Pronation of the foot with many overuse injuries in running including medial tibial stress syndrome, or shin splints, and knee pain Hintermann states, “Individuals with injuries typically have pronation movement that is about two to four degrees greater than that of those with no injuries.” He adds however, that between 40% and 50% of runners who overpronate do not have overuse injuries. This suggests that although pronation may have an effect on certain injuries, it is not the only factor influencing their development. The design principles of foot orthoses are founded on knowledge of the functional anatomy of the foot. Pronation of the foot
Tibial plateau fracture involves a varus force with axial loading at the knee. Represent 10% of all tibial plateau fractures. There is high risk of damage to the popliteal artery and peroneal nerve and therefore carry a worse prognosis. May include distraction injuries to lateral collateral ligament, fibular dislocation/fracture, posterolateral corner. Consists of a split fracture of the medial and lateral tibial plateau. It is usually the result of a high energy injury with complex varus and valgus forces acting upon the tibial plateau. May include injuries to the anterior cruciate ligament and collateral ligaments. Make up 3% of all tibial plateau fractures.
