摘　　要：目的探讨膝关节隐性骨折的MRI诊断及意义。方法 64例膝关节外伤后2周内X线检查阴性但局部症状明显的患者行MRI检查,其中15例行关节腔镜检查。结果 64例共89处隐性骨折,主要发生于股骨外侧髁及胫骨上端前部和外侧,其中20例伴交叉韧带、副韧带及半月板撕裂。结论 MRI能敏感显示创伤性膝关节隐性骨折,诊断准确,并能发现韧带、肌腱及软骨的损伤。对于疑有膝关节隐性骨折或软组织损伤者,MRI为首选检查手段。Objective To study the MRI diagnosis for occult fractures of knee joint.Methods 64 patients were X-ray negative, but the local symptoms were existed within 2 weeks after trauma. 15 patients had been performed arthroscopy.Results 89 subtle fractures were found in 64 cases in lateral femoral condyle, tibial anterior and lateral. Posterior cruciate ligament, collateral ligament and meniscus were torn in 20 cases.Conclusion MRI can be sensitive to show occult fractures of knee joint, with the more accuracy, and discover ligaments, tendons and cartilage damage. For those patients suspected occult fracture of knee joint or soft tissue injury, MRI is the preferred method to be chosen.
