Depends if you have problems with cartlidge, otherwise no. Cartlidge is between bones to stop them grinding and to keep your movements smooth. With out it many problems would occur with the human body.

To proect their bones from breaking

Because we have a muscle called carpals that refil our bones once they get to the point that they can's stretch. ^_^
Cartilage is the soft and tough layer that covers the ends of the long bones. It is included in the joint. It protects the bones from wear and tear during the movement.
If bones did not have a softer material (cartilage) between them, then they would grind against each other, which would cause damage. The bones would wear out at the joints.
