title: Double incision iso-anatomical ACL reconstruction: the freedom to place the femoral tunnel within the anatomical attachment site without exception.
abstract: OBJECTIVE
  The present paper describes the rationale behind the surgical technique and the clinical results of the iso-anatomical, single bundle bone patellar-tendon bone anterior cruciate ligament (ACL) reconstruction.
  
  
  METHODS
  Using a second incision on the distal lateral femur an outside-in femoral tunnel is drilled. Guided by a special aiming device it is possible to place the femoral tunnel in the centre of the ACL footprint in every single case.
  
  
  CONCLUSIONS
  Since every crucial step of the procedure is under visual control, the technique is safe and reliable, which is mirrored by good clinical results.
