Posterior tibial tendon rupture: classification, modified surgical repair, and retrospective study

Posterior tibial tendon rupture is often misdiagnosed. The authors have presented a retrospective study of a new variation to the repair of this tendon. The anatomy, physiology, etiology, clinical manifestations, radiographic and magnetic resonance imaging, and historical methods are reviewed. A classification scheme based on location and appearance is discussed. A review of 17 cases was performed with results of 88% pain relief following the discussed procedure.
