Question 4
Question
What is the thickness of bone removed from the distal femur when implanting a Physica KR?
Question 5
Question
What does a bronze finish to a Physica KR instrument indicate to a scrub nurse or surgeon.
Answer
-
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
Question 6
Question
Why does the Physica KR have left and right tibial liner trials?
Answer
-
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

Answer
-
+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
Question 8
Question

Answer
-
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
Question 9
Question

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
Question 12
Question
Why does the tibial drill have options for 20mm, 40mm and 60mm depths?
Answer
-
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
