Posterior tibial tendon dysfunction is one of the most common problems of the foot and ankle. It occurs when the posterior tibial tendon becomes inflamed or torn.
As a result, the tendon does not stabilize and support the arch, resulting in flatfoot.
Posterior Tibial Tendonitis commonly occurs during overuse with sports, but also can be attributed to walking incorrectly on the inside of the foot, falls, arthritis, or with weight gain.
The posterior tibial tendon is one of the most important tendons of the leg. The posterior tibial tendon attaches the calf muscle to the bones on the inside of the foot. The main function of the tendon is to hold up the arch and support the foot when walking.
With post-tibial Tendonitis, pain will be more severe upon weight bearing activity, especially while walking or running. This can lead to heel pain, plantar fasciitis, heel spurs, pain and swelling on the inside or outer side of the ankle, fallen arches/flat foot, weakness, inability to stand on the toes, and/or tenderness in the mid foot, especially when under stress during activity.
Most patients can be treated using orthotics. The custom orthotic allows the doctor to better control the position the foot.
A custom orthotic is required in patients who have moderate to severe changes in the shape of the foot.
