title: Spontaneous rupture of the posterior tibial tendon secondary to chronic nonspecific tenosynovitis.
abstract: Presented is a case history of complete rupture of the posterior tibial tendon and its subsequent surgical repair. Treatment included tendon repair followed by physical therapy and orthotic devices. Nine months after repair the patient was experiencing considerably reduced symptomatology but demonstrated significant posterior tibial muscle weakness and moderate subtalar joint pronation with forefoot abduction, with the deformity appearing to progress. This may indicate the need for additional surgical procedures to halt progression and lessen the chance of persistent pronation deformity.
