Tendon disorders of the foot and ankle, part 3: the posterior tibial tendon.
This article provides a review of posterior tibial tendon pathology and the authors' preferred management. The tibialis posterior musculotendinous unit is the most powerful inverter of the foot and an important dynamic stabilizer of the arch. In the stance phase of the gait cycle, it serves as an initiator of both ankle plantar flexion and subtalar inversion. This creates a rigid midfoot by stabilizing the transverse tarsal joint, and allows for increased power generation by the gastrocsoleus complex through toe-off. Injuries to the posterior tibialis tendon include traumatic laceration and dislocation, as well as tenosynovitis and tendinopathy, which can lead to attenuation and rupture. If these injuries are not addressed, significant clinical deformity and disability can result.
