Osteoarthritis is a degenerative joint disease that leads to wear and tear of the joints and affects the cartilage, joint lining, ligaments and bone.
It is the most common form of joint disease and tends to occur most often in the hand joints, spine, hip, knees and great toes. It is characterized by the breakdown of the joint cartilage, bony changes in the joints and deterioration of the tendons and ligaments leading to pain and inflammation of the joint lining.
