Facts about Adult Acquired Flatfoot


At Paul S. DeMarco, DPM, many of our adult patients have flat feet and are not experiencing any discomfort. However, this condition requires careful monitoring as you age. Adult acquired flatfoot, also known as posterior tibial tendon dysfunction (PTTD) can become a painful and debilitating deformity. Here are some facts you should know about this disorder:

  • The mean age of people affected with adult acquired flatfoot is 60 years old. This is because the posterior tibial tendon can stretch with age, as can the ligaments and muscles that support the arch of the foot.
  • More women than men have adult acquired flatfoot.
  • This disorder usually only affects one foot but can affect both.
  • Adult acquired flatfoot is a progressive disorder that will not improve without treatment. Left untreated, the flatfoot can become a rigid and permanent deformity.
  • In the early stages of adult acquired flatfoot, symptoms include swelling, pain and inflammation on the inside of the ankle and foot. As the disorder progresses, the pain may shift to the outside of the foot, the toes and foot turn outward and the ankle begins to roll inward.
  • People who are obese or have diabetes or hypertension have an increased risk for adult acquired flatfoot.
  • Adult acquired flatfoot is best treated in its early stages. Treatment may include anti-inflammatory medications, custom orthotics, physical therapy or surgery.

If you have flat feet, with or without pain and discomfort, you should have our board certified podiatrist, Dr. Paul S. DeMarco examine them. The foot doctor will want information about your symptoms and how they’ve changed over time. Part of the evaluation of your feet will include strength testing of foot muscles and observing your feet as you walk. Remember that the earlier adult acquired flatfoot is diagnosed and treated, the better the results. Contact our office for an appointment today by calling: (609) 927-4894.
