1.27mm
What pins are used to secure the femoral and tibial resection guides for Physica KR?
70mm headless pins
90mm headless pins
70mm headed pins
What pins are used to secure the tibial trial sizing template to the tibia?
Short headed pins
Long headed pins
What is the thickness of bone removed from the distal femur when implanting a Physica KR?
6.5mm
10mm
11mm
What does a bronze finish to a Physica KR instrument indicate to a scrub nurse or surgeon.
Indicate whether the instrument is used on the femur or the tibia
Indicate the instrument is high value and special compared to other knee system
Indicate the feature can be used to join different instruments or provide an opportunity to adjust the instrument in some manner
Why does the Physica KR have left and right tibial liner trials?
To take into account the peripheral shape of the tibia
To take into account the asymmetrical medial and lateral compartments of the KR design
Design in line with all other knee systems that also have left and right liner trials
Which holes are used to secure the distal cutting block to the femur, how to they differ to others found on the instrument?
+2mm holes, they are proximal to the neutral cut
-2mm holes, they are distal to the neutral cut
"0" holes which are identified by the addition of a chamfer recess
When sizing the femur - how do you know the stylus is fully inserted into the rotation guide
There is an audible click
A groove on the black shaft aligns with a groove in the rotation guide
Depth of insertion is not a critical facor
What are the depth options on the tibial stylus
10mm or 2mm
8mm or 2mm
2mm or 4mm
When completing a left Physica KR Knee, which tibial cutting guide is used
3 degrees symmetric
0 degrees symmetric
Left 3 degrees
Left 0 degrees
Which of the following is completed when completing final preparation of the Physica KR tibia
Assemble appropriate keel guide
Set drill assembly to "0" and drill the tibia until the depth stop
Assemble the appropriate winged punch to the impactor handle and impact fully
Drill 2 lug holes for the fixation pegs
Why does the tibial drill have options for 20mm, 40mm and 60mm depths?
The drill is taken from another Lima set and adapted for Physica KR
The drill can also be used for 20mm, 40mm and 60mm extension stems
Sometimes the surgeon may wish to drill further to increase the cement mantle
Which tray is the tibial keel impactor found in?
Tibial Preparation
Tibial Resection
Femoral Resections
When assembling the handle for the trial tibial plate, which side should the handle be inserted for a left knee.
Doesn't matter
Left side
Right side
Which instrument can be used if the surgeon needs to remove further bone/osteophytes from the posterior femur
Bone file
Oscillating saw
Curved Osteotome
How is the femoral type and size indicated on the trial components?
Etched on the front of the component
Raised detail on the rear of the anterior aspect of the component
The location within the instrument trays is used to confirm the size
Which tray is the femoral lug drill located?
Femoral resections tray
Femoral and tibia liner trials tray
Miscellaneous extras tray
What "up and downsizing" is permitted when using a Physica KR knee
Plus or Minus 1 size
Any size femur with any size tibia
Plus or Minus 2 sizes
Femur must match tibia
When are the magnetic posterior augments used on the Physica KR sizing guide?
Valgus knees
Varus knees
Knees where there is bone loss on the posterior aspect of the femur
In addition to tibia size and thickness, what additional check should be made when opening a Physica KR liner?
Ensure the component is the appropriate LEFT or RIGHT
Check if it is made of Vit E or X-Lima polyethylene
Check if it is X-Lima or Standard polyethylene
