Traumatic rupture of the tibialis anterior tendon associated with chronic tibialis posterior dysfunction

Abstract Isolated rupture of the tibialis anterior and tibialis posterior tendon is uncommon with approximately 25 cases reported in the English literature. Rupture of the tibialis anterior in the presence of chronic tibialis posterior dysfunction has not been reported to date. We present a patient with a closed traumatic rupture of the tibialis anterior tendon which occurred on a background of a pre-existing tibialis posterior dysfunction which was being treated non-operatively and discuss the successful operative management that was performed to reconstruct both tendons.
