causes of posterior tibial tendon dysfunction
Posterior Tibial Tendon Dysfunction (PTTD) The posterior tibial tendon serves as one of the major supporting structures of the foot, helping it to function while walking. Posterior tibial tendon dysfunction (PTTD) is a condition caused by changes in the tendon, impairing its ability to support the arch. This results in flattening of the foot. PTTD is often called adult acquired flatfoot because it is the most common type of flatfoot developed during adulthood.
Causes and Symptoms. Posterior tibial tendon overuse is one of the most common causes of PTTD. PTTD-related symptoms usually develop following activities such as stair climbing, hiking, walking, and running. PTTD may also be caused by a tendon abnormality.
