Cement Technique
Metal-backed tibial component
Engage the rounded end of the tibial trial of
appropriate size and thickness with the tibial
tray. Apply a layer of cement to the backside of
the tray.
Stabilising the trial and tray with a finger,
introduce the tibial prosthesis at a 45° angle,
engaging the most posterior aspect of the tibial
keel to the prepared channel first (Figure 38).
Lower the anterior of the prosthesis into position.
This sequence promotes the flow of cement from
posterior to anterior as the prosthesis is seated.
Use a mallet and the C–arm to complete the tibial
insertion (Figure 39).
Figure 38
Clear residual cement with a sponge or cement
removal tool such as a bent arthroscopy probe or
nerve hook. Pay particular attention to the rim of
the tibial tray.
It is essential to remove all residual cement to
prevent third body wear.
If a sponge was used posteriorly, remove
the sponge.
