Tibial Preparation
Tibial Resection with Intact/
Functional ACL (cont.)
Vertical Resection
• Remove the tibial resection spacer.
• After the horizontal resection level is set, place one 1/8"
quick release drill pin in the middle hole of one side of
the tibial universal cutting block and another one on
the opposite side (32-467619) (Figure 26).
• Insert the tibial vertical resection block captured
(32-700387) or un-captured (32-700034) in the slot of
the universal cutting block (Figure 27).
• Insert the tibial alignment guide (32-700384/385)
through the vertical resection block and island
outline. Use the ACL, femoral notch and tibial tubercle
landmarks to assist in determining rotation.
• If desired, place an alignment rod in the end of the
tibial alignment guide to verify tibial rotation.
eXPert Advice: To allow for larger tibial tray sizing, the
vertical cuts should be as far lateral as possible without
cutting the ACL.
Note:
• If the tibial component is downsized intraoperatively
from an 87 mm to an 83 mm size, the tibial bone island
will have to be recut to the appropriate size.
• Lock the vertical resection block by lifting the lever
into its upright position and pinning the block in place
using two headless threaded pins (32-700379).
• With a reciprocating saw blade, cut down to the
threaded pins; the pins will act as a saw stop. Ensure
the vertical resection extends from the anterior cortex
through the posterior cortex (Figure 28).
eXPert Advice: To prevent the reciprocating blade from
skiving, advance the blade in small increments, raising the
tip first and resecting downward.
