An adult acquired “flat” foot is more than a cosmetic issue.
The foot is the foundation to the body and a misaligned foot will lead to misaligned to the rest of the body.
Ankle bone instability is something that is seen in childhood. Unfortunately, most parents and children are told that it is nothing to be concerned about and that the child will just outgrow this condition. This is not based on any science. Rather, most physicians are focused on the normal “fat” that can be found in the inner arch in babies, and as the baby matures, that fat disappears. A displaced ankle has never been proven to fix itself. Let's talk about the posterior tibial tendon; it's the strongest tendon that supports the inner arch of the foot. It is responsible to lift the inner arch during the walking cycle. When the ankle bone displaces on the heel bone, this places an increased strain on the tendon. The posterior tibial tendon is over-stretched more than 100 million times by the age of 60.
Eventually, these excessive forces acting on the tendon will take their toll and the tendon looses it’s strength and becomes diseased painful.
There are 4 stages or grades of chronic tendon destruction. Unfortunately, the tendon dysfunction will continue to get worse and most treatments are only aimed at temporary relief, rather than eliminating the excessive strain.
