MAKO PKA ACTUAL TEST PAPER 2026
COMPLETE QUESTIONS AND CORRECT
ANSWERS VERIFIED A+
●● How should initial posterior slope be positioned?
Answer: set crosshair in sagital view to mid-point of the tibia and drop
the crosshair slope 1-2 degrees below the native anatomic slope
●● what is the difference between pka and tka?
Answer: PKA is not a joint replacement procedure it is a joint
resurfacing procedure
●● How is adjusting implant proudness?
Answer: Moves the implant perpendicular to the posterior slope
●● Pre-planning guidelines for proudness?
Answer: 2.5-3.5 mm
●● Resection depth for tibia?
Answer: Poly size- proudness= resection depth for of the tibia
●● How to size tibial implant?
, Answer: Go to transverse view and move tibia implant to correct
location and toggle different sizes to determine best fit
●● How to determine correct tibia size?
Answer: No overhang A/P or M/L and does not intrube the tibial
intercondylar eminence (location of the ACL insertion)
●● recommended pre-operative planning for tibia IR/ER
Answer: IR/ER is 5 internal-5 external
●● in coronal view what are preoperative parameters for varus/valgus?
Answer: 0-1.5 varus
*want the implant to match the native curvature in the anterior and
posterior portions
●● medial femur implant sizing
Answer: 1) drag the implant to match the native condyle in the center of
the medial femoral condyle
2) in the sagital view drag the femoral component to match the curvature
of the native condyle
●● femoral preoperative IR/ER
Answer: 5 internal- 5 external
