【摘要】 本文探讨磁共振成像(MRI)诊断中青年运动性半月板损伤程度及判断患者术后康复效果的价值。选取98例运动性半月板损伤患者进行回顾性研究，患者术前均接受了高频超声和MRI检查，所有患者均接受关节镜手术修复治疗。结果显示，MRI诊断膝关节半月板损伤的灵敏度为90.00%、特异度为88.16%,MRI诊断膝关节韧带损伤的灵敏度为76.79%、特异度为97.02%;术后3个月、6个月患者的膝关节半月板MRI损伤分级较手术前均显著降低，差异具有统计学意义(P<0.05);术后6个月患者的膝关节功能分级与MRI半月板恢复分级呈正相关(r=0.850,P<0.001)。MRI诊断中青年运动性半月板损伤具有较高的诊断学价值，同时可以对患者术后康复效果进行评价。更多还原

【Abstract】 This article investigated the value of magnetic resonance imaging(MRI) in diagnosing the degree of sports-induced meniscus injury in young and middle-aged patients and the postoperative rehabilitation effect of patients. A retrospective study was performed on 98 patients with sports-induced meniscus injury treated. All patients received high-frequency ultrasound and MRI examinations before surgery, and all patients received arthroscopic surgical repair. The results showed that the sensitivity and specificity of MRI in diagnosing knee meniscus injury by preoperative MRI were 90.00% and 88.16%, the sensitivity and specificity of knee ligament injury by MRI were 76.79% and 97.02% respectively. The MRI damage grade of knee meniscus at 3 months and 6 months after operation was significantly lower than that before operation, and the difference was statistically significant(P<0.05). 6 months after the operation, the knee joint function grade was positively correlated with MRI meniscus recovery grade(r=0.850, P<0.001). MRI has high diagnostic value in the diagnosis of young and middle-aged sports meniscus injury, and could also evaluate the postoperative rehabilitation effect of patients.更多还原
