Dislocation of the posterior tibial tendon: a literature review and presentation of two cases.

Dislocation of the posterior tibial tendon has rarely been reported in the English literature. The most common mechanism is a traumatic injury. We present two patients with a traumatic dislocation. One patient was delayed in presentation to the treating physician by seven months. The second patient presented within one week. Both underwent surgical stabilization with repair of the torn retinaculum and deepening of the groove posterior to the medial malleolus. They have both returned to their pre-injury level of activity without any recurrence of dislocation.
