摘　　要：背景:传统的影像学检查方法在膝关节半月板损伤诊断方面有很大的局限性,难以检测膝关节半月板的全部情况。目的:以磁共振成像评价膝关节半月板损伤。方法:回顾性分析以往经临床治疗证实的膝关节半月板损伤患者,分析其磁共振成像征象的特征并分级,显示半月板受损情况,与关节镜或手术结果进行对照研究。结果与结论:膝关节半月板损伤的磁共振成像中,Ⅰ级表现为不与半月板关节面接触的点状或圆形高信号,Ⅱ级表现为半月板内出现水平或斜行的线样或条状高信号影,但未达到半月板关节面缘,Ⅲ级表现为半月板内线条样或复杂形态高信号影延伸至半月板的关节面,可伴有半月板形态的改变。磁共振成像作为一种无创性的检查手段,能清楚地显示半月板变性和撕裂,正确地诊断半月板损伤的部位、形态及严重程度,这对临床确定治疗方案有非常重要的指导价值。BACKGROUND：Conventional imaging method has significant limitations in the diagnosis of knee meniscus injury, which is difficult to detect the ful extent of the knee meniscus. OBJECTIVE：To evaluate the knee meniscus injury with magnetic resonance imaging. METHODS：The knee meniscus injury patients diagnosed with clinical treatment were retrospectively analyzed, and the characteristics of the magnetic resonance imaging were analyzed and graded. Then, the meniscus injury was analyzed and compared with the arthroscopic or surgical results. RESUTLS AND CONCLUSION：In the magnetic resonance imaging of knee meniscus injury, the Ⅰ level knee meniscus injury was presented as the punctate or round high signal that did not contacted with the surface of the meniscus, Ⅱ level knee meniscus injury was presented as the horizontal or oblique line or strip-like high signal in the meniscus, and Ⅲ level knee meniscus injury was presented as lines and complex high signal in the meniscus that extended to the articular surface of the meniscus, and accompanied with morphological changes of the meniscus. Magnetic resonance imaging, as a noninvasive checking method, can clearly show the meniscal degeneration and tearing, and correctly diagnosed the location, shape and severity of meniscus injury, which has significant guiding value in determine the clinical treatment options.
