Fig 1 (A, B) Suture of the graft (star) to the loop of the TightRope (arrow) device with the help of a nitinol wire (triangle). (B, C) The graft (star) is looped around another TightRope double- (B) and quadruple-bundle (C) graft setting in the graft preparation station. (D, E) The other end of the quadruple graft (arrow) is sutured to the TightRope with the aid of a nitinol wire (triangle), setting a final quadruple graft (E). (F) Side-to-side suture is started with continuous suturing (arrow) trying to conceal the former knots on the graft extremities. (G, H) Final aspect of the graft after completion of the suture.

Fig 2 The cylinder (h1) represents a bone tunnel with a 12-mm-length and 7.5-mm-diameter bone socket and a total area of contact of 2.82 cm2. If a suture wire wrapping the graft end occupies 2 mm of the graft, then a reduction of 16% is expected of the tendon-bone interface contact area. The area corresponding to the occupied bone tunnel is represented in the figure by the smaller cylinder (h2), resulting in a total contact area of 0.47 cm2.
