• The angled elevator can also be used to remove residual
cement from the anterior aspect of the tibial tray, as
well as any cement from around the bone island.
eXPert Advice: Positioning the knee in about 15 degrees of
flexion should facilitate accessing the posterior aspect of the
tibial tray.
• Check that no cement has penetrated the locking
bar slot.
eXPert Advice: Cement should be completely removed
along the interface between the tibial component and
the bone island in order to allow proper engagement of the
tibial bearings.
Note:
• The tibial implant is packaged with a protective
covering in the tibial tray locking bar slot to protect it
from cement and debris. Be sure to remove this cover.
Tibial Tray Implantation
with Intact/Functioning ACL (cont.)
• After pressurization, all cement that remains proud
of the bone should be removed. A 1/2 inch (12.7 mm)
curved osteotome, positioned concave down, is useful
to scrape away excess cement.
• If there is significant blood or saline on the cement
surface, it can be carefully dried using an osteotome
wrapped in a clean, dry lap sponge prior to final
implant placement.
Note: While drying blood or saline, make sure not to
remove the cement that was just placed on to the surface.
• Insert the tibial component into the posterior keel slots
first, then settle the tibia into the anterior peg holes
second. This will help extrude the cement forward for
easier removal.
• Impact the tray with the tibial impactor (32-700364)
moving from posterior to anterior with impaction
(Figure 53).
