Osteoarthritis is a degenerative mechanical condition that causes loss of cartilage resulting often in joint pain and sometimes loss of function, which involves the breakdown of cartilage in joints, such as the hands, hips and knees, and it’s particularly prevalent as people get older.
Some factors can increase risk, include a joint injury, being overweight, ageing, and genetics. Putting stress on a joint through repetitive motion can also increase your risk.
