Fig. 5.

Representative two-dimensional contour plot of contact pressure on the talar dome with the hindfoot in the inverted and axially loaded position at 20° of plantar flexion. The gray line in each image indicates the path of the center of pressure (CP) from the axially loaded position with no inversion moment to the axially loaded position with inversion moment. The gray and white box in each image indicates the location of the center of pressure under both axial and inversion loads. Ant = anterior, Med = medial, I = intact, D = deficient anterior talofibular and calcaneofibular ligaments, B = Broström, BG = Broström-Gould, and G = graft.
