Between cartilage and bone which one heals faster?

Bone: Because bone has marrow in it (which produces the body's healing cells), it heals much more quickly than joint cartilage. Once joint cartilage is damaged, it is never quite the same and the type that grows back is not as smooth or as strong as the original. Bones heal with a great deal of strength, and are in fact stronger in the place they heal than the surrounding bone.
