Osteoarthritis (OA) is a disease which affects the joints in the body. The surface of the joint is damaged and the surrounding bone grows thicker. OA of the knee causes joint damage and swelling (inflammation) making it painful to move the knee.
Many factors seem to increase the risk of osteoarthritis developing in the knee joint. The risk increases with age, genetic factors, gender as it is twice as common in women as in men, obesity and previous injuries to the knee joint. Another according to latest research are altered gait mechanics and biomechanics in general (Farrokhi et al., 2017)
There are no cures for osteoarthritis. Medication and corticosteroid injections may help. Exercise is the best way to maintain joint surfaces and prevent further deterioration. Pain relief can be achieved with medication, ice and acupuncture.
