Posterior tibial tendon dysfunction is a condition resulting from overuse or injury to the tendon. The posterior tibial tendon connects the calf muscle in your lower leg to the inner part of your foot. When the posterior tibial tendon becomes inflamed or torn, it no longer can support the arch of your foot which collapses as a result. When there is a more significant injury to the posterior tibial tendon than can be simply repaired, a tendon transfer is done to reinforce the torn tendon. Common tendons used are flexor digitorum longus or other tendonds that belong to another area of the foot.
