【摘要】：目的探究交叉韧带的松紧度与半月板损伤的相关性,从解剖学上探索半月板损伤的影响因素,为预测和诊断半月板损伤提供新的依据。方法收集南方医科大学珠江医院2014年1月~2016年12月260例患者单膝关节伸直位的MRI资料。在各膝MRI相同矢状面分别测量前、后交叉韧带的长度a和p,及其起止点的距离la和lp。计算出交叉韧带松紧度系数R=(a+p)/(l_a+l_p)。用t检验比较各组患者间的差异性,用Spearman相关分析分别探讨松紧度系数与半月板损伤的相关性。结果 t检验:无论是否存在骨关节炎,半月板损伤组和无半月板损伤组的R值均存在显著差异性(P0.05)。Spearman相关性分析:无骨关节炎患者中rs=0.620,R值与半月板损伤存在较强的正相关性;有骨关节炎患者中r_s=0.313,R值与半月板损伤存在弱正相关性。结论交叉韧带松紧度与半月板损伤存在一定程度的相关性,特别在膝关节无骨关节炎的年轻患者中,韧带越松弛,半月板损伤越容易发生。但在膝关节有关节炎的老年患者中,交叉韧带的松紧程度并非半月板损伤的主要因素。
[Abstract]:Objective to explore the relationship between the tightness of cruciate ligament and meniscus injury, and to explore anatomically the influencing factors of meniscus injury. Methods MRI data of 260 patients with knee joint extension from January 2014 to December 2016 in Zhujiang Hospital of Southern Medical University were collected. Before the same sagittal plane measurement of MRI in each knee, the results were compared with those in the same sagittal plane. The length of the posterior cruciate ligament a and p, and the distance between the starting and ending points la and lp. the coefficient of cruciate ligament tightness was calculated, and the T test was used to compare the differences among the patients. The correlation between the coefficient of tightness and meniscus injury was investigated by Spearman correlation analysis. There was significant difference in R value between meniscus injury group and non-meniscus injury group. The correlation analysis showed that there was a strong positive correlation between Rsf0.620R and meniscus injury in patients without osteoarthritis. In patients with osteoarthritis, there was a weak positive correlation between the value of r / S 0.313 / r and meniscus injury. Conclusion there is a certain correlation between cruciate ligament tightness and meniscus injury, especially in young patients without knee osteoarthritis, the looser the ligament is. Meniscus injury is more likely to occur, but in elderly patients with knee joint arthritis, the degree of cruciate ligament tightness is not the main factor of meniscus injury.
