MRI诊断髌下脂肪垫损伤的价值

目的探讨膝关节髌下脂肪垫(infrapatellar fat pad,IFP)损伤的磁共振成像(MRI)特点及临床应用价值。方法回顾性分析我院经临床综合诊断或临床随访明确诊断为IFP损伤的111例患者,归纳总结其特征性MRI表现并分级。结果111例中,左膝57例,右膝39例,双膝15例。共126个膝关节根据IFP的信号、裂隙及形态改变进行损伤程度分级轻度54个(42.9%),中度43个(34.1%),重度29个(23.0%)。根据IFP损伤程度指导临床给予相应治疗,终止治疗4~8周随访。治疗前后膝关节VAS评分有显著差异(P<0.05)。结论MRI能准确评估IFP损伤部位及严重程度,为临床治疗提供影像学依据并有较好的指导作用。

Values of MRI in diagnosis of infrapatellar fat pad injury

Objective To investigate the features and clinical value of MRI in the diagnosis of infrapatellar fat pad(IFP)injury.Methods In this retrospective analysis,we included 111 patients diagnosed with IFP injury who were admitted to our hospital between April 2018 and April 2019.Then,we summarized the features of MRI together with the grade evaluation.Results Among the 111 cases,57 showed IFP injury in left knee,39 showed IFP injury in right knee(including 15 with injury in both knees).The injury grading was performed based on the IFP signals,cleft and profile of the 126 knees,including the mild in 54 cases,(42.9%),the moderate in 43(34.1%),and the severe in 29(23.0%).Treatment was given based on the IFP injury.The patients were followed up for at least 4~8 weeks after treatment.There were significant differences in the VAS score of the knee joints after treatment compared with the baseline levels(P<0.05).Conclusion MRI contributes to the evaluation of IFP injury position and severity,which can provide helpful information for the clinical treatment.
