ACL Reconstruction Surgical Technique Guide Using Interference Screw

Preparation & Graft Passing Figure 1 The knee is prepared for arthroscopic surgery using standard methods to place portals. A graft is obtained and prepared for reconstruction through standard procedures. The femoral and tibial tunnels are prepared with the appropriate angles and parameters (Figure 1). The tunnel depth should be the length of the interference screw at the minimum, and tunnel diameter should be equal to the screw diameter. Once the tunnels have been created, use a passing suture to pass the graft into the joint through the tibial tunnel and then femoral tunnel (Figure 2). Maintain...

Graft Fixation Figure 4 Place a guidewire in the femoral tunnel. If desired, the surgeon may tap over the guidewire to create a pre-threaded hole for the interference screw. Remove the tap and place the screw securely on the screw driver. Insert the interference screw over the guidewire and into the knee joint (Figure 4). Maintaining tension on the graft, fix the femoral side of the graft with the interference screw in standard fashion (Figure 5). The screw should be advanced until the head is counter sunk slightly in the femoral tunnel. Place a guidewire into the tibial tunnel, and if desired,...
