Fig. 3. In the operating field, a partial rupture of the inferior extensor retinaculum is observed approximately 5 cm upward from the ankle joint (A); however, the continuity is maintained as shown in (B, C). The tibialis anterior tendon is exposed, and there is a longitudinal tear proximal and distal around the ankle joint. The total length of the tear is approximately 13 cm, and the proximal tear was about 10 cm longer. The tibialis anterior tendon rupture is multiple and linear in the longitudinal direction, which extends to the proximal muscle-tendon junction. Multiple longitudinal tears of the tibialis anterior tendon are concentrated in the distal part from the ankle joint, and the proximal part showed less ruptures with only one or two strands.
