The femoral resection landmarks are defined by the hip center, femur knee center,
medial epicondyle and lateral epicondyle.
- True
- False - answerTrue

When Resection Landmarks cannot be successfully mapped to the bone model, a

, Suppose the surgeon intends to place the tibial bone pins intra-incision. In that case, the
user must select the 'Tibia intra-incisional pin placement' preferences. This will enable a
warning on the 'Trialing' page reminding the user to remove tibia intra-incision pins
before keel punch or stem ream.
- True
