Explain the degeneration process in osteoarthritis
What will be an ideal response?
Answer: Degeneration occurs at the articular cartilage that caps the bone surface where bone meets another bone in a joint. As this cartilage degenerates, underlying bone becomes exposed and damaged, which leads to new bone deposits in and around the joint. The bone ends thicken and develop sharp irregular bone surface structures called spicules and spurs. As a result, small joints such as the knuckles enlarge and become knobby.
