Definition of Degenerative Arthritis
Degenerative Arthritis, or osteoarthritis, is a type of arthritis caused by inflammation, breakdown and eventual loss of the cartilage of the joints. Among the many different types of arthritis conditions, osteoarthritis is the most common, affecting the hands, spine, feet and large weight-bearing joints (such as the hips and knees). It is also known as degenerative joint disease. Primary osteoarthritis is mostly related to getting older. With aging, the water content of the cartilage increases and the protein of the cartilage degenerates. Continuing use of the joints over the years irritates and inflames the cartilage, causing pain of the joints and swelling. Eventually, cartilage begins to degenerate by flaking and forming tiny crevasses. In advanced cases, there is a total loss of the cartilage cushion surrounding the bones/joints. Loss of cartilage cushion causes friction between the bones, leading to pain and limitation of mobility. Inflammation of the cartilage also stimulates new bone outgrowths (spurs) to form around the joints. Osteoarthritis can occasionally be found in multiple members of the same family, implying heredity or genetic basis for the condition.
