Arthritis and arthrosis fall into the broader category of rheumatic diseases, both affect the joints and both are characterized by pain accompanied by stiffness and limitation in the movements of the affected joints. It is precisely these similarities that sometimes lead to confusion between arthrosis and arthritis, often mistaken for each other. Yet they are two very distinct diseases that differ in different points. First of all, the nature of the disease and the age of those affected: arthritis is a chronic inflammatory disease of autoimmune origin that can develop in people of all ages, even in children, while osteoarthritis is a degenerative disease that arises especially after the age of 50.



Arthritis occurs with joint inflammation characterized by swelling, redness, stiffness, temperature rise in the affected area and pains that also result in loss of motor capacity of the affected joints. Stricter shapes can deform joints, compromising the ability to perform even the simplest everyday tasks. It can affect people of all ages and as the years go by the inflammation tends to get worse if not properly recognized and cured. There are several types of arthritis, including rheumatoid arthritis (also in its juvenile form), gout, and arthritis in the context of connective diseases such as systemic lupus erythematosus.

Arthrosis, unlike arthritis, is not an inflammatory disease, but a chronic degenerative form. It particularly affects people later in life because it is related to joint wear. The joint structures that are most frequently affected are those that are most stressed by weight and activity, including knees, hips, shoulders, hands, feet and spine. The degenerative process of osteoarthritis leads to a thinning of the articular cartilage and to bone deformities that cause pain and specific symptoms of osteoarthritis, particularly evident in the distal phalanges of the hands, for example.
