退变性半月板损伤与下肢力线的相关性研究

Correlation of degenerative meniscus injury with lower limb alignment:a clinical report of 90 cases

目的 比较退变性内侧半月板损伤与外侧半月板损伤之间下肢力线差异,探究半月板损伤与下肢力线之间的关系。方法 收集2019年3月至2022年3月经关节镜手术治疗的退变性半月板损伤患者90例,其中男性45例,女性45例;年龄40~59岁,中位年龄52岁。内侧半月板损伤组47例,外侧半月板损伤组43例。在全长片上测量髋-膝-踝角(HKA角)并比较两组间差异。结果 内侧半月板损伤组与外侧半月板损伤组患者性别、年龄、下肢侧别、体质量指数、损伤部位、损伤类型差异无统计学意义。内侧半月板损伤组HKA角为(177.20±2.46)°,外侧半月板损伤组为(181.05±3.13)°,两组差异有统计学意义(P<0.01)。结论 退变性内侧半月板损伤与外侧半月板损伤之间HKA角存在差异,下肢力线与退变性半月板损伤存在关联。

Objective To compare the differences in lower limb force line between degenerative medial meniscus injuries and lateral meniscus injuries and investigate their correlation.Methods A total of 90 patients who underwent arthroscopic treatment for meniscal injuries between March 2019 and March 2022 were enrolled in the study.They were 45 males and 45 females,at a median age of 52 years(ranging from 40 to 59 years).Of these patients,47 had medial meniscus injuries,while 43 had lateral meniscus injuries.The hip-knee-ankle(HKA) angle was measured on full-length films,and the differences were compared between the 2 groups.Results There were no significant differences in terms of gender,age,lower limb laterality,body mass index,site of injury,and type of injury between the medial meniscus injury group and the lateral meniscus injury group.Statistical difference was observed in the mean HKA angle,with a value of(177.20±2.46)° in the medial meniscus injury group and of(181.05±3.13)° in the lateral meniscus injury group(P<0.01).Conclusion There is a significant difference in HKA angle between medial meniscus injury group and the lateral meniscus injury group.A correlation is found between lower limb alignment and degenerative meniscus injury.
