The Knee Degenerative Joint Disease
Cynthia Laportilla, Physical Therapist with Miami Orthopedics and Sports Medicine Institute, explains when a knee that has some degenerative changes in either some of their joints or all of their joints or has an osteoarthritis problem, it just has to do with the bones and cartilage, and other times it is an autoimmune or a rheumatic arthritis type of problem.
She points out the surfaces of the joint should be like smooth wet ice; when you have arthritis you have inflammation in the joint, and that inflammation causes wearing and breaking down of the cartilage, and that cartilage can wear down all the way down to the bone. "Bone is never really meant to come in contact with another bone, so by the time you get to bone on bone it can be a very painful condition."
