Often times, when knee problems are evident, it is wise to look at the feet.

The biomechanically weak foot can not only have symptoms in the foot itself, but also the ankle, leg and knee. A problem in the foot can cause secondary troubles anywhere from the sacroiliac joint to the forefoot.

That’s the reason we have to have a thorough understanding of the biomechanics of the body from the back all the way down the entire leg to the foot. You can’t separate one factor from the other.

All sports present their own type of overuse syndrome. Distance runner’s problems include the knee, heel and Achilles tendon. The long-distance runner is subjected to shin splints and ankle troubles as well.

Sprinters, who run on the balls of their feet, develop bunions and tight posterior muscles. Basketball players have a high incidence of hammertoes. All athletes are subjected to recurrent lateral ankle sprains.

The orthopedic approach to overuse syndrome has been very successful. By the orthopedic approach, we mean the establishment of motions and positions which will cause maximum function of the foot and the entire skeletal system so that there will be a postural and structural balance.

In biomechanical balancing we attempt to cause the feet to function as close to their neutral position as possible.

Neutral position duplicates the joint positions assumed by a normal foot on standing and when running. Many of the problems leading to the overuse syndrome can be treated by biomechanical balancing.

In podiatric sports medicine, this is accomplished by functional sports orthotic. A functional sport orthotic or a functional orthotic, used for people on their feet for many hours during the day, is a device which controls motion and position of the foot and leg during locomotion. It is well tolerated and usually results in improved foot function with athletes and people who walk in the daily life to prevent injury.
