The trephine is removed and the articular cartilage and cancellous bone is morselized in a graft impactor; The graft paste is re-loaded into the trephine and impacted into the fractured bed of the chondral defect; The paste graft is held in place for 1 to 2 minutes
Demineralized bone matrix (DBM) is allograft bone that has had the inorganic mineral removed, leaving behind the organic "collagen" matrix. It was first discovered by Marshall Urist in 1965 that the removal of the bone mineral exposes more biologically active bone morphogenetic proteins . [ 1 ]
Bone grafts may be autologous (bone harvested from the patient's 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. Most bone grafts are expected to ...
Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year.

Bone grafting – used in dental implants, as well as other instances. The bone may be autologous, typically harvested from the iliac crest of the pelvis, or banked bone/allograft. [2] Vascular grafting – the use of transplanted or prosthetic blood vessels in surgical procedures.
Allografts can be referred to as "homostatic" if they are biologically inert when transplanted, such as bone and cartilage. [2] An immune response against an allograft or xenograft is termed rejection. An allogenic bone marrow transplant can result in an immune attack on the recipient, called graft-versus-host disease.
A meniscus transplant or meniscal transplant is a transplant of the meniscus of the knee, which separates the thigh bone from the lower leg bone . The worn or damaged meniscus is removed and is replaced with a new one from a donor. The meniscus to be transplanted is taken from a cadaver, and, as such, is known as an allograft.
Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its de novo bone formation properties. [1] It is used extensively in bone grafting of alveolar bone in oral and periodontal surgery.
