| 目的 对比复发性髌骨脱位患者在术前及术后股内斜肌的形态学变化。方法 回顾性分析2021年1月至2023年10月因复发性髌骨脱位于云南省滇南中心医院（红河哈尼族彝族自治州第一人民医院）关节外科就诊的30例患者的MRI图像，测量术前和术后6个月的冠状面股内斜肌与内收肌结节距离、矢状面股内斜肌与内收肌结节距离、股内斜肌与股骨纵轴夹角、股内斜肌的横截面积比等相关形态学参数并进行术前与术后对比。结果 术后6个月冠状面股内斜肌与内收肌结节距离［（26.19±8.44）mm］较术前［（36.35±9.47）mm］明显缩短，差异有统计学意义（P＜0.05）；术后6个月矢状面股内斜肌与内收肌结节距离［（8.31±3.3）mm］较术前［（11.37±4.38）mm］明显缩短，差异有统计学意义（P＜0.05）；术后6个月股内斜肌与股骨纵轴夹角［（27.51±8.9）°］较术前［（34.53±13.13）°］明显缩小，差异有统计学意义（P＜0.05）；术后6个月股内斜肌的横截面积比［（0.036±0.013）mm2］较术前［（0.049±0.022）mm2］缩小，差异有统计学意义（P＜0.05）。术后6个月股内斜肌的横截面积比显著低于术前，可能与术后肌肉萎缩未完全恢复有关。结论 通过MPFL重建治疗复发性髌骨脱位可有效改善股内斜肌的形态学。 |

| Objective To compare the morphological changes of vastus medialis oblique muscle in patients with recurrent patellar dislocation before and after operation.Methods MRI images of 30 patients with recurrent patellar dislocation admitted to the department of joint surgery at the Southern Central Hospital of Yunnan Province (The First People's Hospital of Honghe State) between January 2021 and October 2023 were analysed retrospectively. The following measurements were taken before and 6 months after surgery: The distance between the vastus medialis oblique muscle and the adductor muscle tubercle on the coronal plane; the distance between the vastus medialis oblique and the adductor muscle tubercle on the sagittal plane; the angle between the vastus medialis oblique and the longitudinal axis of the femur; and the cross-sectional area ratio of the vastus medialis oblique.Results Six months after the operation, the distance between the vastus medialis oblique muscle and the adductor tubercle in the coronal plane [(26.19±8.44) mm] was significantly shorter than that before operation [(36.35±9.47) mm], and this difference was statistically significant (P<0.05). The sagittal distance between the vastus medialis oblique muscle and the adductor tubercle [(8.31±3.3) mm] was significantly shorter than that before operation [(11.37±4.38) mm], and the difference was statistically significant (P<0.05). The angle between the vastus medialis oblique muscle and the femoral longitudinal axis [(27.51±8.9)°] was significantly smaller than that before operation [(34.53±13.13)°] (P<0.05). The cross-sectional area ratio of the vastus medialis oblique muscle [(0.036±0.013) mm²] was smaller than that before operation [(0.049±0.022) mm²], and the difference was statistically significant (P<0.05). This may be related to incomplete recovery from muscle atrophy after the operation.Conclusion MPFL reconstruction in the treatment of recurrent patellar dislocation can effectively improve the morphology of the vastus medialis oblique. |
