Tibial Bearings and
Locking Bar Implantations
• Remove the tibial bearings and select the appropriate
Vanguard XP tibial bearings and insert onto the tibial tray
(Figure 58).
• Push posteriorly as far as possible using finger pressure.
eXPert Advice: The bearings must be flat on the baseplate
in all directions. If not, the locking bar will not insert.
Patellar Component Implantation
• Pulse lavage and dry patella.
• With the knee in full extension, apply a 2 to 3 mm thick
layer of cement onto the appropriate patellar component.
• Place component into the patella.
• Push into position with finger pressure so the peg(s)
engage(s) the prepared hole(s).
• Position the patellar clamp onto the component and
tighten the handle until the clamp head contacts
the component.
• Clamp tightly to compress the implant.
• Remove extruded cement in a routine manner.
• The clamp should be left in position and the knee in
extension until cement hardens (Figure 57).
