Abstract
Dislocation of the posterior tibial tendon (PTT) is a rare pathological process that occurs most often as a result of acute trauma. The injury involves forced dorsiflexion and eversion of the foot against a contracted posterior tibialis. Diagnosis of the injury is often difficult secondary to the rarity of the injury and its similarity with other benign injuries of the medial ankle. Routine diagnostic imaging often does not reveal the injury, and advanced imaging with magnetic resonance imaging or ultrasound to confirm the diagnosis is often required. The injury can be a result of an abnormal retromalleolar groove or a tear of the flexor retinaculum. Because nonoperative treatment frequently results in poor outcomes with continuing pain and progressive flat foot, operative treatment with repair of the flexor retinaculum with correction of the retromalleolar groove is the most described intervention. We report an acute case of PTT dislocation in a collegiate gymnast during competition and offer our technique for surgical correction in the setting of a partially torn, attenuated flexor retinaculum with plate buttressing of the PTT into its native uncorrected groove.
