Posterior Tib Tendinosis is a TENDINOPATHY of the Posterior Tibial Tendon. As is the case in most foot / ankle tendinopathies, it is found in athletes (runners), people who wear cruddy shoes, people who spend too much time on concrete, people who are overweight, or those who have very high or low arches (more commonly in very fallen arches).
The posterior tibial tendon is found on the inside of the foot, near the medial malleolus (the bony knob on the inside of the ankle), and the pain from Posterior Tib Tendinopathy will be found in that general area (often just below it and slightly to the front).
For a great picture, see the bottom pic on our ANKLE TENDINOSIS PAGE.
As is the case with most of the Posterior Tib Tendinopathy that I treat, one of the first things to do is get the patient in an orthotic. We offer good generic orthotics for under 50 bucks. However, for more severe cases of fallen arches, you will need a custom orthotic. The only company I recommend is Shawn Eno’s Xtreme Footwerks in Idaho Springs, Colorado.
