Anterior and posterior fibers of the TA. (a) Lateral view of the right leg. (b) The central aponeurosis was exposed, and parts of the posterior fibers were flipped by forceps. The anterior and posterior fibers were defined by their positional relationship with the central aponeurosis. (c) The TA was removed from the tibia. The anterior and posterior fibers were reflected anteriorly and posteriorly to the central aponeurosis, respectively. af, anterior fiber; FH, fibular head; pf, posterior fiber; TA, tibialis anterior; TT, tibial tuberosity; asterisk, central aponeurosis
