摘　　要：目的：外侧副韧带（lateral collateral ligament ，LCL ）和腘肌肌腱复合体（popliteus tendon ，POP-T ）是膝关节后外侧结构（posterolateral corner ，PLC）的主要组成结构，本文拟总结Ⅰ°～Ⅲ°PLC损伤各分度中两者的MR改变。方法急性膝关节外伤后体检提示Ⅰ°～Ⅲ°PLC损伤患者27例进行MR扫描，分析LCL和POP-T的MR改变，并与关节镜和手术所见对比。结果 Ⅰ°损伤15例：单纯LCL损伤11例，其中部分撕裂2例；POP-T水肿1例；LCL和 POP-T复合损伤3例。Ⅱ°损伤7例：LCL损伤3例，均为撕裂；复合损伤4例。Ⅲ°损伤5例：均为复合损伤，其中3例并骨折。各例关节镜检查并5例同时行开放手术，所见与MR基本相符。结论各分度PLC损伤中LCL和POP-T改变复杂多样，同分度PLC损伤中亦可不同。MR常规扫描具备评价LCL和POP-T不同程度损伤的能力，从而提高PLC损伤分度诊断准确性，以便指导治疗。Objective To study the MR findings of two major components of knee posterolateral corner （PLC）：lateral collateral ligament （LCL） and popliteus tendon （POP-T） in the degree Ⅰ°-Ⅲ°of PLC injury .Methods We analysed the MR findings in LCL and POP-T of 27 cases of Ⅰ°-Ⅲ°of PLC injury revealed by physical examination after knee acute trauma .Results Totle 15 cases Ⅰ° of PLC injury included ：LCL injury alone were found in 11 cases ,which included partial tear in 2 cases ,POP-T edema in 1 case and the combined injury of LCL and POP-T in 3 cases .Totle 7 cases of Ⅱ° PLC injury included LCL tear alone in 3 cases and combined injury in 4 cases .Totle 5 cases of Ⅲ° PLC injury were all combined injury ,which included 3 cases accompanied by fracture .The findings in operation of Ⅱ° PLC injury were 2 cases and 3 cases of Ⅲ° PLC injury were corresponded to MR images .Conclusion The MR findings of LCL and POP-T in the Ⅰ°~Ⅲ° PLC injury were varied ,the imaging signs could be different in the same injury degree .MR can show the detail of LCL and POP-T injury and contribute to provide an accurate assessment of Ⅰ°-Ⅲ°PLC injury ,which provide more information for clinical treatment .
