Drill the fibular bone tunnel under arthroscopic visualization. The guide wire was introduced at the midpoint of the ATFL fibular foot print area. The safe distance of the guide wire between the articular surface and the lateral wall was confirmed by the probe a, b, c. A 4.5 mm cannulated drill was introduced via the guide wire to create a full-thickness tunnel in the fibula while the length of the tunnel was measured d. A cannulated drill with a diameter of 6.0 mm was then introduced via the guide wire to deepen the tunnel to a depth of 20 mm e. Arthroscopic view of the fibular bone tunnel f
