Fig 5 — Intermediate stage of tunnel filling. (A) The central section of the tunnels is filled with a combination of demineralized bone matrix (DBM) and corticocancellous spongy chips (I). Once the tunnel has a “bone roof” (II), DBM is inserted from proximal to distal using a cannula and embolus (III). It is advisable to make small pauses to fill all the holes and compact the paste. Bone chips are used again to close the articular end of the tunnel. The cannula is inserted through the anteromedial portal (IV). (B) An intraoperative arthroscopic image taken from the anterolateral portal shows the introduction of DBM (I) through a cannula (II) introduced through the anteromedial portal in the previously debrided femoral tunnel.
