mako pka questions with accurate answers
after poses captured, surgeon can make adjustments where Ans✓✓✓ in
the sagittal view
bone registration points Ans✓✓✓ 40 femoral condyle
40 medial tibia
42 lateral tibia
bone registration purpose Ans✓✓✓ uses points from 3 planes to create
a point cloud of patients actual anatomy
the 3d model is then overlayed on top of the patients actual anatomy
burr size Ans✓✓✓ 6mm
burr workflow operative side Ans✓✓✓ can be on either side of patient
cartilage mapping points Ans✓✓✓ 17 points
-13 on PF ( 5 down deepest part of trochlear groove, 1 superior lateral
tip, 1 superior medial tip, 6 points near pink dots...one next to each of
the 4 pink dots and one in between)
-3 on femoral implant (1 most anterior part, 2 points lateral to that
anterior point)
-1 where cruciate ligaments are at bottom of PF
, cartilage mapping purpose Ans✓✓✓ ensure there is a smooth transition
for the patella to glide from the trochlear groove onto the femoral
implant
cartilage mapping tool Ans✓✓✓ green probe used
point captured along anterior tip of femoral implant
coronal view rotation Ans✓✓✓ varus/valgus
CT landmarks Ans✓✓✓ hip center
medial epicondyle
lateral epicondyle
femur knee center
medial malleolus
lateral malleolus
rotational landmark
tibia knee center
during joint balancing for each pose the surgeon: Ans✓✓✓ corrects
deformity by applying varus/valgus force to the joint
femur knee center landmark Ans✓✓✓ place in center of butterfly in
transverse view
this creates the distal end of the mechanical axis of the femur
