The symptoms of knee pain include pain in one or both knees that may be localized to one side of the knee, under the kneecap, or across a larger area. The pain may be a constant dull ache or may occur only during specific movements – or it can be severe, making walking difficult or even intolerable. Knee pain can begin at the actual joint or in the surrounding soft tissue and related muscles.
What causes knee pain?
In addition to trauma, the cause of knee-related pain results from acute or chronic maladapted neuromuscular function.
Acute functional problems occur when the body is pushed beyond its everyday functional capabilities.
Chronic functional problems occur gradually, when everyday activities don’t promote healthy function. Usually, these problems don’t cause pain or discomfort until the stress-related tissue damage builds to the point that it impedes movement.
In either case, most knee-related functional problems occur because of poor or maladapted neuromuscular function in the feet.
There is a direct biomechanical relationship between foot function and the way the legs and hips function.
An unstable foot, with a poorly functioning arch system, will result in poor bone alignment and imbalanced muscle use throughout the legs and hips. Over time, this maladapted foot, leg, and hip neuromuscular function becomes the norm and is the major contributing cause of virtually all nontraumatic knee pain.
