Double-bundle Versus Single-Bundle Anterior Cruciate Ligament Reconstruction

DB: Two tunnels were created on the femoral side through an anteromedial portal. These tunnels were created manually. On the tibial side, the tunnels were created using a guide to ensure they matched the anatomic insertion site of the ACL at the tibia. The hamstring grafts for the procedure were then harvested from the same leg and doubled. The femoral side was fixed from the inside out, whereas the tibial side was fixed from the outside in. bioresorbable screws were used.

SB: The femoral tunnel was created using an anteromedial portal. A freehand technique was used. For the tibial tunnel, a tibial guide was used to ensure it was positioned at the midpoint of the tibial ACL attachment site. The tendons of the semitendinosus and gracilis muscles were then harvested, doubled over, and inserted through the tibial tunnel, extending into the femur, and fixed with metallic or bioabsorbable interference screws.
