Center the Ring at the highest position of the patella and clamp the patella for fixation. Place a Patellar Drill Depth Sleeve 39 on the clamp ring. Direct the Patellar Reamer 40 downwards into the Ring, with its tip touching the highest point of patellar. Place Patellar Reamer Stopper 41 level on the sleeve and tighten the stopper with a Screw Driver 42 . Then make sure that the drill depth of the reamer equals that of the patellar component thickness. Remove the sleeve and insert a Patellar Drill Guide 43 of the same size. Next, use the Patellar Drill 44 to create the pilot hole for the patellar component. Once the drilling is completed, the Patellar Reamer 40 is reintroduced into the Patellar Clamp Ring 37 for creating the inset patellar bed. NOTE: If the thickness of patella is smaller than 20 mm, it will be necessary to adjust the stopper manually to the desired drill depth to retain at least 8 mm patellar thickness. D.
