POSTERIOR TIBIAL TENDON

POSTERIOR TIBIAL TENDON INJURY

 

The job of the Posterior Tibial Tendon is that it helps to hold up the arch of the foot. A foot has an arch because it is built to flex a small amount and to dull the impact we put on our feet when walking and running. So - you can imagine how much force this one tendon needs to use to prevent the arch from collapsing completely every time we step down. There are two types of injuries that occur to the posterior tibial tendon - acute tears and chronic overuse injury.
