What is posterior tibial tendon dysfunction?

James P. Ioli, DPM
Podiatric Medicine
The posterior tibial tendon is a large tendon that runs along the inner side of your lower leg and ankle. It attaches to the inner side of your arch and is one of the arch's main support structures. In some people, this tendon can degenerate, stretch, or tear, resulting in posterior tibial tendon dysfunction. This condition may arise from an injury, but it most commonly develops because of simple wear and tear. It can be compared to the loss of elasticity that occurs in a rubber band that has been stretched too often and too long, so that it won't bounce back after it's stretched. Similarly, your posterior tibial tendon can suffer tiny tears and degradation over time, compromising its elasticity.
