For each knee, three virtual 7\u2010mm\u2010diameter femoral tunnels were created. One of the tunnels used an anatomic fixation landmark (anatomic fixation), while the other two used established radiologic methods. We calculated the percentage of the anatomic tunnel covered by the tunnel created according to the method described by Schoettle, and the percentage of the anatomic tunnel covered by the tunnel created according to the method described by Stephen. These percentages were compared using paired Student's <jats:italic>t<\/jats:italic> test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The percentage of anatomic tunnel area covered by the femoral tunnel created using Schoettle's method was 36.7 \u00b1 25.2 %.
