Posterior Tibial Tendon Dysfunction
Posterior tibial tendon dysfunction(PTTD), also known as posterior tibial tendonitis, is one of common conditions of the ankles and feet. PTTD is caused by inflammation or tearing of the posterior tibial tendon, which is one of the major supporting structures of the foot. As a result, the tendon is not able to support the arch of the foot. This causes flatfoot – the foot is fallen and the foot points outwards.
