October 26, 2012Posterior tibial tendon dysfunction or adult acquired flatfoot is a very disabling condition. It is due to the posterior tibial muscle and tendon complex failing to adequately di its job of support the arch of the foot and supinating or inverting the foot. As a consequence of this there is a progressive flattening of the arch of the foot with rolling medially or inwards at the ankle joint. There is progressive pain associated with this. Posterior tibial tendon dysfunction is also very fatiguing as a lot of energy is expended to walk around if you have it. It is important this posterior tibial tendon dysfunction is diagnosed early to halt the progression. In the early stages foot orthotics and exercises are extremely important. If this does not halt the progression or the diagnosis is late, then surgery is usually the only option.
