Figure 1: Magnetic resonance imaging (MRI) of a left knee of a 21-years old male patient one year after ACL reconstruction with an autologous quadriceps tendon grafts. A) Coronal T2-weighted coronal image with the arrow indicating the fibrous interface between the soft tissue graft and the bone tunnel. B) T1-weighted coronal cut with a homogenous intra-tunnel portion of the graft (arrow). C) T1-weighted sagittal image. At the distal part of the tibial bone tunnel the interference screw is visible. The arrow proximal to the interference screw highlights the fibrous interface in the anterior part of the bone tunnel.
