"Please explain the pathophysiology of osteoarthritis to me," says another nurse. "Is it just wear and tear so that the cartilage wears out?" Your best response is a. "Yes; with increasing age, the inflammation from repeated joint use accumulates and causes the cartilage to get thin and ragged until it disappears." b. "Yes; repeated use just wears out the cartilage, until it becomes thin and denuded. That causes pain and will eventually cause joint inflammation." c. "No; autoimmune cells infiltrate the joint and collect on the cartilage in a mass called 'pannus' that eventually thins and destroys the cartilage." d. "No; cells in bone, cartilage, and the synovial membrane all get activated and secrete inflammatory mediators that destroy cartilage and damage bone."
