The Biomechanical Effects Of 1.0 To 1.2 Mrad Of Γ Irradiation On Human Bone-Patellar Tendon-Bone Allografts

Background: Recent data suggest that anterior cruciate ligament (ACL) reconstruction with irradiated allograft tissue may lead to increased failure rates.

Conclusion: Low-dose (1.0-1.2 Mrad) gamma irradiation decreases BTB graft stiffness by 20%, but it does not affect other failure or cyclic parameters.
