Flatfeet
Overview and Facts about Flatfeet
Flatfeet is an orthopaedic condition in which the arches of the feet collapse, allowing the entire sole of the foot to touch the ground. Flatfeet is also known as pes planus or fallen arches. The condition is common, with more than three million cases reported each year in the United States.
This condition doesn’t always cause noticeable symptoms. However, some people with flatfeet report chronic foot pain. Flatfeet can also affect the alignment of your legs and could result in pain in the knees or ankles.
Signs and Symptoms of Flatfeet
Flatfeet may cause some of the following symptoms:
- Foot pain
- Back pain
- Leg pain
- Swollen feet
If you have flatfeet, the soles of your feet may feel tender. Your feet might tire easily, and your feet or ankles might swell from overuse.
Because fallen arches can affect your gait, you might also develop pain in your legs or back. Some movements, such as standing on your toes, could be difficult or painful.
Causes and Risk Factors of Flatfeet
Flatfeet is often caused by damaged or weakened tendons in the heel and arch of the foot. In other cases, the condition may be due to a medical issue that's present from birth. Medical conditions such as rheumatoid arthritis can also cause flatfeet.
Other risk factors for flatfeet include:
- Obesity
- Pregnancy
- Diabetes
- Nerve disorders
- Increased age
Tests and Diagnosis of Flatfeet
If your doctor suspects that you have flatfeet, they will perform a physical exam. Your doctor might ask you to perform routine tasks such as walking across a room or standing on your toes.
During the exam, your doctor will examine your leg and foot muscles to check their strength. Your doctor might also look at your shoes to check the wear pattern.
Your medical history can also be helpful for diagnosing flatfeet. Your doctor may ask several questions about past illness or injuries that increase your risk of flatfeet.
A physical exam is often enough to diagnose flatfeet. In some cases, your doctor might order imaging tests, such as an MRI or X-ray, to view the bones in your feet.
