After resecting the proximal tibia, bring
the knee to full extension. Insert the
8mm Spacer Block into the joint space
until the anterior stop contacts the
anterior tibia (Fig. 1). The Spacer Block
must be fully inserted and sit flat on
the resected tibial surface to ensure
that the proper amount of femoral
bone will be resected.
If the 8mm Spacer Block will not fit into
the joint, remove an additional 2mm
from the proximal tibia. If the 8mm
Spacer Block is too loose, use a thicker
Spacer Block.
Insert a 48mm Headed Screw or
predrill and insert a Short-head
Holding Pin into the anteromedial
angled hole in the Spacer Block (Fig. 2).
Attach the Alignment Tower to the
Spacer Block (Fig. 3) and insert the
Alignment Rod through the Alignment
Tower. Then insert the Targeting Guide
onto the Alignment Rod, and position
the guide relative to the femoral head
to check alignment (Fig. 4).
