Are cartilage cells unable to go through mitosis?

Complex issue.
Cartilage *does* in fact repair itself - but only to a limited degree. Small injuries can be repaired, but larger lesions cannot. In fact, one form of surgery to encourage damaged cartilage to repair itself involves actually cracking the cartilage, and moving the bits into a larger injury - producing lots of smaller lesions that - hopefully - the body *can* repair. This is called "mosaicplasty" (one of my favourite names for a medical procedure)
Chondrocytes (cartilage cells) *are* capable of multiplying in vitro (in a petri-dish) - but they seem to have a limited capability to do so in vivo (in the organism).
One likely reason is that cartilage has no blood supply - which will limit the supply of nutrients and oxygen to the chondrocytes.

Its not that cartilage cells doesnot undergo mitotis division but it is due to the fact that all body parts cannot repair itself because for repairing of any body parts require a protein sequencing this sequencing is pre programmed even before our birth during fertilisation their are certain specialised cells called stem cells which are capable of dividing into any cell type and these stem cells could be referred as primary source of production for any cell type but these cells are not produced in our body after complete development of our body therefore body parts such as bone and cartilages are not regenerated due to absence of these of cells.

Cartilage is poorly vasculated and the blood stream can not easily deliver repair materials to it. Not all tissues are equally able to make repairs via cell division.

no, chondrocytes are fully capable of dividing. however, the cellular mass of cartilage is less than 1% of the total tissue mass. the tissue itself is made of of collagen (for structure) and high molecular proteoglycans (for cushioning). the cells make up just a miniscule amount of the tissue, so they have a very difficult time repairing injuries.

The body can repair its self if it has the material to repair it's self.

It does.
