PURPOSE: The primary purpose of the current study is to identify a possible correlation between the femoral intercondylar notch size and the ACL insertion site size. The secondary purpose is to determine if there is a difference between male and female notch widths and insertion site sizes. METHODS: For this study, 82 patients (41 men and 41 women) with an average age of 24.1 ± 10.0 years (range 13-58 years) undergoing anterior cruciate ligament (ACL) reconstruction were included. Arthroscopic measurements were taken at the base, middle, and top of the notch. Additionally, the notch height was measured at the highest point. The insertion sites of the ACL were identified, marked using electrocautery, and measured. The correlation between notch width and ACL insertion site size was calculated. In addition, differences between men and women with regard to the notch width and ACL insertion site size were determined. RESULTS: Significant positive correlations were found between the notch widths and ACL insertion site measurements and ranged from 0.222 to 0.379 (P < 0.05). There were significant differences between men and women with regard to notch and insertion site size. CONCLUSION: The results of this study show that there is a significant, but weak correlation between the notch width and the ACL insertion site size. Women had a smaller notch and a smaller insertion site than men. This knowledge could influence pre-operative decision-making with regard to graft choice, single- or double-bundle surgery, and graft size.
