Osteoarthritis, also known as degenerative joint disease (DJD), is the most typical form of arthritis. Osteoarthritis is more common as people get older. Osteoarthritis usually worsens gradually over time, but there are some rare cases where it can accelerate suddenly. Pain, swelling, and deformity are all possible outcomes of joint inflammation and injury, as well as changes to the bone, weakening of the tendons and ligaments, and destruction of the cartilage that cushions the joints. There are two types of osteoarthritis, degenerative and progressive.
