Allograft ACL Reconstruction
In allograft ACL reconstruction, tendons are taken from human donor rather than your own body (autograft ACL reconstruction). The primary advantage of allograft tissue is that there is no additional damage to the knee and stronger grafts can be used.
The most common allografts use the patellar tendon and Achilles tendon. The Achilles tendon is the strongest and largest tendon in the body. Allograft tissues are taken from tissue donors through tissue banks. The donors are people usually under 40 years of age, often who have died from an accident. The donors are screened by tissue banks and are tested for infectious diseases. Screening histories, blood tests and cultures are obtained during tissue processing. These screening procedures must be clear of infectious disease or the tissues are rejected by the tissue bank.
Risks of Disease from AllograftsThe risk of disease transmission through allografts while never non-existent is extremely small. Allografts are poor vectors for disease transmission. The graft tissue has no living cells. It is frozen and kept in a deep freezer until used. The fact that the tissue has only a few cells and no living cells makes the donor graft tissue a poor transmitter of living bacteria or viruses that are responsible for transmitting most diseases. Because this tissue has no living cells, it is not necessary to match the donor and recipient, nor is it necessary to give anti-rejection drugs.
