During initial contact or heel strike, the ankle rolls inward, causing excessive pronation or flattening of the foot. This action forces the big toe (instead of the ball of foot and all toes) to do
all the work to push off the ground. When the ankle overpronates, this causes the tibia (shin bone) to rotate and the femur (thigh bone) to adduct (move toward the mid-line of the body), causing
internal rotation or knee valgus (knock-kneed).
Excess stress on the inner surface of the foot can cause injury and pain in the foot and ankle. Repeated rotational forces through the shin, knee, thigh and pelvis also place additional strain on the
muscles, tendons and ligaments of the lower leg.
Overpronation causes alterations in proper muscle recruitment patterns leading to tightness in the outside of the ankle (lateral gastrocnemius, soleus, and peroneals). This tightness can lead to
weakness in the opposing muscles such as the medial gastrocnemius, anterior tibialis, and posterior tibialis. If these muscles are weak, they will not be able to keep the knee in proper alignment,
causing the valgus position. All this tightness and weakness can cause pain within the ankle, calf, and knee region. And it can send imbalance and pain all the way up to the upper back, if deep core
strength is lacking and can't hold the pelvis in neutral.
At some point you may find the pain to much or become frustrated. So what are you options? Chances are your overpronation has led to some type of injury if there's pain. Your best bet is to consult
with someone who knows feet. Start with your pediatrist, chiropodist or chiropractor. They'll be able to diagnose and treat the injury and give you more specific direction to better support your
feet. One common intervention is a custom foot orthotic. Giving greater structural support than a typical shoe these shoe inserts can dramatically reduce overpronation.
Non Surgical Treatment
Overpronation is a term used to describe excessive flattening of the plantar arch. Pronation is a normal part of our gait (the way we walk), and it comprises three movements: dorsiflexion, eversion,
and abduction. Dorsiflexion is the upward movement of the foot, eversion describes the foot rolling in, and abduction is ?out toeing,? meaning your toes are moving away from the midline of your body.
When these three motions are extreme or excessive, overpronation results. Overpronation is very common in people who have flexible flat feet. Flatfoot, or pes planus, is a condition that causes
collapse of the arch during weight bearing. This flattening puts stress on the plantar fascia and the bones of the foot, resulting in pain and further breakdown.
HyProCure implant. A stent is placed into a naturally occurring space between the ankle bone and the heel bone/midfoot bone. The stent realigns the surfaces of the bones, allowing normal joint
function. Generally tolerated in both pediatric and adult patients, with or without adjunct soft tissue procedures. Reported removal rates, published in scientific journals vary from 1%-6%.
