Traumatic dislocation of the tibialis posterior tendon: a new surgical procedure to obtain a strong reconstruction.

Traumatic dislocation of the tibialis posterior tendon (TPT) is an uncommon condition. The diagnosis is difficult and may be delayed, impairing the activity level. The authors present a case, wherein the diagnosis was clinical, supported by magnetic resonance imaging. Treatment was surgical; reconstruction of the retinaculum was performed with a medial slip of the Achilles tendon that was detached proximally and attached to the medial malleolus. A full functional recovery to a highly competitive activity was obtained after 12 weeks.
