After drilling the two anterior pins, the TRUMATCH
Solutions Drill Guides are removed by twisting in a
counter-clockwise direction, while leaving the two
anterior pins in place (Figure 7). Remove the tibial pin
guide by moving it up and pulling it away from the
anterior fixation pins. Check to verify that the spikes of
the fixed reference guide are in the middle holes of the
bottom hole cluster. It is possible to position the spike
through the top hole and opposite bottom hole (vice-
versa). This will result in an incorrect rotation placement
of the cutting block.
Slide the appropriate L/R 0 degree HP Proximal Tibial
Cutting Block over the anterior fixation pins through the
“0” mm holes marked with a square. (Figure 8) If desired,
confirm the cut orientation with the angel wing. If
necessary, the block may be shifted 2 mm proximally or
distally by selecting the appropriate offset holes adjacent
to the “0”mm hole. Perform the proximal resection with
a 1.19 mm whale tail saw blade.
Remove the HP tibial cutting block and make sure bone
cuts are clean and void of any under-cut bone fragments.
Note:
The arthritic disease process can cause
adaptive bone changes that result in hard, sclerotic
bone in the affected tibial condyle, thus making
resection difficult. A solution is to start the tibial
cut on the “least affected” or the side opposite to the
more involved tibial condyle. This will provide an
easier entry cut in the intended orientation and sets
the path for the continued saw blade sweep through
the hard, sclerotic bone of the involved plateau.
