COMPLETE SOLUTIONS
◉ medial bicomp PF steps
Answer: 0) transverse view for size
1) superior lateral tip
2) trochlear groove
3) bloominsats line
4)superior medial tip
5) PF wings
6) PF to femoral implant space
◉ lateral uni tibia order
Answer: transverse
coronal
sagittal
◉ lateral uni femur order
Answer: 3D model
sagittal
coronal
◉ Medial bicomp PF step 0
, Answer: look at transverse view for size
make sure there is no overhang to the medial and lateral ridges
but also no more than 2mm inset to ridges
◉ Medial bicomp PF step 1
Answer: superior lateral tip
click pink dot in transverse view then look in sagittal view
pink dot is highlighted - you want the tip of the implant to be split
50/50 by native bone as best as possible
◉ Medial bicomp PF step 2
Answer: trochlear groove
click deepest part of groove in transverse view then look in
sagittal view
want implant to be 2mm proud of bone (measure with crosshair)
to adjust this you can anchor the superior lateral tip and add up to
5 degrees of flexion
◉ Medial bicomp PF step 3
Answer: bloominsats line - radiographic landmark where cruciate
ligaments originate
look in sagittal view to find bright white line on posterior side
make sure implant is anterior to line
◉ Medial bicomp PF step 4
