Degenerative joint disease or Arthritis is most common in those 65 years and older although it can affect people of all ages. The most common form of arthritis is Osteoarthritis (OA) where wear and tear on the joints leads to degradation of the normally smooth cartilage which lines the bones. The loss of healthy cartilage results in bone rubbing on bone. The disease causes inflammation in the joints resulting in pain and immobility, ranging from mild to severe. The degree of severity is important as it will ultimately determine the type of treatment which is most appropriate for the stage of the disease that the individual is at and also treatment expectations.
