What is posterior tibial tendon dysfunction (PTTD)?

Posterior tibial tendon dysfunction (PTTD) is a condition that affects your foot and ankle. It happens when the posterior tibial tendon, a strong cord-like structure that runs along the inside of your ankle, becomes weak or inflamed.

Think of this tendon like a rope that helps support your foot arch and allows you to turn your foot inward. When this “rope” weakens, it can make it hard to walk and even cause pain.

Here are some common signs of PTTD:

Pain along the inside of your foot and ankle, especially when standing or walking
Swelling in the area
Flattening of the foot arch
Your foot turning outward when you walk

If you’re experiencing these symptoms, don’t worry! There are ways to manage PTTD and relieve your pain. It’s important to see a doctor or podiatrist to get a proper diagnosis and discuss treatment options.
