Anterior dislocation of posterior tibial tendon: a case report

Abstract

In contrast to the posterior tibial tendon injuries, its dislocations are considered extremely rare. Consequently, the diagnosis of this condition is not usually established, and such fact delays the beginning of the treatment. We present a rare case, which may have an origin that is not related to trauma. A 29-year-old, male, patient appeared at our office stating that pain in his right ankle did not improve with treatments that were used in the past 12 months. He denied local trauma or sprain of the ankle. He reported increased volume of the medial malleolus and pain on palpation. He also referred not being able to remain supported on the tip of the affected foot, and after that start playing football with friends he was forced to interrupt the activity. He underwent surgical reduction followed by immobilization on short leg cast for 30 days. After removal of the immobilization, the patient underwent physical therapy for 30 days. After the physical therapy, he was able to support full weight on his foot and neutral and full plantar flexion (tip toes), without pain. Patient returned to recreational sport (soccer) with no complaints, 90 days after the end of the physical therapy.
