In this video, we will discuss tibialis posterior tendonitis. Originating deep in the calf, the tibialis posterior travels around the inside of the ankle attaching to the side and bottom of the foot. The tibialis posterior acts to control how much and how fast the inside arch is allowed to collapse while standing, walking, or participating in activity. When the tibialis posterior is overused, the tendons can become irritated and inflamed, causing pain behind the ankle bone and into the foot.
Conservative treatments include activity modification, physiotherapy, and pedorthic care such as appropriate footwear and custom foot orthotics. Custom foot orthotics support the arch, control excess motion, and reduce the demand on the tibialis posterior tendon, thus reducing pain.
