Femoral Component Removal
In the event that the femoral implant needs to be
removed, Disrupt the femoral implant/bone interface
with flexible osteotomes or thin saw blades with an
oscillating saw. Once the prosthetic bone interface
is loosened, a femoral extraction tool may be used
to aid in removal of the femoral component from
the bone. Persona Revision Femurs have medial and
lateral notches to help facilitate removal of the femoral
component (Figure 3).

Stem Removal
In the event that a Persona Stem needs to be removed
from the tibial or femoral canals, the stem extractor
may be used to assist in removal. Remove any
residual cement around the stem junction. Thread
the stem extractor around the end of the stem in
the canal and lock into place (Figure 4). Assemble
the slap hammer to the end of the extractor in a
clockwise direction. Slap hammer out the stem
(Figure 5).
