Ipsilateral peroneus brevis tendon grafting in a complicated case of traumatic rupture of tibialis anterior tendon.

Ruptures of tibialis anterior tendon can be caused by open, closed, direct, or indirect trauma, as well as spontaneously. Sixty-three cases of tibialis anterior tendon ruptures have been reported in the international literature. The treatment of choice is the surgical end-to-end or side-to-side anastomosis after previous Z-lengthening. The case of a 28-year-old world-class female triathlete who sustained an open laceration of the tibialis anterior tendon from the bicycle chain guard is reported. The primarily applied tendon suture became infected and a wound revision with wide resection of the tendon stumps was necessary. This lead to an extensive defect of the tendon combined with a deep-seated keloidal scar reaction of the skin. The surgical closure was performed using free ipsilateral peroneus brevis tendon grafting. Four months after the operation the patient was completely rehabilitated. Eight months later she became the second European triathlon champion.
