If the left sided outflow root needs to be enlarged to fit the pulmonary autograft, the procedure is called Ross-Konno. [3] An alternative to a pulmonary homograft is the stentless xenograft roots such as the Freestyle Porcine Aortic Root by Medtronic. [2] [12] An external Dacron graft can be used to reinforce the pulmonary autograft. [2]
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.
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 ...
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.

Sir William Macewen, who reported a case of successful autograft cranioplasty in 1885. Autografts, or autologous grafts, are body tissues taken from the patient. The first successful cranioplasty using an autograft was recorded in 1821, with the bone piece being reinserted into the cranium. The operation achieved partial healing.
