The hinge joint is basically a hinge. It can move up and down or from side to side, but | The hinge joint is basically a hinge. It can move up and down or from side to side, but within a 180<sup>o</sup> range. A very common example of this is a person's elbow or knee. Hinge joints usually have a lot of stress placed on them, and the knee is a very common example of this. Knee surgery is more common than any other surgery performed on a joint, because they are used rigorously each day. They are the joints that move you up, down, forward, and they have to carry all of your weight. This stresses the knee joint so much that it is not uncommon for even an average person to damage them in some way. | ||
