BTF system. (A) The BTF system consists of two primary components: an SB and a PS. First, the SB is hammered into the distal aperture of the tibial tunnel. The PS is then inserted through the central hole of the SB into the bone plug positioned within the tibial tunnel. As the PS advances through the longitudinal hole of the bone plug, it connects the bone plug to the SB and pulls it distally. This distal traction both tensions and secures the graft simultaneously. (B) A postoperative radiograph shows the correct positioning of the BTF system. (C) A postoperative computed tomography scan confirms proper alignment of the SB and PS within the tibial tunnel. This image is published with the patient’s consent. BTF, Bone Plug Tensioning and Fixation; PS, pullout screw; SB, spike button.
