Rupture of the tibialis anterior tendon.

Rupture of the tibialis anterior tendon is rare. There is usually a delay in diagnosis, probably because it is an uncommon entity. Diagnosis is easy however, and recovery with surgical treatment is satisfactory if repair is performed within the first three months following the initial trauma. After this period of time, an operation is less likely to be effective. We report a case with successful outcome following surgical repair of a ruptured tibialis anterior tendon.
