Overpronation is when the foot rolls in excessively, or at a time when it should not, for instance late in the stance phase of gait. In this case much weight is transferred to the inner or medial
side of the foot, and as the runner moves forward the load is borne by the inner edge rather than the ball of the foot. This destabilises the foot, which will attempt to regain stability by
compensating for the inward movement. In a kind of chain reaction, this in turn affects the biomechanical efficiency of the leg, especially the knee and hip.
Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Over-pronation is also very common with athletes,
especially runners and most of them nowadays use orthotics inside their shoes. Over-pronation affects millions of people and contributes to a range of common complaints including sore, aching feet,
ball of foot pain, heel Pain, achilles tendonitis, bunions, shin pain, tired, aching legs, knee pain and lower back pain. The most effective treatment solution for over-pronation is wearing an
orthotic shoe insert. Orthotics correct over-pronation, thereby providing natural, lasting pain relief from many common biomechanical complaints.
Eventually, over-pronation can lead to a full list of maladies including flat feet, plantar fasciitis, plantar fibroma, neuromas, heel spurs, shin splints, ankle sprains, bunions, hammertoes,
calluses, and pain in the arches, knee, hip and lower back. But it doesn?t have to go that far, because there are steps we can take to correct the over-pronation. In the vast majority of cases, we?ll
prescribe custom foot orthotics, which will realign your ankles, redistribute the weight, support the arch and reduce the twisting. Many orthotics will fit snugly into your normal shoes. Although
we?ll also take a look at the type of shoes you wear to see if they are contributing to the problem.
People who overpronate have flat feet or collapsed arches. You can tell whether you overpronate by wetting your feet and standing on a dry, flat surface. If your footprint looks complete, you
probably overpronate. Another way to determine whether you have this condition is to simply look at your feet when you stand. If there is no arch on the innermost part of your sole, and it touches
the floor, you likely overpronate. The only way to truly know for sure, however, is to be properly diagnosed by a foot and ankle specialist.
Non Surgical Treatment
Studies have shown that the most effective way to dexrease a high Q angle and lower the biomechanical stresses on the knee joint is to prevent excessive pronation with custom-maflexible orthotics.
One study found that using soft corrective orthotics was more effective in reduknee pain than a traditional exercise program. A more recent study showed that Q angle asymmetries, secondary to
excessive pronation affecting knee alignment, can be effectivecontrolled or corrected utilizing custom-made, flexible orthotics. Another project involving meof a running club determined that 75% of
those using orthotics eliminated or greatly reduced pain in the feet, ankles, shins, knees and hips
Hyperpronation can only be properly corrected by internally stabilizing the ankle bone on the hindfoot bones. Several options are available. Extra-Osseous TaloTarsal Stabilization (EOTTS) There are
two types of EOTTS procedures. Both are minimally invasive with no cutting or screwing into bone, and therefore have relatively short recovery times. Both are fully reversible should complications
arise, such as intolerance to the correction or prolonged pain. However, the risks/benefits and potential candidates vary. Subtalar Arthroereisis. An implant is pushed into the foot to block the
excessive motion of the ankle bone. Generally only used in pediatric patients and in combination with other procedures, such as tendon lengthening. Reported removal rates vary from 38% - 100%,
depending on manufacturer. 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
