Final answer:
The graft material taken from a cadaver for an ACL reconstruction surgery is called an allograft.
Step-by-step explanation:
The graft material taken from a cadaver for an ACL reconstruction surgery is known as an allograft.
An allograft is a type of graft where tissues are transplanted from one genetically distinct individual to another within the same species. In this case, the cadaver serves as the donor for the graft material.
Using an allograft can be advantageous as it eliminates the need for an additional surgical site to harvest a graft from the patient's own body, reducing the risk of surgical complications.
