Milling
Mount the patellar bushing onto the patellar
clamp with the ratchet.
Select the patellar reamer that will match the
patella size. Depending on the selected
anchoring technique, mill briefly (“onlay”
technique) or countersink by 3 to 5 mm
(“inlay” technique). Milling down to the stop
will produce a depth of 5 mm.
Important
Patellar implants 10 mm high are recom-
mended as standard. Implants with a height
of 8 mm are available as an alternative for
thin patellas.
Drill anchoring holes
Using the patellar drill guide and the patellar
drill with stop, prepare the anchoring holes
for the pegs.
Trial reduction
Patellar trials are available for trial reduction.
