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 grafts may be autologous (bone harvested from the patientâs own body, often from the iliac crest), allograft (cadaveric bone usually obtained from a bone bank), or synthetic (often made of hydroxyapatite or other naturally occurring and biocompatible substances) with similar mechanical properties to bone.steogenesis only occurs with autograft tissue and allograft cellular bone matrices, such as Trinity ELITE (MTF/Orthofix), BIO4/Stryker) and Osteocel Plus (AlloSource/NuVasive).
