POSTERIOR TIBIAL TENDINOSIS / TIBIALIS POSTERIOR TENDINOSIS
Posterior Tibial Tendinosis (not to be confused with Posterior Tibial Tendinitis) 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 Tibial Tendinopathy will be found in that general area (often just below it).

The Tibialis Posterior Tendon takes an interesting pathway. The muscle itself attaches to the largest bone of the lower leg (the Tibia), and its tendon comes down on the inside part of the ankle. However, the tendon wraps itself around the back of the Medial Malleolous (the inside ankle bone) and heads downward underneath the foot where it attaches to the base of the middle toes.
