Osteoarthritis in elderly

Osteoarthritis is characterized by the breakdown of cartilage in joints. As cartilage deteriorates, the bones of the joint begin to run against one another, causing stiffness and pain, which often impairs movement. Osteoarthritis also can damage ligaments, menisci, and muscles. Bone or cartilage fragments may float in the joint space, causing irritation and pain. Bone spurs, or osteophytes, may also develop, causing additional pain and potentially damaging surrounding tissues. Around the world, an estimated 10%-15% of adults over 60 have some degree of osteoarthritis. It most commonly affects the joints in the knee, hands, feet, and spine, and is also relatively common in other joints such as the shoulder and hip joint
