青少年急性与慢性髌骨脱位后内侧髌股韧带损伤特点的性别差异

Gender differences in characteristics of medial patellofemoral ligament injury between acute and chronic patellar dislocation in adolescents

目的探讨青少年急性与慢性创伤性髌骨外侧脱位后内侧髌股韧带(MPFL)损伤的特点有无性别差异。方法回顾性分析2008年1月~2018年1月我院符合入选条件的161例青少年急性与慢性创伤性髌骨外侧脱位后内侧髌股韧带损伤患者的临床资料及MRI影像资料。MPFL损伤急性患者93例,MPFL慢性患者68例。均进行1年的随访,评估分析内侧髌股韧带的损伤程度、损伤部位情况。结果青少年男性和女性患者急性MPFL损伤分度和损伤部位的发生率比较差异无统计学意义(P>0.05)。在青少年慢性MPFL损伤分度方面,男性患者以Ⅲ°损伤为主,明显高于女性患者(P<0.05),而女性患者则以Ⅱ°损伤为主,明显高于男性患者(P<0.05),但男性和女性患者在Ⅰ°损伤比较差异无统计学意义(P>0.05)。在慢性MPFL损伤部位方面均以髌骨侧为主,男性和女性患者的损伤发生率比较差异无统计学意义(P>0.05)。结论青少年急性MPFL损伤分度和损伤部位,以及慢性MPFL损伤部位的MRI特点无性别差异,但在慢性MPFL损伤分度中男性患者以Ⅲ°损伤为主,而女性患者则以Ⅱ°损伤为主。

Objective To explore whether there are gender differences in the characteristics of medial patellofemoral ligament(MPFL)injury after acute and chronic traumatic lateral dislocation of the patella.Methods The clinical data and MRI imaging data of 161 adolescent patients with medial patellofemoral ligament injury after acute and chronic traumatic lateral patellar dislocation in our hospital from January 2008 to January 2018 were retrospectively analyzed.93 patients with acute MPFL injury and 68 patients with chronic MPFL injury.All patients were followed up for 1 year to evaluate the injury degree and injury site of the medial patellofemoral ligament.Results There was no statistical significance in the degree and incidence of acute MPFL injury in male and female subjects(P>0.05).In terms of the degree of chronic MPFL injury in males,Ⅲ°lesion was predominant,and significantly higher than that in females(P<0.05),while in females,Ⅱ°lesion was predominant,and significantly higher than that in males(P<0.05).However,there was no statistical significance between males and females inⅠ°lesion(P>0.05).In terms of injury sites of chronic MPFL,there was no statistical significance in the incidence of injury between male and female patients(P>0.05).Conclusion There is no gender differences in the MRI characteristics of acute MPFL injury degree and injury sites in adolescents,and the chronic MPFL injury site,but there is a difference in the chronic MPFL injury degree.Male patients mainly haveⅢ°injuries,while female patients haveⅡ°injuries mainly.
