or ligament 80 and a tibial device 30 all integrated into a single unit 100 saving time for fixation of the system the assembly provides cortical fixation on both femur and tibia with buttons each of the loops of each of the self locking adjustable knotless constructs 10 is adjustable under tension as shown by arrows f 1 f 2 of fig1 the surgeon simply pulls on both ends of the final construct 100 to adjust the length l of each flexible loop and to tighten therefore the construct in this manner there is no need for the surgeon to calculate in advance the proper graft length i e the length of the soft tissue graft or of a btb graft which in turn is based on calculating the entire length of the tunnels sockets i e the entire lengths of the femoral and tibial tunnels sockets plus the intraarticular space between them fig1 shows the final assembly 100 of the present invention being introduced and secured into both a femoral tunnel socket 91 and a tibial tunnel socket 93 of knee 15 typically through an arthroscopic portal the buttons 20 are pulled out of the bone cortex with the passing sutures which are later.
