(A) Transverse section of tibia showing 4 tunnels in relation to ACL fragment. The technique provides 4-point fixation. (B) Sagittal section of knee joint showing position of posterior and anterior tunnels. (C) All the sutures are withdrawn at the AM part of the tibia and are ready to be tied. Approximately 15 mm of bony bridge is preserved among the 4 tibial tunnels. First, the sutures of the PL bundle are tied at 50° of knee flexion; then, the sutures of the AM bundle are tied at 20° of knee flexion.
