Besides these ligaments, additional stability is provided to the joint by the surrounding muscles, and this is not to be underestimated. So for example, around the shoulder joint, there are muscles that we commonly call the rotator cuff muscles. They are a very important stabilizing component for the shoulder joint, and they do stabilize the joint, but that further complicates an accurate diagnosis of a minor injury or a rupture of a ligament.
Through this temporary stabilization by the muscles, a joint might appear perfectly fine and healthy, but is it really? Why does it hurt? And this is where there are two things where doctors can truly help. Two things that I would like to explain.
