Adult Flat Foot Overview 

By: Dr. Hiram Carasquillo

What are Flat Feet?

Progressive or acquired flat foot deformity may result from the functional loss of the Posterior Tibial Tendon. Do you have flat feet? This condition is very common, often painless, and can be caused by a multitude of different factors.

Flat feet are a common orthopedic condition commonly caused by genetics.

Most individuals that have flat feet do not present any signs or symptoms if they are not in pain. However, in some cases foot pain can be felt in the heel or arch area. Swelling near the ankle may occur as well. In addition, abnormal stresses on the knee and hip joints may result in pain in these joints as well. If you are experiencing pain in any of these body parts, you should consult a medical professional.

Flat Foot Risk Factors and Causes

  • Weak arches in the feet: These arches may be visible when the person is sitting, but when they stand the arches flatten on to the ground.
  • Genetics: Flat feet may be passed on from parents on to their children.
  • Functional loss of the posterior tibial tendon due to injury or damage.
  • Other medical conditions such as rheumatoid arthritis.
