How many MPKA CT 8
landmarks
implants displayed in what green
color
1. medial uni
available procedures in 2.lateral uni
PKA 3. PF
4. medial bicompartmental
1. sizing
3 steps for medial tibia
2. positioning
sizing
3. verification
tibia size default 5
tibial size constraints none
tibial p. slope 3-7 degrees
tibial proudness 2.5-3.5mm recommended
goal for tibial slope 1-2 degrees LESS than native anatomical slope
resection depth formula poly size - proudness = resection depth
proudness top of implant to native bone surface
, 1. no overhang A/P or M/L
optimal tibial sizing
2.does not intrude on tibial eminence (ACL insertion)
1. align w/ native curvature
optimal tibial positioning 2. place on cortical rim
3. do not seat on osteophyte
5 degrees int - 5 degrees ext
medial tibial int/ext
(transverse view)
0 - 1.5 degrees varus
medial tibia var/val
(coronal view)
medial femur sizing 1 up 1 down
constraints
5 degrees flexion - 5 degrees extension

medial femur var/val
(coronal view)
1mm proud of bone
medial femur flex/ext goal
(use crosshair to measure)
outer = 4mm
inner and outer diameter
