摘要
目的探讨胫骨平台后倾角(posterior tibial slope,PTS)大小与健康人群前交叉韧带(anterior cruciate ligament,ACL)灰度、体积及横截面积的关系。方法2020年1~8月招募健康受试者212例,男、女各106例。年龄30~60岁,(39.3±7.3)岁。BMI 17.7~36.3,(24.3±3.3)。通过磁共振成像(magnetic resonance imaging,MRI)及3D重建模型测量胫骨平台内、外侧后倾角及ACL灰度、体积和横截面积。对比男、女性测量结果,分析胫骨平台内、外侧后倾角与ACL灰度、体积和横截面积的相关性。结果女性胫骨平台外侧后倾角大于男性[(8.0±3.8)°vs.(6.3±4.1)°,t=-3.068,P=0.002],ACL体积和横截面积小于男性[(1339.4±458.4)mm 3 vs.(1699.6±468.6)mm 3,t=5.658,P=0.000;(36.4±13.0)mm 2 vs.(45.2±14.8)mm 2,t=4.614,P=0.000],男、女性内侧后倾角和ACL灰度无统计学差异(P>0.05)。男、女性健康受试者内、外侧后倾角与ACL灰度、体积和横截面积的相关性均无统计学意义(P>0.05)。结论在健康人群中,胫骨平台后倾角与前交叉韧带的灰度、体积和横截面积均无相关性。健康女性的外侧后倾角大于男性。
Objective To investigate the relationship between the posterior tibial slope(PTS)and the gray scale,volume and cross-sectional area of anterior cruciate ligament(ACL)in healthy people.Methods A total of 212 healthy subjects(including 106 males and 106 females),aged from 30 to 60 years old(mean,39.3±7.3 years old),with BMI from 17.7 to 36.3(mean,24.3±3.3),recruited from January 2020 to August 2020 were selected to measure the lateral and medial tibial slope and the gray scale,volume and cross-sectional area of ACL through MRI images and 3D models.The measured results were compared between the male and female subjects,and the relationships between the PTS and the gray scale,volume and cross-sectional area of ACL were analyzed.Results The lateral tibial slope of females was greater than that of males[(8.0±3.8)°vs.(6.3±4.1)°,t=-3.068,P=0.002].The ACL volume and cross-sectional area of females were smaller than those of males[(1339.4±458.4)mm 3 vs.(1699.6±468.6)mm 3,t=5.658,P=0.000;(36.4±13.0)mm 2 vs.(45.2±14.8)mm 2,t=4.614,P=0.000].There was no statistical difference in medial tibial slope and ACL gray scale between males and females(P>0.05).In male and female subjects,there was no correlation between PTS and ACL gray scale,volume and cross-sectional area(P>0.05).Conclusion In healthy people,PTS has no correlation with the gray scale,volume or cross-sectional area of ACL.LTS in healthy women is greater than that in healthy men.
