Resect Distal Femur
Attach the 0 degrees captured/uncaptured
cutting head to the distal femoral resection guide
(Figure 134). The adjustment dial on the resection
guide can be set from “-2” to “+4”. The “0” represents
a 10 mm distal resection (Figure 135). The -1 setting
represents a 9 mm resection while the +4 setting
represents a 14 mm resection. Upon rotation, the dial
has palpable stops and clear markings at each 2 mm
location. One half rotation creates 1 mm of adjustment.
Insert the distal femoral resection guide with the
cutting head into the femoral valgus alignment guide
until the cutting head rests on the anterior femoral
cortex.

(cont.)
Verify the desired resection setting on the distal
femoral resection guide and/or rotate the adjustment
dial to attain the desired setting (Figure 136a). Insert
trocar tipped pins through the two standard pin holes
marked “0” on the anterior surface of the cutting head
(Figure 136b). Additional 2 mm adjustments may be
made by removing the cutting head from the pins
and replacing the cutting head on the pins in the sets
of holes marked -2, +2, and +4. The markings on the
cutting head indicate, in millimeters, the amount of
bone resection each will yield relative to the initial
distal resection setting.
