Y configuration graft preparation. (A) The harvested peroneus longus tendon is cleaned and laid out on a graft preparation board. The minimal length required for this technique is 250 mm. The graft is marked at 25 mm from the distal tip (mark 1), then at 45 mm from the previous mark (mark 2), and finally at 25 mm from the second mark (mark 3). (B) The segment between the distal end of the graft and mark 1 is whipstitched with No. 2 FiberWire, and the loop of the TightRope RT is placed at mark 3. (C) A length of 25 mm of looped graft around the TightRope RT loop is sutured to prevent slippage from the loop. (D) The final prepared Y graft construct has a distal 25 mm for insertion into the femur popliteus socket, a 45-mm-long segment for the popliteus tendon (PT), a looped 25-mm segment for the tibial tunnel insertion of the popliteus and popliteofibular ligament (PFL), and a longer graft segment to be used for the popliteofibular and fibular collateral ligament reconstruction.
