The knee is a simple hinge joint, but it is very densely packed with nerves that control its stability. There may be physical arthritic changes or damage to certain structures (like cartilage or ligaments).
Or a problem elsewhere, where another part of the body is not aligned or moving properly, could be putting excessive strain on the knee joint leading to pain. The nerves in the knee come from the lower back and pelvis, so these regions need to be examined too when assessing your knee.
We approach knee pain by first seeing if there is any physical damage or arthritic changes within the knee itself, and then looking at how dysfunction somewhere else, like your low back or pelvis, might be affecting your knee. This way we aim to get longer lasting results by addressing the underlying causes.
