The graft complex is actually at its weakest at around the 6 week post operative mark. Kinematic research has shown that open chain exercises cause significantly more anterior tibial displacement and hence more strain on the graft than closed chain exercises.

Conclusion: The maximum compressive stress, von Mises stress and shear stress of the ACL graft are located in the anterior femoral end, and the maximum tensile stress is located in the posterior femoral end, which is consistent with the position of the maximum tensile stress of the ACL of the uninjured knee joint.
