Stepwise demonstration of the “Bridge-Enhanced ACL Repair” technique using the scaffold. In this technique, the torn ACL tissue is preserved (A). A whip stitch of #2 absorbable suture (purple suture) is placed into the tibial stump of the ACL. Small tunnels (4 mm) are drilled in the femur and tibia and a suture cinch comprised of a cortical button with two #2 non-absorbable sutures (green sutures) and the #2 absorbable ACL sutures are passed through the femoral tunnel and the button engaged on the proximal femoral cortex. The non-absorbable sutures are threaded through the scaffold, tibial tunnel and secured in place with a second extracortical button. The scaffold is then saturated with 10 mL of the patient’s blood (B), and the tibial stump pulled up into the saturated scaffold (C). The ends of the torn ACL then grow into the scaffold and the ligament reunites (D). Used with permission from Murray et al, OJSM 2016.³⁸
