M15-M19: Arthrosis

Arthrosis, more commonly known as osteoarthritis, is a range of joint conditions characterized by the breakdown and eventual loss of the cartilage of one or more joints. This breakdown occurs predominantly due to aging and wear and tear, though other factors like injury, genetic predisposition, and obesity can also contribute. Typical symptoms include joint pain and stiffness, particularly after periods of inactivity or excessive use, and reduced flexibility, physical function, and quality of life. Arthrosis can affect any joint, but it most commonly affects hands, knees, hips, and the spine. Disease progression is typically slow and can lead to changes in joint appearance, such as bony growths or deformities, over time. The exact experience and severity of symptoms can greatly vary from person to person.
