4:1 Cutting Block Fixation
>
Locate the fixation pegs of the appropriate size
Express 4:1 Cutting Block into the pin holes created
on the distal femur .
Note: Check run-out of the anterior cut . If not enough
anterior bone is resected, consider selecting the next
smaller size 4:1 Cutting Block . Ideally, the cut should be
flush with the distal femur .
>
Pin the 4:1 Cutting Block in place for stability .
Femoral Anterior, Posterior and
Chamfer Cuts
>
Complete the remaining four femoral bone
resections .
>
The use of a .050˝ (1 .25mm) thick sawblade is
recommended .
>
The order of bone resections is not critical; however,
a recommended sequence for improved stability of
the 4:1 Cutting Block is:
1 . Anterior cortex .
2 . Posterior condyles .
3 . Posterior chamfer .
4 . Anterior chamfer .
Note:
• Cutting the anterior chamfer last helps stabilize the
cutting guide .
• It is advisable to pay close attention to minimizing
the bias on the sawblade during these resections .

Remove the 4:1 Cutting Block .
