Answer: The most traditional technique is to use metal screws. Alternatives include plastic screws, or screws which absorb into the body over time. Another widely used method is called suspensory fixation, when the graft is looped over a small metal implant the size of a grain of rice. Suspensory fixation is typically used on the femur (thighbone) side with a screw used on the tibial side. In some cases a metal staple is used to supplement the screw and this often requires removal at a later date. Newer techniques centre on suspensory devices at both top and bottom and have a system for tensioning the graft between the two such devices.
