Information on osteoarthritis is available on many websites, including those for Mayo Clinic, WebMD, the Arthritis Foundation and Everyday Health. Osteoarthritis develops when the protective cartilage at the ends of bones wears down, leading to joint pain, stiffness and swelling, states the Arthritis Foundation.
Risk factors for developing osteoarthritis include genetics, injury, overuse and being overweight, according to the Arthritis Foundation. Individuals with other bone, joint or metabolic disorders are also at increased risk of developing osteoarthritis. While osteoarthritis does not have a cure, many treatment options relieve symptoms and keep joints mobile, notes Mayo Clinic. Some of these treatments include medications, physical therapy, cortisone injections and joint replacement.
