Foot Conditions A-Z
Posterior Tibial Tendinitis
Tendons are the strong bands of tissue that connect muscles to bones. Tendinitis is simply inflammation of a tendon, but it can create pain and tenderness near joints. In the feet, the posterior tibial tendon is among the most commonly affected. The posterior tibial tendon is one of the key supporting structures of the foot, helping it to function while walking. It attaches the calf muscles to the bones on the inside of the mid foot and runs down the leg and into the foot just inside the ankle bone.
Note that posterior tibial tendon dysfunction (PTTD) is a separate condition caused by inflammation or damage to the tendon that reduces its ability to support the arch, often resulting in flat feet.
