Injury Prevention: Foot, Ankle and Knee

The most common foot problem is overpronation and lack of dorsiflexion. An over pronated foot utilizes the lateral gastrocnemius more than usual during propulsion. This causes the gastrocnemius to shorten over time. A shortened, tight and weak gastrocnemius limits the range of motion of dorsiflexion and activation of the dorsi flexors. Dorsiflexion is required for the body to maintain alignment. The patient is likely to have a toe-out gait causing propulsion off the 1st MTP instead of all five toes due to lack of dorsiflexion. The increased pressure placed at the 1st MTP will cause callusing and/or bunions. In addition, overpronation causes increased stress on the knee. When an individual over pronates the tibia and femur internally rotate which results in knee adduction. Every step a person takes has a load of 2.5 times their body weight. If the foot does not properly absorb the extra load, an increased amount of stress will travel to the knee. In order to prevent overpronation, the arch of the foot needs to have increased support until the foot is able to function properly on its own. The forefoot and rear foot will need to be aligned with medial support (posting). This will position the foot in alignment with the body including the knee. A properly aligned foot and ankle will allow the patient to go through gait correctly by supinating at the heel, proceeding through moderate pronation at mid-stance, then propulsion off all five toes. Positioning the foot to move through gait properly will decrease the amount of pressure at the foot reducing the stress that travels to the knee. In addition to a good arch support the foot should have extra cushioning to absorb stress that travels up the tibia which may cause shin splints, stress fractures, knee pain, etc. It is essential for the foot to be aligned to increase mobility at the ankle and stability at the knee to reduce discomfort and future problems.
