phosphorusPain in the medial (inner) part of the ankle is often caused by posterior tibial tendon dysfunction (PTTD), also known as posterior tibial tendon syndrome or posterior tibial syndrome, and can be very difficult to treat.

The tibialis posterior is an especially important muscle for runners because it is used to plantarflex the ankle (bring the ankle/toes down) and varus (roll the ankle inward). More importantly, it acts to support the arch of the foot. Injuries to this muscle are common among runners and those who play sports that involve high impact on the feet, such as basketball. It can be associated with falls, or it can usually develop over time, depending on your risk factors and the stress on your feet. (See 9 Tips for Self-Treatment of Posterior Tibialis Pain.)

In this video, I demonstrate a taping technique that provides support to the arch and sole of the foot for people with PTTD. (I recommend KT tape.)

PTTD most often begins with an overuse injury. While the condition is more common among runners and those who participate in high-intensity sports, the condition can affect anyone. If left untreated, the end result is often a collapsed arch, which can lead to acquired flat feet in adults. Self-treatment is possible if the condition is caught early. Once the arch has dropped, surgery is likely to be required.
