摘要
目的探讨3.0 T磁共振(magnetic resonance imaging,MRI)腹部线圈在双膝关节骨性关节炎(knee osteoarthritis,KOA)伴内侧半月板突出上的应用价值。方法回顾性收集经手术、关节镜和临床证实的双膝KOA病例。将双膝KOA伴双膝半月板突出组(A组)、单膝半月板突出组(B组)、双膝均半月板突出组(C组)的临床特点进行比较分析。将伴半月板突出的膝关节(研究组)的影像学资料,与不伴半月板突出(对照组)作比较,着重分析半月板损伤、软骨损伤、韧带损伤特点,分析KOA伴内侧半月板突出与影像学特征的关系。结果62例双膝KOA患者,37例患者双膝内侧半月板均突出,11例患者单膝内侧半月板突出,14例患者双膝均无内侧半月板突出,三组患者性别、年龄均无明显差异。124例膝关节,85例膝关节伴半月板突出,在胫股关节软骨损伤上与39例不伴半月板突出膝关节比较,差异具有统计学意义(P<0.05)。结论应用腹部线圈一站式完成双膝关节扫描,对于双膝KOA病人,不仅可以发现半月板突出情况,而且可以诊断软骨、韧带和半月板的损伤情况。KOA伴半月板突出的膝关节,与不伴半月板突出的膝关节比较,胫股关节软骨损伤可作为其特征性的影像学表现。
Objective To investigate the value of 3.0T MRI abdominal coils in bilateral knee osteoarthritis with medial meniscal protrusion.Methods Retrospective collection of surgically,arthroscopically and clinically confirmed cases of osteoarthritis in both knees.The clinical characteristics of the group with osteoarthritis of both knees with meniscus herniation(Group A),the group with meniscus herniation of one knee(Group B)and the group with meniscus herniation of both knees(Group C)were compared and analysed.The imaging data of the knee with meniscal herniation(study group)was compared with that of the knee without meniscal herniation(control group),focusing on the characteristics of meniscal damage,cartilage damage and ligament damage,and analysing the relationship between osteoarthritis of the knee with medial meniscal herniation and the imaging features.Results Of the 62 patients with bilateral knee osteoarthritis,37 patients had a prominent medial meniscus in both knees,11 patients had a prominent medial meniscus in one knee and 14 patients did not have a prominent medial meniscus in both knees;there were no significant differences between the three groups in terms of gender and age.Of 124 knees,85 knees with meniscal herniation were statistically significant in terms of tibial and femoral cartilage damage compared to 39 knees without meniscal herniation(P<0.05).Conclusion A one-stop scan of both knees is completed using the abdominal coil,and in patients with osteoarthritis of both knees,not only can meniscal herniation be detected,but also damage to cartilage,ligaments and menisci can be diagnosed.Knee with osteoarthritis of the knee with meniscus protrusion,compared to knee without meniscus protrusion.Cartilage damage to the tibia and femur can be a characteristic imaging feature.
