"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
-"Yes; repeated use just wears out the cartilage, until it becomes
thin and denuded. That causes pain and will eventually cause
joint inflammation."
-"Yes; with increasing age, the inflammation from repeated joint
use accumulates and causes the cartilage to get thin and ragged
until it disappears."
-"No; cells in bone, cartilage, and the synovial membrane all get
activated and secrete inflammatory mediators that destroy
cartilage and damage bone."
-"No; autoimmune cells infiltrate the joint and collect on the
cartilage in a mass called 'pannus' that eventually thins and
destroys the cartilage." correct answers "No; cells in bone,
cartilage, and the synovial membrane all get activated and
secrete inflammatory mediators that destroy cartilage and
