Abstract:

Objective To explore the correlation between tightness of cruciate ligaments and injury of patellofemoral joint surfaces, and provide new guidances for the prevention,diagnosis and cure for the diseases of patellofemoral articular surfaces by analyzing the influence of anatomical differences in the length of individual's cruciate ligaments on the injury of patellofemoral articular surfaces. Methods A(length of anterior cruciate ligament), B(length of posterior cruciate ligament), La(attachment distance of anterior cruciate ligament)and Lb(attachment distance of posterior cruciate ligament)were measured on the sagittal plane from MRI data of 110 knees from 100 patients in Zhujiang Hospital of Southern Medical University between October 2016 to December 2017, and then figured out the value of M which represented tightness of cruciate ligaments; the degree of injury of patellofemoral joint surfaces which were graded 0, I, II, III and IV were evaluated from sagittal and coronal plane, and were classified as 5 groups respectively. Data were analyzed with the methods of One-Way ANOVA and Spearman correlation analysis to explore the correlation between tightness of cruciate ligaments and injury of patellofemoral joint surfaces by SPSS20.0 statistical software. Results The M values which were obtained from One-Way ANOVA analysis of variance showed a significant difference between any two groups (P<0.05). Spearman correlation analysis suggested a positive correlation between M value and injury of patellofemoral joint surfaces. Conclusion The tightness of the cruciate ligaments has positive correlation with the injury of patellofemoral joint surfaces. The greater the M value is, the more severe the injury of patellofemoral joint surface is.
