摘要:


文题释义:

胫骨平台后倾角:胫骨平台关节面与胫骨纵轴并不垂直,而是成一定角度向后下倾斜,该角度即为胫骨平台后倾角,胫骨平台后倾角的增大可能与前交叉韧带损伤风险增加存在相关性。
胫骨内、外侧平台后倾角差值:胫骨内、外侧平台后倾角并不完全一致,胫骨内侧平台后倾角变化范围超过20°,胫骨外侧平台后倾角变化范围超过12°,两者之间的差异即胫骨内、外侧平台后倾角差值,该值的大小影响胫骨与股骨相对旋转运动。

背景:相关研究表明前交叉韧带的损伤可能与胫骨近端解剖学形态有关,而胫骨平台后倾角作为膝关节的解剖因素之一,有关其与前交叉韧带损伤相关性的研究成为热点。
目的:分析胫骨平台内、外侧后倾角大小及其差值与前交叉韧带损伤的相关性。
方法:回顾性分析成都市第二人民医院314例患者的膝关节MRI影像,根据前交叉韧带影像学表现分为正常组123例、前交叉韧带部分损伤组107例、前交叉韧带完全损伤组84例,测量3组之间胫骨内、外侧平台后倾角及两者差值,分析前交叉韧带损伤的影响因素。
结果与结论:①314例患者中,男性与女性间胫骨内、外侧平台后倾角及其差值比较差异无显著性意义(P > 0.05);②前交叉韧带部分损伤组与前交叉韧带完全损伤组胫骨内、外侧平台后倾角均大于正常组(P < 0.05),3组间胫骨内、外侧平台后倾角差值比较差异无显著性意义(P > 0.05);③二分类logistic回归分析表明,胫骨内侧平台后倾角是前交叉韧带损伤的独立危险因素(P < 0.05);ROC曲线表明,内胫骨侧平台后倾角对前交叉韧带损伤的诊断阈值为10.50°,曲线下面积AUC=0.676[95%CI(0.618,0.735),P < 0.001],灵敏度为55.5%,特异度为71.5%;④结果显示,前交叉韧带损伤的患者胫骨内、外侧平台后倾角增大,但两者差值大小与正常对照组无明显差异;胫骨内侧平台后倾角可能是前交叉韧带损伤风险的预测指标,胫骨内侧平台后倾角越大前交叉韧带越容易发生损伤。

Abstract: BACKGROUND: Related studies suggest that the anatomical morphology of the proximal tibia may be correlated with the injury of the anterior cruciate ligament. As one of the anatomical factors of the knee joint, the research on the relationship between the posterior tibial slope and anterior cruciate ligament injury has become a hotspot.  
OBJECTIVE: To analyze the correlation of medial and lateral posterior tibial slope with anterior cruciate ligament injury.
METHODS: The magnetic resonance imaging images of knee joint of 314 patients in Chengdu Second People’s Hospital were retrospectively analyzed. According to the anterior cruciate ligament imaging findings, there were 123 patients in the normal control group, 107 patients in the partial injury group and 84 patients in the complete injury group. The medial and lateral posterior tibial slope and the differences between medial and lateral compartment of the three groups were measured in the three groups to analyze the influencing factors of anterior cruciate ligament injury.  
RESULTS AND CONCLUSION: (1) There was no statistical difference in the medial and lateral posterior tibial slope and the differences between medial and lateral compartment between male and female in 314 patients (P > 0.05). (2) The medial and lateral posterior tibial slope in the group with partial anterior cruciate ligament injury and complete anterior cruciate ligament injury was higher than that in the normal group (P < 0.05). The difference of medial and lateral posterior tibial slope was not significantly different among the three groups (P > 0.05). (3) Binary Logistic regression analysis showed that the medial posterior tibial slope was an independent risk factor for anterior cruciate ligament injury (P < 0.05). ROC curve showed that the diagnostic critical value of medial posterior tibial slope was 10.50°, area under curve AUC=0.676 [95%CI: 0.618,0.735, P < 0.001]; sensitivity was 55.5%; specificity was 71.5%. (4) The results indicate that the medial and lateral posterior tibial slope increased in patients with anterior cruciate ligament injury, but the difference between the two was not significantly different from that of the normal control group. The medial posterior tibial slope may be a predictor of the risk of anterior cruciate ligament injury. The greater the medial posterior tibial slope, the greater the possibility of anterior cruciate ligament injury.

Key words: medial posterior tibial slope, lateral posterior tibial slope, anterior cruciate ligament injury, magnetic resonance imaging, knee joint
