The quadriceps muscle runs from the front of your hip down your thigh and courses through the patella. If certain regions of this muscle are “tight” or “weak” it can steer the train, or your patella, off the tracks causing excessive friction to structures underneath. Most athletes will compensate until they no longer can, leading to pain and/or wear and tear to the joint.
Your knee is a reactive hinge joint, meaning that it adapts to forces placed above and below it (ankle and hip). Just like a door hinge, you should be able to swing that door open and closed all day with no disruptions. While treating pain at the knee is important for reducing your symptoms and, therefore function, we also pride ourselves in addressing the joints above and below in order give you the best biomechanical advantage for reducing risk of further injury.
For example, the hip plays an important role in controlling a moment of internal rotation and adduction at the knee. The ankle/foot is responsible for dissipating ground reaction forces, however, having a high arch or low arch can allow these forces to be placed poorly over the knee joint.
