The Correlation Of The Width Of The Intercondylar Notch And The Transverse Diameter Of The Anterior Cruciate Ligament In The Tibial Terminal

Objective:The purpose of this study is to identify a possible correlation between the femoral intercondylar notch width and the ACL transverse diameter in the tibial terminal of the different gender of ACL rupture group and ACL intact group.Methods:This study included 37 patients undergoing arthroscopic examination which contains patients with ACL rupture and patients with intact ACL.Intraoperative measurements were taken using an arthroscopic ruler at the base,middle and the top of the notch.The transverse diameter of the ACL in the tibial terminal were measured.The differences between the two groups and gender of the notch width and ACL transverse diameter were determined.The correlation between the notch width and ACL transverse diameter in the tibial terminal of each group were calculated.Results:There were no significant differences between the ACL rupture group and the ACL intact group or between men and women of notch width and ACL transverse diameter in the tibial terminal.Significant positive correlations were found between the notch width and ACL transverse diameter in the tibial terminal of the man in the ACL intact group,but not of the man in the ACL rupture group or women in the ACL intact group.Conclusion:The significant correlation between the notch width and ACL transverse diameter in the tibial terminal of the man in the ACL intact group,but not the man in the ACL rupture group or women in the ACL intact group indicates that it is an ACL injury risk factor with an extremely thick or thin ACL compare to the intercondylar notch width.
