What Is PTTD?

PTTD occurs when the posterior tibial tendon, which supports the arch of the foot, becomes inflamed or torn. This causes the arch to collapse over time, resulting in flatfoot, pain, and progressive instability.

It’s often caused by overuse, but factors like obesity, diabetes, or previous ankle injuries can also contribute.

Common Symptoms of PTTD:

  • Pain and swelling on the inside of the ankle

  • Flattening of the arch (especially on one foot)

  • Foot turning outward while walking

  • Difficulty standing on tiptoes

  • Increased fatigue in the foot and ankle after activity

What Happens If It’s Not Treated?

PTTD is a progressive condition. Left untreated, it can lead to severe flattening of the foot, arthritis, and permanent deformity that may require reconstructive surgery.
