Bones can wear down - in a sense. Bones are not rock solid dead matter. Quite the contrary. A bone in a live human body is living tissue. They are also quite porous. Bones can get denser or less dense depending on circumstances. For example they will grow more dense if they are more heavily used and vice-versa. Bones can also lose density (break down) if there is a sufficient lack of calcium and/or vitamin D in your diet, i.e. osteoporosis.
or if that's not what you mean... cartlidge is in between the joints to stop them from grinding and wearing down, so movement will be smooth.
