摘要
目的:探讨膝关节软骨损伤的MRI表现,以提高对软骨损伤的认识及诊断能力。材料与方法:回顾性分析经关节镜或手术证实的膝关节软骨损伤21例,对其MRI表现进行总结分析,包括关节软骨、软骨下低信号线及软骨下骨的改变,并与关节镜和手术对照分析。结果:本组病例共23处关节软骨损伤。分布:髌骨6处,股骨外侧髁7处,股骨内侧髁7处,胫骨平台3处。关节软骨损伤表现:裂隙状骨折4例,软骨局部缺损10例,软骨全层缺损9例。其他:关节内软骨游离体2例,软骨损伤附近骨挫伤、水肿20例,股骨内外髁骨折3例,胫骨平台骨折2例。结论:MRI能准确显示膝关节软骨损伤的部位、范围和类型,从而对临床治疗方案的选择提供重要的依据。
Purpose： To investigate the value of MR imaging of cartilage fracture of the knee joint, as well as in evaluation of clinical significance. Materials and Methods： The MRI changes of cartilage, subcartilage low signal line and sub- cartilage bone were analysed retrospectively in 21 patients with acute cartilage fracture confirmed by arthroscopy. And every manifestation on MRI and that of arthroscopy and operation was compared. Results： twenty-three sites of 21 patients include 6 patella, 7 femoral lateral condyle, 7 femoral medial condyle and 3 tibial plateau. Three types pure cartilage fracture were observed, fissuring fracture in 4 sites, superficial defect of the cartilage in 10 sites, totally defect of the cartilage in 9 sites. Corpus liberum was found in 2 patients＇ knee joints by MRI. Bone bruise was detected in 20 patients, and subcartilage low signal lines were normal. Conclusion： MRI is the best non-invasive method for studying cartilage fracture, can show the position, extension and types of the cartilage fracture of the knee joint and has important guiding role for clinical treatment options.
