Osteoarthritis is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. A form of arthritis, it is believed to be the fourth leading cause of disability in the world, with an estimated 240 million people worldwide having activity-limiting osteoarthritis. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two

AI overview

Osteoarthritis is a degenerative joint disease that occurs when the cartilage and bone within joints break down, causing pain, stiffness, and reduced movement. It affects an estimated 240 million people worldwide and is considered the fourth leading cause of disability globally, making it a significant health concern.

Osteoarthritis is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. A form of arthritis, it is believed to be the fourth leading cause of disability in the world, with an estimated 240 million people worldwide having activity-limiting osteoarthritis. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected.

Possible causes include previous joint injury, abnormal joint or limb development, and inherited factors. Risk is greater in those who are overweight, have legs of different lengths, or have jobs that result in high levels of joint stress. Osteoarthritis is believed to be caused by mechanical stress on the joint and low grade inflammatory processes. It develops as cartilage is lost and the underlying bone becomes affected. As pain may make it difficult to exercise, muscle loss may occur. Diagnosis is typically based on signs and symptoms, with medical imaging and other tests used to support or rule out other problems. In contrast to rheumatoid arthritis, in osteoarthritis the joints do not become hot or red.
