ANS: C
Unless an injury breaks through the uncalcified cartilage layer, known as the tidemark, it is
unlikely that it will heal. If an injury breaks through this layer, it is likely that the blood supply
from the subchondral bone may play a role in forming new fibrocartilage in place of hyaline
cartilage. This may lead to endochondral ossification over time, but it is the only opportunity
cartilage has for self-repair.
