Revision Knee System
Surgical Technique
Note: If a Trabecular Metal Tibial Cone is required,
proceed to Appendix B: Tibial Central Cone
Preparation section on page 50. To prepare the tibia
for a perimeter cone, reference the Persona Revision
Large Defect Surgical Technique 2723.1-GLBL-en
for surgical steps.
Remove all provisional components from the tibial
canal. If the construct is difficult to remove or cannot
be removed by hand, use the slap hammer to retrieve.
Keel Preparation
Attach the appropriately sized keel broach to the DR
handle by pulling back the lever on the handle and
rotating until locked (Figure 31).
Place the tibial keel broach over the stem extension
post and align with the marks made on the tibial
plateau previously for the keel fins (Figure 32). Impact
the tibial keel broach using a mallet (Figure 33). The
broach is fully seated when the top of the fins are level
with the tibia plateau.
Note: Silver keel broaches are only used for fixed
keel provisionals (not kitted).
Note: If two tibial augments are being utilized to
build up the construct, the top of the broach should
be level with where the anticipated tibial baseplate
will sit.
Note: The 0, +5 and +10 marks on the DR handle are
for femoral use only.
