For ACL reconstructions, a variety of graft options are available, including tissue from the patient (autograft) and tissue from a donor (allograft). For primary ACL surgeries, a majority of orthopaedic surgeons in the United States use autografts, including bone-patellar-tendon-bone and hamstring tendons. Regional variations favoring patellar tendon over hamstrings are found in some parts of North America and vice versa internationally. The use of allograft tissue is less common. This type of tissue is preferred by just 11% of surgeons in an international survey and 22% in the United States.
