Adult Acquired flatfoot

Adult acquired flatfoot is a condition affecting the feet and ankles that causes the foot’s arch to collapse. This can be a painful condition that happens gradually and causes the bones of the foot to shift out of alignment.


There are a number of situations that can cause flatfoot in adults, but the most common is a problem with the posterior tibial tendon. This tendon is located from the calf to the inner side of the foot, and supports the arch of the foot as you walk. If this tendon is injured or swollen, the arch can collapse. Other factors that can lead to this condition include rheumatoid arthritis, diabetes, obesity, and sports injuries.


Symptoms of adult acquired flatfoot vary depending on what is causing the condition. The most common symptoms of flatfoot are pain, swelling, and redness at the foot and ankle. Walking or standing for long periods may be difficult. In some cases, the bone can shift out of alignment, turn outward, and roll inward. Bony bumps and ulcers in the feet may also occur.


Physicians will diagnose adult acquired flatfoot by examining the foot and assessing symptoms. Flatfoot is usually evident when the full weight of the body is placed on the feet when standing. Patients may also be asked to stand on tip-toes or heels to see if an arch forms.


Treatments vary depending on what is causing adult acquired flatfoot. Effective treatments include foot tapings, braces, shoe inserts, anti-inflammatory medications, and choosing different shoes. Weight loss may also help for those with symptoms impacted by obesity. If conservative treatments are not effective, surgery could be required.
