Schematic diagram depicting the primary suture repair with the collagen-platelet composite scaffold in place. Sutures were fixed proximally with an EndoButton device. The sponge was threaded onto four of the trailing suture ends (purple), which were then passed through the tibial tunnel and tied over a button to provide initial knee stability. The remaining two suture ends (green) were tied to the sutures in the tibial stump of the anterior cruciate ligament.
