Posterior Tibial Tendon Dysfunction, or PTTD, is referred to by various names including posterior tibial tendon syndrome, posterior tibial insufficiency, and adult acquired flatfoot. PTTD is a dysfunction of the tibialis posterior muscles which causes a flat foot or fallen arch. Often, strengthening exercises are prescribed to regain proper function of this muscle.
