Allografts are biological tissues transplanted from one individual to another of the same species. They are commonly used in medical procedures, such as orthopedic surgeries, to replace damaged or missing tissues. Allografts can include bone, skin, tendons, and organs, and they help improve healing and restore function. The use of allografts reduces the need for harvesting tissue from the patient, minimizing surgical risks and recovery time. However, because allografts come from donors, there is a risk of rejection by the recipient's immune system. To mitigate this, medical professionals often use immunosuppressive medications to help the body accept the transplanted tissue.
