Osteoarthritis, also called degenerative joint disease is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage).In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint.
Osteoarthritis is caused by the wearing out of the cartilage covering the bone ends in a joint. This may be due to being overweight, excessive strain over prolonged periods of time, previous fracture, growth abnormalities, joint diseases, injury or deformity.
Some people have congenital abnormalities of the joints that cause early degeneration and subsequently cause osteoarthritis.
Doctors diagnose osteoarthritis with a medical history, physical exam and x-rays of the affected joint. During the physical examination your doctor will examine the affected joint for swelling, pain, tenderness, and assess the joint’s range of motion. An X-ray of the knee may show a loss of the joint space and bone spur formation.
There is no blood test for osteoarthritis.
