^*D–S represents the direction of deep to shallow; H–L represents the direction of high to low; M-L represents the direction of medial to lateral; A-P represents the direction of anterior to posterior
^†the difference between the position of the bone tunnel in traditional and robotic surgery was significant (p < 0.05)
^‡the difference between the position of the bone tunnel in traditional surgery and the position of the anatomical insertion site position of the ACL was significant (p < 0.05)
