What is posterior tibialis tendon dysfunction?
Posterior tibialis tendon dysfunction (PTTD) is a muscle tendon issue usually affecting one foot involving inflammation and degeneration. If left untreated, the tendon can rupture and require surgery. PTTD can occur acutely from specific tendon injury but tends to develop over time and is sometimes called an ‘overuse’ injury or tendon ‘insufficiency’. PTTD is a major cause of developing adult acquired flat foot deformity showing a change in foot shape as the arch flattens over time resulting in bone deformity and osteoarthritis.
