What is the purpose of resection landmarks?
Resection landmarks serve as reference points for calculating bone resection values.
Which bones have resection landmarks for medial and lateral resection thicknesses?
Distal femur, posterior femur, and proximal tibia.
How are resection landmarks populated on bone models?
They are populated based on an algorithm using selected CT landmarks.
What is the most distal point of the distal medial condyle of the femur called?
Femur distal medial.
What is the most distal point of the distal lateral condyle of the femur called?
Femur distal lateral.
What is the purpose of CT landmarks in relation to the femur?
CT landmarks define the femur coordinate system and the default position of femoral
resection landmarks.
What are the key CT landmarks that define the femur resection landmarks?
Hip center, femur knee center, medial epicondyle, lateral epicondyle.
What happens if the femur coordinate system changes?
The femur resection landmarks are re-computed, overwriting previous positions.
What are the CT landmarks that define the tibia coordinate system?
Medial malleolus, lateral malleolus, tibia knee center, rotational landmark.
What should be avoided when selecting resection landmarks?
,Locations on osteophytes, bony deformities, and the outer edges of the bone.
How should the distal femur resection landmark be positioned?
On the most distal face of the femoral bone model, avoiding anterior regions and outer
edges.
What is the significance of the posterior femur resection landmarks?
They are used to calculate the posterior condylar axis (PCA).
Where should the proximal tibia resection landmarks be positioned?
Approximately 2/3 posterior from the anterior tibia, near the lateral plateau.
What should the user verify regarding CT landmarks and resection landmarks?
The user must verify the position of both CT landmarks and resection landmarks.
What occurs if the application cannot compute the femur resection landmarks?
A pop-up will advise the user, and all femur CT landmarks will be cleared.
What is the recommended action if the default resection landmarks appear incorrect?
They can be modified by manually selecting the correct point.
What visual cue indicates that a resection landmark is selected for editing?
The sphere will display as blue.
What should be the focus when selecting the posterior femur resection landmark?
Centralize the landmark on the posterior condyle and avoid outer edges.
How can resection landmarks be thought of in terms of functionality?
As 'virtual cutting blocks' used to measure condyle resection thicknesses.
What are constitutional landmarks?
Constitutional landmarks are fixed points used to compute alignment values and are not
editable.
How are femur constitutional landmarks determined?
They are computed using the hip center, femur knee center, medial epicondyle, and lateral
epicondyle.
,What points are used to compute tibia constitutional landmarks?
Tibia constitutional landmarks are computed using the tibia knee center, rotational
landmark, medial malleolus, and lateral malleolus.
What is the preferred alignment theory in implant planning?
The preferred alignment theory is mechanical alignment, while constitutional alignment
should be disabled.
What is LDFA in the context of constitutional alignment?
LDFA stands for lateral distal femoral angle, calculated using femur distal medial and femur
distal lateral constitutional landmarks.
What does MPTA stand for?
MPTA stands for medial proximal tibial angle, calculated using tibial constitutional
landmarks.
What is the maximum number of capture points that can be mapped per bone?
The maximum number of capture points that can be mapped is 100 per bone.
What happens if the maximum number of capture points is reached?
An information pop-up will advise 'Collected points > 100'.
How can mapped points be hidden in the application?
Mapped points can be hidden by disabling 'Landmarks View'.
What does the control panel allow the user to do?
The control panel allows the user to select preferred implant systems and compatible
components.
What happens if incompatible implant components are selected?
The application is designed to automatically deselect incompatible choices.
How many unique implant plans can be saved within a session file?
Up to 8 unique implant plans can be saved within a session file.
What is the function of the 'Capture Points' feature?
, The 'Capture Points' feature is used to plot points on the virtual model with a probe
intraoperatively.
What is the significance of the 'Planned varus' in limb view?
'Planned varus' represents the planned overall coronal limb alignment based on the current
plan.
What does the deformity table populate with?
The deformity table populates pose capture information once captured intraoperatively.
What is the purpose of the Stryker representative's discussion with a surgeon?
The Stryker representative discusses constitutional alignment only if the surgeon inquires
about it.
What is the main purpose of incorporating constitutional alignment into the
software?
The main purpose is for clinical research and internal R&D purposes.
What is the femur distal medial landmark?
The femur distal medial is the most distal point of the medial condyle.
What is the tibia proximal lateral landmark?
The tibia proximal lateral is approximately 2/3 posterior from the anterior tibia.
What does the term 'patch landmark' refer to?
Patch landmark is the calculated centroid of 20 patch points dispersed about the proximal
medial and lateral tibial plateau.
What is the relationship between femur component varus/valgus and tibia component
varus/valgus?
Overall limb alignment is the sum of femur component varus/valgus and tibia component
varus/valgus.
What happens when a session file contains one plan?
The plan will auto-lock.
What does the 'Toolbar: Implant View' do?
It toggles the display of the implant models in all 3D views.
