Knee Arthritis

Arthritis involves loss of the smooth lining covering the ends of bones in a joint called cartilage. In osteoarthritis, the cartilage becomes damaged and worn out, causing pain, swelling, stiffness and restricted movement in the affected joint. Unfortunately, there is no cure for arthritis and it tends to progress as we get older. As different parts of the knee wear out earlier than others, knee deformities can develop, such as knock-knees or bow-legged. A number of nonoperative treatments can help temporarily, but eventually most people will end up considering a joint replacement.
