An ACL reconstruction requires placementt of a graft. A graft is tissue that is placed in your body to repair a defect or damage. In this case, the graft is replacing the torn ACL. There are at least three choices your doctor can use for a graft. These include: the hamstring tendon, the patellar tendon, or an allograft. An allograft is a tendon that comes from a cadaver.
Each type of graft has advantages and disadvantages. For the allograft, there is less pain after surgery and because the graft is not removed from the patient, there are no possible complications from the graft removal. However, there is a small risk of transmitting disease and possible rejection of the graft. The allograft also takes longer to heal, which may change your rehabilitation and when you can return to sports activities.
