Allografts are transplanted organs or tissue from one individual to another of the same species with a different genotype. For example, a transplant from one person to another, but not an identical twin, is an allograft. Allografts account for many human transplants, including those from cadaveric and living donors. Also known as an allogeneic graft or a homograft.
The most common source of allograft is via the donation of the femoral head, (medical term) for the part of the hip joint that is removed during hip replacement surgery. This is termed a living donation. Australian Allografts is committed to encouraging patients to become donors so that this critical source of bone graft can be collected, processed and distributed to enhance the life of a recipient in desperate need.
The other source of allograft is cadaveric, or deceased donation. This occurs with the consent of the next of kin, someone who had indicated a wish to donate during their lifetime, can leave an altruistic gift when they pass away, which can then enhance the lives of others.
