What is it?

Posterior tibial tendon dysfunction (PDDD), or tendinitis, refers to a condition that causes ankle and foot pain. The posterior tibial tendon connects the calf muscles to the bones in the inside of the foot. The tendon supports the arch of the foot. When the tendon is injured, it cannot support the foot arch. PDDD most commonly affects people who suffer from obesity, hypertension, diabetes, foot or ankle tissue injuries, joint disorders, prior surgery and steroid use.
