The intent was to drill the femoral tunnel anatomically in all cases. In group A the femoral tunnel was drilled arthroscopically with an offset aimer. In group B the femoral tunnel was drilled arthroscopically with the BullsEye guide. Two tunnels were drilled through the same entry point in each knee. One was done at 110\u00b0 of knee flexion and the other at 130\u00b0. They were scanned by computed tomography and reconstructed 3\u2010dimensionally. Volume\u2010rendering software was used to document relations of the drilled tunnel to the bony anatomy and tunnel length.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In group B the femoral tunnel was placed at the center of the femoral insertion site. The center of the tunnel was 9.4 mm from the high cartilage margin and 8.6 mm from the low cartilage margin. In group A the tunnels were placed deeper (5.4 mm and 12.6 mm, respectively) (\n                      <jats:italic>P<\/jats:italic>\n                      = .018). There were no differences in tunnel length for either knee flexion degree. Three of the tunnels drilled at 110\u00b0 in group A compromised the posterior tunnel wall and measured less than 25 mm in length.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Accurate placement in the center of the femoral footprint of the ACL is better accomplished with the BullsEye guide rather than 5\u2010mm offset aimers. Five\u2010millimeter offset aimers might cause posterior tunnel blowout and present the risk of obtaining short tunnels when performing oblique femoral tunnel placement through the anteromedial portal
