A bone graft is a surgical procedure used to fix problems associated with bones or joints. Bone grafting or transplanting of bone tissue is beneficial in fixing bones after trauma, problem joints, or growing bone around implanted devices, such as total knee replacement (TKR).he two most common types of bone grafts are: 1  allograft: this graft uses bone from a deceased donor or a cadaver that has been cleaned and stored in a tissue bank. 2  autograft: graft made from a bone inside a patientâs body, such as the ribs or hips.
In the very young, the skeleton is composed largely of cartilage and is therefore pliable, reducing the incidence of bone fracture and breakage in childhood. The inorganic, or mineral, content of bone is mainly calcium, phosphate and carbonate minerals. The organic content is a gelatinous material called collagen.As the body grows older, decreases in bone mass may lead to an increased vulnerability to fractures.one is a dynamic tissue and is constantly being remodeled by the actions of osteoclasts and osteoblasts. After bone removal, the osteoclasts either move on to new resorption sites or die; this is followed by a reversal phase where osteoblasts are attracted to the resorption site.
