Pain to the inside of the ankle and foot can be caused by posterior tibial tendinitis. This is frequently seen in patients with flat feet. The posterior tibial tendon helps to support the arch and maintain arch height. Over time, this tendon develops inflammation when there is increased stress to the arch.
Posterior tibial tendonitis worsens with time. Usually it only affects one foot. Pain frequently occurs with ambulation and there is pain when getting up from a seated position. Patients frequently notice increased pain when barefoot, standing, or walking for a prolonged period of time.
Posterior tibial tendinitis is commonly treated in the office with examination of your foot type including a gait exam. Dr. Stephen Moore and Dr. Efthymios Gkotsoulias will determine your foot type to help in resolving your pain. X-rays are frequently ordered to evaluate severity of flat foot. Treatment may include anti-inflammatory medication, bracing, arch supports, custom orthotics, or boot.
If left untreated, chronic inflammation causes stretching and thinning of the posterior tibial tendon. This can cause the arch to collapse. When the arch starts to fall, this is called adult acquired flat foot deformity. Patients will notice that one foot has a lower arch when standing. With time, arthritis can develop in a flat foot when the joints lack proper alignment.
