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.
Bone remodeling. Repair after a fracture. During childhood, the long bones (in the arms, legs, and back) grow at the ends of the bones, whereas the flat bones (such as the skull) have a different pattern of growth. Adult bone actually continues to expand, although very slowly.Bone also continually undergoes remodeling, replacing old bone with new bone.hese precursor cells turn into osteoblasts which secrete collagen in a haphazard pattern called woven bone. Later osteoclasts resorb (dissolve) the woven bone and new osteoblasts form the mature, lamellar (layered) bone.
