Regardless of the fact that bones have a tremendous capacity to be repaired, there are various clinical situations where allographs seek to enhance the regeneration of bones through promotion of osteogenesis . Precarious botches linked to the present grafting treatments include osteonecrosis along with restricted combination between the grafted and host tissues. It is considered that the fundamental issue with the present approaches to bone grafting is the fact that they lead to bone regeneration by means of direct osteogenesis. Therefore, it may be hypothesized that the use of cartilage in the promotion of endochondral regeneration of bones may leverage normal development and repair sequences resulting in a properly vascularized regenerate capable of integrating with the host tissues. Various tests have demonstrated that cartilage grafts are able to support the regeneration of vascularized and integrated bone tissues in vivo, while lineage tracing experiments have revealed graft derived regenerates.
