WITH ANSWERS GRADED A+
• varus/valgus parameters medial femur -✓✓ 3 degrees varus
3 degrees valgus
• flexion/extension parameters medial femur -✓✓ 5 degrees flexion
5 degrees extension
• internal/external parameters medial tibia -✓✓ 5 degrees internal
5 degrees external
• varus parameters medial tibia -✓✓ 0- 1.5 degrees varus
• posterior slope parameters medial tibia -✓✓ 3-7 degrees
• internal/external parameters PF -✓✓ 4 degrees internal
0 degrees external
• varus/valgus parameters PF -✓✓ 3 degrees varus
2 degrees valgus
• flexion/extension parameters PF -✓✓ 5 degrees flexion
5 degrees extension
• internal/external parameters lateral femur -✓✓ 5 degrees internal
5 degrees external
• varus/valgus parameters lateral femur -✓✓ 3 degrees varus
3 degrees valgus
• flexion/extension parameters lateral femur -✓✓ 5 degrees flexion
5 degrees extension
• internal/external parameters lateral tibia -✓✓ 10 degrees internal
5 degrees external
• valgus parameters lateral tibia -✓✓ 0 -1.5 degrees valgus
• posterior slope lateral tibia -✓✓ 0-7 degrees posterior slope
• transverse view rotation -✓✓ internal/ external
, • coronal view rotation -✓✓ varus/valgus
• sagittal view rotation tibia -✓✓ posterior slope
• sagittal view rotation femur/pf -✓✓ flexion/extension
• CT landmarks -✓✓ hip center
medial epicondyle
lateral epicondyle
femur knee center
medial malleolus
lateral malleolus
rotational landmark
tibia knee center
• Hip center landmark -✓✓ center of femoral head, best in coronal
established the proximal end of the mechanical axis of the femur
• medial epicondyle landmark -✓✓ medial sulcus, best in transverse view
this and the lateral epicondyle create the sTEA
• lateral epicondyle landmark -✓✓ most prominent lateral point, best in transverse view
this with the medial epicondyle create sTEA
• femur knee center landmark -✓✓ place in center of butterfly in transverse view
this creates the distal end of the mechanical axis of the femur
• medial malleolus landmark -✓✓ most prominent point medially, best in coronal
this+ hip center + lateral malleolus create mechanical axis of the leg
• lateral malleolus landmark -✓✓ most prominent point laterally, coronal view
this + hip center + medial malleolus create mechanical axis of the leg
• rotational landmark -✓✓ in transverse view:
find PCL footprint and place blue dot here
scroll until you see tubercle
adjust top arrow so it is to the medial third of the tubercle
this gives you the a/p m/l axis of tibia
• tibia knee center -✓✓ coronal view- top center point
gives you proximal end of tibia mechanical axis
• when checking rotational landmark in implant planning if there is too much space on
lateral side: -✓✓ move rotational landmark arrow medially
