Fig 4.

(A) Arthroscopic photograph and drawing of right knee (in supine position), viewed from standard anterolateral portal. Two suture limbs are shown: one limb of the No. 5 Ethibond and the opposite limb of the Ultrabraid. The 2 limbs are retrieved through the polydioxanone suture loop and shuttled to the anterolateral tibial tunnel in a crossing-bridge pattern. (B) The remaining suture limbs are shuttled to the anteromedial tibial tunnel in the same manner. (C) Two limbs of the sutures (one each from the anteromedial and anterolateral tibial tunnels) are tied separately over a screw and post, thereby completing the suture-bridge fixation system. (D) Drawing of right knee in lateral view, illustrating transosseous suture-bridge fixation technique. The asterisks indicate the tibial spine avulsion fragment. (LFC, lateral femoral condyle; MFC, medial femoral condyle; T, tibia.)
