Posterior Tibial Tendon Dysfunction (PTTD): Causes, Symptoms, and Treatment Options
What is Posterior Tibial Tendon Dysfunction (PTTD)?
Posterior tibial tendon dysfunction (PTTD) is a condition in which the posterior tibial tendon, which helps support the arch of the foot, becomes inflamed or torn. This condition can lead to flatfoot deformity and pain on the inside of the ankle and foot.
