Autograft, tissue transplanted from one site to another on the same patient. An autograft reduces the risk of rejection but requires a second surgery site, adding pain, risk and possible longer aftercare. Xenograft, a transplant from another species; Isograft, a transplant from a genetically identical donor, such as an identical twin.
An allograft contains many of the beneficial characteristics of nerve autograft, such as three-dimensional microstructural scaffolding and protein components inherent to nerve tissue. [3] One of the adverse effects of nerve allotransplantation is the immunogenic response.
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between identical twins.
Sometimes an autograft is done to remove the tissue and then treat it or the person before returning it [8] (examples include stem cell autograft and storing blood in advance of surgery). In a rotationplasty , a distal joint is used to replace a more proximal one; typically a foot or ankle joint is used to replace a knee joint.
Hence, similar tissue from another part of the body that is in excess is sourced as the autograft. [10] [11] This can be seen in procedures like autologous orthopedic transplant, which remains the "gold standard" of bone grafting methods through extracting grafts from places like the iliac crest and transplanting them to the targeted fracture ...
This kind of graft is known as a vital bone graft. [citation needed] An autograft may also be performed without a solid bony structure, for example, using bone reamed from the anterior superior iliac spine. In this case, there is an osteoinductive and osteogenic action, however, there is no osteoconductive action, as there is no solid bony ...
Labral reconstruction is a type of hip arthroscopy in which the patient's native labrum is partially or completely removed and reconstructed using either autograft or allograft tissue. Originally described in 2009 [ 1 ] using the ligamentum teres capitis, arthroscopic labral reconstruction using a variety of graft tissue has demonstrated ...
