal of the border of diaphyseal epiphysis on T1WI and variable intensity on T2WI. Conclusion:MRI plays an important role in evaluation of knee injuries and provides detailed information for treatment plarning.
