Mean joint angles for TE and PET-SI groups over the gait cycle for the A, B knee, C, D ankle, and E, F MTP. The horizontal dashed line in C and D indicates 90° where the ankle is at neutral dorsi/plantar-flexion. Red shaded areas indicate significant differences between baseline and 2 weeks post-surgery. Blue shaded areas indicate significant differences between baseline and 8 weeks post-surgery. Purple shaded areas are the overlap of red and blue shaded areas. a: p = 0.001; b: p = 0.002
