           - tibial tunnel is created prior to femoral tunnel; br/>
           - a more medial to lateral tunnel placement, will cause the a more medial to lateral femoral tunnel; br/>
           - femoral tunnel must be oriented in a somewhat lateral direction, in order to have the guide wire to exit distal to tourniquet; br/>
    - strong>preparation - femoral tunnel:/strong> br/>
           - knee joint is flexed to at least 90 deg, which opens up the notch; br/>
           - in saggital plane, guide wire should pierce roof of the inter-condylar notch at a point about 6 mm anterior to posterior edge; br/>
           - 6 mm offset guide is useful to achieve a precise measurement; br/>
           - in axial plane, the guide wire should pierce notch at 1 to 2 O'clock position (left knee) or the 10-11 O'clock position (right knee); br/>
           - if tibial tunnel does not allow easy access to posterior aspect of intercondylar notch, additional knee flexion will move guide wire posteriorly; br/>

   - strong>reaming:/strong> br/>
           - a cannulated dill (10 mm) is placed over the guide wire and is reamed initially to a depth of 4-5 mm; br/>
           - drill is backed out, and the foot print is examined for possible "blow out" of the back wall br/>
           - note that geometry of posterior cortex is in MD's favor, hence if there is doubt about the back wall, surgeon can ream several br/>
                  millimeters further and then reassess the situation; br/>
           - cannulated reamer is then reamed to a depth of about 30 to 35 mm: br/>
