A joint is the place where two or more bones come together, for example, the knee, hip, and shoulder. When a damaged joint is replaced with a new one it is called joint replacement. Typically the joints that bear the most weight such as knees and hips are the most problematic.
There are several causes that contribute to joint problems. Joint problems may be inherited; arthritis, physical structure deficiencies such as uneven fitting of joints, and bone positioning. Excess weight causes unnecessary stress on the joints and breaks down cartilage. Because exercise is important for sufficient lubrication of the joints, a sedentary lifestyle is detrimental to joints and the surrounding muscles which are weakened. Repeated stress on a joint that athletes and anyone who performs a repetitive motion over a long period of time encounter may cause joint problems. A previous injury may lead to joint pain at a later time.
A damaged joint causes pain, swelling, stiffness and decreased range of motion. Since the year 2000, joint replacement surgery has been on the rise. The improvement in technology has made joint surgery more effective and more readily available for treating damaged joints.
