青少年急性髌骨外侧脱位后内侧髌股韧带损伤的MRI诊断分析

MRI Diagnosis of Medial Patellofemoral Ligament Injury After Acute Lateral Patellar Dislocation in Adolescents

目的:对青少年急性髌骨外侧脱位后内侧髌股韧带损伤的MRI诊断进行分析。方法:选取66例2022年8月~2023年8月于本院收治的急性髌骨外侧脱位后内侧髌股韧带损伤患者,根据患者年龄,将其分为青少年组和成人组,各33例患者。所有患者均进行MRI检查,对比两组患者诊断情况。结果:两组完全撕裂、部分撕裂、韧带损伤程度、体部损伤,联合损伤等相关指标,差异不明显,无统计学意义(P>0.05),青少年组髌骨侧损伤发生率为63.64%,股骨侧损伤发生率为27.27%,成人组髌骨侧损伤发生率为51.52%,股骨侧损伤发生率为39.39%,两组差异明显,有统计学意义(P<0.05)。结论:针对青少年急性髌骨外侧脱位后内侧髌股韧带损伤,经MRI诊断结果显示,患者主要Ⅱ、Ⅲ级损伤为主,完全撕裂发生率高于部分撕裂发生率,损伤部位主要集中于髌骨侧,这对患者治疗具有重要作用。

Objective:To analyze the MRI diagnosis of medial patellofemoral ligament injury after acute lateral dislocation of patella in adolescents.Methods:66 patients with medial patellofemoral ligament injury after acute lateral patellar dislocation admitted to our hospital from August 2022 to August 2023 were selected and divided into adolescent and adult groups according to their age.33 patients each.All patients were examined by MRI,and the diagnosis of the two groups was performed.Results:There was no significant difference in related indicators such as complete tear,partial tear,ligament injury,body injury,and combined injury between the two groups(P>0.05).The incidence of patella injury was 63.64%in the adolescent group,27.27%in the femur side,and 51.52%in the adult group.The incidence of femur side injury was 39.39%,and the difference between the two was significant(P<0.05).Conclusion:For the medial patellofemoral ligament injury after acute lateral patellar dislocation in adolescents,MRI diagnosis results show that the patients are mainly grade II and III injuries,the incidence of complete tear is higher than that of partial tear,and the injury site is mainly concentrated on the patellar side,which has an important role in the treatment of patients.
