Posterior Tibal Tendonitis

Posterior tibial tendon dysfunction is a problem that occurs in one of the tendons on the inner side of the ankle. Posterior tibial tendon problems usually occur just underneath the prominence of the inner side of the ankle, called the medial malleolus. The medial malleolus is the end of the shin bone (the tibia) and the posterior tibial tendon wraps just underneath the medial malleolus.
