Abstract:

Objective This study was aimed to explore the correlation between tightness of cruciate ligaments and meniscus injuries anatomically.  Methods 260 knee-joint MRI were collected from Southern Medical University, Zhujiang hospital during January 2014 to December 2016. Then, the critical data according to MRI containing a[length of anterior cruciate ligament(ACL)], p [length of posterior cruciate ligament(PCL)], la (attachment distance of ACL) and lp (attachment distance of PCL)were measured to figure out the tightness coefficient R=(a+p)/(la+lp). t-Test and spearman correlation analysis were used to study these samples. Results t-Test presented significant difference between patients with and without meniscus injuries (P<0.05). Spearman correlation analysis showed the relatively strong correlation between R and meniscus injuries in non-osteoarthritis patients (rs=0.620) and weak correlation in osteoarthritis patients (rs=0.313).    Conclusion    The tightness of cruciate ligaments hasevident impact on the suffering of meniscus injury especially for youth without osteoarthritis. Nevertheless, it is probably not a major determinant resulting in meniscus injury for the elderly with osteoarthritis.
