Suspensory fixation devices are used to draw the graft in to the femoral tunnel. Tunnel lengths differ between patients as do graft lengths. With a fixed length suspensory loop, once the metal device to fix the graft in the femoral tunnel has been deployed, it cannot be adjusted. In theory, fixed length suspensory loops may result in insufficient graft in the femoral tunnel. Whilst fixed suspensory loops are available in a multitude of sizes to overcome this problem, this will necessitate keeping a large stock of differing size products available in the operating theatre which will incur cost repercussions. With an adjustable suspensory loop, the graft can continue to be pulled up into the femoral tunnel even after the fixation button is attached to the outer femoral cortex giving the operating surgeon greater intra-operative flexibility. This will allow a greater amount of graft to be drawn within the femur. If one can have a short length of suspensory loop and a greater amount of graft in the tunnel, there will be less motion of the graft in the tunnel and a greater ability of the graft to unite to the surrounding bone.
