The graft tendon-bone tunnel interfacial healing was measured as the bone tunnel diameter (T1; A) and peri-tunnel edema (T2; B) at the level of entry of femoral (green) and tibial (blue) bone tunnels. The T2 signal of femoral bone marrow in the middle third of femoral shaft (red) was set as the reference to normalise the individual peri-tunnel edema change
