Fluoroscopic assist in anterior cruciate ligament reconstruction.
When creating the femoral tunnel during endoscopic anterior cruciate ligament reconstruction, the potential exists for penetration of the posterior femoral cortex. In addition, during placement of the proximal fixation screw, the screw can deviate from its intended path. We have used an image intensifier intraoperatively to obtain a lateral view of the knee to enable the assessment of tunnel placement and screw alignment. This technique assures the accurate placement of the tibial and femoral tunnels and helps avoid screw divergence from the graft.
