Biomechanical evaluation of the femur–graft–tibia (FGT) complex. The FGT complex was mounted on a tensile tester using a set of specially designed grips. A tensile load was then applied to the grafted tendon parallel to its long axis. Cyclic testing was performed initially to simulate the tibial anterior drawer setting, followed by tensile testing. Failure modes were recorded. The structural properties (upper yield load, maximum load, linear stiffness and elongation at failure) of the complex were determined through software calculations.
