Posterior Tibial Tendon Dysfunction

Posterior tibial tendon dysfunction, also known as acquired adult flatfoot deformity, is a condition that results in a weakening of this tendon, rendering it unable to provide arch support. A repetitive injury that often occurs during walking, standing or climbing stairs, it is generally accompanied by pain and a limp.

Posterior tibial tendon dysfunction may be treated successfully with a combination of physical therapy to strengthen the tendons and muscles and use of an ankle brace to restrict mobility. In more severe cases, surgery may be required to repair the damaged tendons and realign the structure of the foot.
