Posterior Tibial Tendon Dysfunction (PTTD)
Posterior Tibial Tendon Dysfunction (PTTD) or known as Adult Acquired Flat Foot is a progressive flat foot condition that causes pain in the ankles or the arch. It is due to inflammation, tear, or degeneration of the Posterior Tibialis Tendon. This tendon runs from the back of our lower leg and attaches to the navicular bone, and it is responsible for supporting and raising our arch when we stand or walk.
Patients with PTTD will experience pain and swelling along the inner side of the ankle or the arch region during standing or walking. They will also have trouble standing on their toes or balancing on one foot. The condition can progress to developing severe flat foot deformity if left untreated.
