Flat foot is quite a common problem of the foot, but most of the time simply having a lower arch or flatter foot is not necessarily a problem. What is a concern is if it is progressive and becomes painful, then it is called posterior tibial tendon dysfunction or adult acquired flatfoot. In such cases the arch of the foot becomes gradually lower and the heel rolls inwards. This is usually associated with pain in the arch of the foot and in the ankle area. Those with this also find walking is a lot is a lot and walking consumes a lot of effort leading to lots of fatigue.The reason for posterior tibial tendon dysfunction is not totally, however it is a problem where the posterior tibial tendon and muscle can not just do the job that it is designed for.
The principal role of the posterior tibial tendon is to hold up the arch of the foot and prevent the rearfoot rolling inwards. For reasons unknown the muscle and tendon complex can not just do their task any more, resulting in the progressive nature of this condition.The treatment of posterior tibial tendon dysfunction is almost urgent and ought to be dealt with as early as it possibly can. This is due to the problem is progressive and it will get to a stage where conservative methods don't work and surgery is the only option. As the surgical outcomes are in general satisfactory, they do include the fusion of some joints to prevent the condition getting worse, that comes with some long term limitations on gait as well as function, so is best avoided. To prevent the surgical treatment, treatment options ought to be started early. This will involve foot supports that are very supportive and position the foot back in the right direction. Exercises are also encouraged, but should never be used instead of foot orthotics, as they are crucial to stop this problem from progressing.
