Genetic traits, being overweight, repetitive injuries or overuse may all lead to Osteoarthritis. Some may have inherited a small misalignment of how the bones of the joint fit together, causing the cartilage to wear away more quickly. Those who are overweight have extra pressure on the joints, as researchers have found that excess fat tissues create cytokines or inflammatory chemicals that may injure the joints. Injuries to the joints that are caused by overuse or damage may also rapidly increase the loss of cartilage.
Though Osteoarthritis has a variety of symptoms depending on the joint affected, it has common symptoms of pain and stiffness of the joints. The joints affected may become inflamed, especially after continued activity.
There may be a limited range of motion of the joint, cracking sounds when the joint is bent, swelling, or pain that becomes worse as the day goes on.
