目的：分析青少年急性髌骨脱位后骨软骨损伤的MRI特点。材料与方法对41例青少年急性髌骨脱位的MRI资料进行回顾性分析，所有患者均行常规MR矢状面、冠状面和横断面T1WI、T2WI、脂肪抑制FSE序列扫描，分析骨软骨损伤的特点。结果急性髌骨脱位后，41例青少年有37例(90.2%)出现骨软骨损伤，其中Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级骨软骨损伤的发生率分别为10.5%、12.2%、24.5%、52.6%。青少年髌骨侧、股骨侧、髌骨-股骨骨软骨损伤的发生率分别为32.4%、13.5%、54.0%。结论青少年骨软骨损伤以Ⅲ级、Ⅳ级多见，损伤部位以髌骨侧及多部位损伤常见。
目的：分析青少年急性髕骨脫位後骨軟骨損傷的MRI特點。材料與方法對41例青少年急性髕骨脫位的MRI資料進行迴顧性分析，所有患者均行常規MR矢狀麵、冠狀麵和橫斷麵T1WI、T2WI、脂肪抑製FSE序列掃描，分析骨軟骨損傷的特點。結果急性髕骨脫位後，41例青少年有37例(90.2%)齣現骨軟骨損傷，其中Ⅰ級、Ⅱ級、Ⅲ級、Ⅳ級骨軟骨損傷的髮生率分彆為10.5%、12.2%、24.5%、52.6%。青少年髕骨側、股骨側、髕骨-股骨骨軟骨損傷的髮生率分彆為32.4%、13.5%、54.0%。結論青少年骨軟骨損傷以Ⅲ級、Ⅳ級多見，損傷部位以髕骨側及多部位損傷常見。

Objective:To analyze MRI characteristics of osteochondral injury patterns in adolescents after acute lateral patellar dislocation. Materials and Methods:MR images of 41 adolescents after acute lateral patellar dislocation were retrospectively reviewed. Routine MR scanning was performed in axial, sagittal and coronal planes, including T1WI, T2WI and fat saturation sequence. Results: The prevalence rate of osteochondral injury was 90.2% (37/41) in adolescent group after acute lateral patellar dislocation. The prevalence rate ofⅠ,Ⅱ,Ⅲ,Ⅳdegree were 10.5%, 12.2%, 24.5%, 52.6% in adolescent group. The prevalence rate of osteochondral injury at patellar attachment, femoral attachment and both patellar-femoral attachment were 32.4%, 13.5%, 54.0%in adolescent group. Conclusion:Ⅲ,Ⅳinjury and at patellar attachment, both patellar-femoral attachment were most easily occurred in adolescents.
