A fallen arch (also known as Adult Acquired Flatfoot or posterior tibial tendon dysfunction (PTTD)), is a progressive condition that involves weakening of a tendon and ligaments that support the inside arch. You will begin to notice arch pain and collapse of the arch with an outward shift of the forefoot/heel and inward shift of the ankle. Orthotics and physical therapy can be helpful in the early stages, but in later stages a custom brace or surgery is required.
Below is an example of a patient that had severe arch collapse and arthritis as a result of a weak posterior tibial tendon. After reconstructive surgery, the patient is greatly improved. To learn more about surgery, visit our website page (Adult Flatfoot Reconstruction).
