Patella Resection
(cont.)
Option 1: Surface Clamp
(cont.)
1-peg patellar component:
– Use the 1-peg patellar drill guide to locate the
placement of the central peg.
– Drill the central hole using the 5/16 inch Series
A™ Patellar Drill.
– Select a trial patellar component to optimize
coverage without increasing patellar thickness
beyond pre-resection height.
3-peg patellar component:
– Place the appropriately sized 3-peg drill guide
onto the resected patella and use the 1/4 inch
patellar drill to prepare for the component pegs
(Figure 5).
Option 2: Patella Milling
Tilt the patella for patella preparation.
Remove the osteophytes and peripatellar tissues down
to the level of the quadriceps and patellar tendon
insertion.
Determine the patella thickness and resection amount
by using the patella caliper.
Size the patella using the mill bushings (Figure 6).
Attach the size-specific bushing to the mill handle.
