Select the 4in1 block which corresponds to the size
previously determined. Slide the 4in1 block over the pins
through the corresponding row of parallel positioning holes
until it contacts the distal resection.
Check the level of the anterior cut by placing the angel wing
into the slot of the anterior resection.
Once the position of the 4in1 block is satisfactory, secure
the cutting block by inserting two headed pins into the two
lateral oblique fixation holes. Remove the positioning pins.
OPTION
If no correction washers were used, cancellous bone
screws can be used alternatively or together with the lateral
pins to stabilize the 4in1 guide. Insert the cancellous bone
screws through the dedicated holes using the dedicated
screwdriver.

CAUTION
It is strongly recommended not to impact or hammer the
4in1 guide with a mallet. If the surgeon considers such
action necessary, do not impact directly on the 4in1 guide.
Use the femoral impactor as shown in the picture below.
