Hemodynamics of the bone tunnel wall and grafted tendon after ACL reconstruction are shown, including the results from this study and previous literature. Although blood flow reached the bone tunnel wall at 2 months after reconstruction from the middle genicular artery, blood flow resumes especially from the posterior bone tunnel wall on the femur side, which is closer to the artery. Blood flow was restarted within the tendon parenchyma at 3 months. On the tibial side, there was no significant difference in the early postoperative period, but finally blood flow was more abundant in the anterior bone tunnel wall closer to the inferior genicular artery, which is the feeding vessel of the tibial bone tunnel wall
