OC Femoral Cannulated Reamers are specialized designed reamers for femoral tunnel drilling in arthroscopic ACL reconstruction. Featuring calibrated markings on sides of its shaft, this allows for easy and accurate identification of the tunnel depth. This minimizes the risk of injury to the PCL by providing ample control when reaming the femoral tunnel from the inside-out. They are available in diameter ranging from 6mm to 12mm with 0.5mm differences.
