10. PATELLA
Insert the patella resection guides into the patella clamp.
After carefully releasing the periphery of the patella,
position the resection guides at the appropriate resection
level, with the assistance of the patellar stylus assembled
in one slot of the resection guide. The stylus should be in
contact with the top of the patella dome allowing for a 10
mm fixed cut.
Then close the clamp handle until contact between the
resection guides and the patella bone is made and lock the
clamp with the button provided.

patella and drill the three holes using the patellar pegs drill.
Pressurize the trial resurfacing patella of the appropriate
size, reduce the patella and test the knee through its full
