a Reconstruction and superimposition of the three-dimensional (3D) models of the tibia and the three tibial tunnels at 3 weeks and 1 year after surgery. The red and the green 3D models indicate the two anterior tunnels at 3 weeks and 1 year after surgery, respectively. The blue and the yellow 3D models indicate the posterior tunnel at 3 weeks and 1 year after surgery, respectively. b Measurement of the cross-sectional areas (CSAs) of the tibial tunnels at 3 weeks and 1 year after surgery. The measurement was performed by cutting the 3D models of the two anterior tunnels (left) and the posterior tunnel (right), along the planes perpendicular to the tunnel axes (black arrow head), at the aperture and 5 and 10 mm distal from the aperture. The bottom right cube has a length of 20 mm on each side. M: medial, L: lateral, A: anterior, P: posterior
