摘要目的:探讨膝关节骨关节炎患者运用MRI发现膝关节各结构病变的价值以及与疼痛症状之间的关系。方法:搜集本院已确诊或拟诊为膝关节骨关节炎的患者28例(男12例,女16例,平均年龄61.4岁)共31个膝关节为研究对象,运用主诉疼痛分级法对疼痛程度进行分级。运用1.5T磁共振仪对上述膝关节行多序列扫描,观察各研究对象磁共振图像中各种病变的出现率。运用统计软件(SPSS13.0;SPSS,Chicago,Ⅲ)分别计算本研究对象中上述关节各种结构病变的出现率,并行多组独立样本间Fisher精确检验比较不同疼痛程度患者组间出现上述征象的差别,以P<0.05为差异有显著性意义。结果:所有31例膝关节骨关节炎患者中磁共振成像显示关节软骨异常、半月板异常、前交叉韧带异常、软骨下骨骨髓水肿样改变、骨赘形成、滑膜增厚、关节积液的出现率分别为37.1%、32.3%、38.7%、45.2%、100%、15.1%和67.7%。其中轻、重度疼痛患者两组间有无关节积液及关节积液Ⅰ级和Ⅱ级的出现率差异均有显著性意义(P=0.004,0.001)。结论:磁共振可对膝关节骨关节炎患者行全关节各结构的评价,能很好地显示关节多方面的病理改变。患者的疼痛症状与关节积液有关。 Objective：To study the joint lesions in knee osteoarthritis by MRI and analyze the relationship between these lesions and pain. Methods： A total of 28 patients （31 knees）with osteoarthritis were recruited to this study. The severity of the knee pain was assessed by VRS scores. Multi-sequence scans were performed by 1.5T MR for detecting abnormity of cartilage,menisci and anterior cruciate ligaments, bone marrow edema-like lesion, osteophytes, synovitis and joint effusion. MR findings were compared with the severity of pain with Fisher exact test by SPSS13.0. Results：Of the thirty-one eligible knees in this study, the abnormity of menisci and anterior crueiate ligaments, bone marrow edema-like lesion, osteophytes, synovitis and joint effusion were detected in 32.3 %,38.7 %, 45.2 %, 100%, 15.10% and 67.7 % of knees respectively. The difference in prevalence of joint effusion between mild pain group and severe pain group were of statistical significance （P= 0. 004,0. 001）. Conclusion： MRI can evaluate the whole ioint structure of knee in osteoarth, ritis and is able to show various pathologic changes clearly. The symptoms of pain are related with joint effusion.
