Posterior Tibial Tendon Dysfunction (PTTD)
Posterior tibial tendon dysfunction (PTTD) is a condition caused by changes in the tendon, impairing its ability to support the arch, which results in flattening of the foot. PTTD is often referred to as "adult acquired flatfoot" because it is the most common type of flatfoot developed during adulthood. PTTD is normally caused by overuse of the posterior tibial tendon, which is commonly found in those that participate in physical activities such as running, walking, hiking or climbing stairs. The symptoms of PTTD can include redness, swelling, pain, flattening of the arch and an inward rolling of the ankle. The symptoms can change as the condition progresses. There are many treatment options available for PTTD, including orthotics, physical therapy, medications, shoe modifications and immobilization. Occasionally, surgery is required.
