When the…. ◦ The Extension Lateral live laxity value will decrease to 0mm ✓ The Extension Lateral Max value will decrease to 0.5mm ◦ The Extension Medial live laxity value will decrease to 0mm ◦ No mentioned answer choices ◦ All mentioned answer choices While "Trialing,' the user is limited to live 'Laxity Capture' only; this is due to the trials in the joint. ◦ T ✓ F The user can balance and modify the implant plan on the "Trialing' page. ◦ T ✓ F Consider the following scenario and included image: The user is capturing 'Hip Center', the following error will pop up if the spread metric used to calculate the Hip Center' fails more than once. Which of the following statement(s) apply: ◦ The captured "Hip Center is deleted when the user selects 'continue ◦ The captured 'Hip Center will impact the accuracy of the tibial bone registration ◦ The femoral checkpoint has moved ✓ The captured 'Hip Center remains unless the user deletes the landmark Consider the following scenario and included image: The user is capturing the tibia patient landmarks, and the following error popped up. The user selected 'Continue and decided to move forward with the captured landmarks. Which of the follow… ◦ The tibial array has been bumped ◦ Both mentioned answer choices ◦ No mentioned answer choices ✓ A warning will be displayed on the 'Bone Registration' page Consider the following scenario and included image: The user is capturing the tibia patient landmarks, and the following error will pop up on the failed attempt of tibia patient landmarks. ◦ Second ◦ Fourth ✓ First ◦ Third Consider the following scenario and included image: The user is capturing 'Hip Center', the following error will pop up if ◦ the spread metric used to calculate 'Hip Center fails more than once ◦ the pelvic array is used for intra-incisional tibia bone pin placement ◦ the femoral array drops out of camera view ✓ the spread metric used to calculate 'Hip Center fails once Consider the following scenario and included image. If the user presses the foot pedal or selects the 'Capture' button, which laxity value will be saved in this example? ◦ -4.0 ◦ 1.5 ✓ -2.0 mm ◦ -25 The user can switch between the plans but must lock the preferred plan before navigating to Initial Assessment', Tensioning', 'Bone preparation' and/or Trialing' pages. ✓ T ◦ F The 'Initial Assessment' capturable flexion range for flexion laxity poses is ◦ 85° to 95° ◦ dependent upon the native sagittal deformity flexion angle to ensure the capsule is lax during the extension pose captures ✓ 85° to 105° ◦ dependent upon the native coronal deformity flexion angle to ensure the capsule is lax during the extension pose captures Pre-resection laxity is calculated from the planned tibial resection to the planned femoral resection. ◦ T ✓ F planned articulating surface of femoral component and planing art. surf. Of the tibial component The laxity values displayed within TKA 2.0 represent ◦ the closest distance between the planned tibial resection to the planned articulating surface of the femoral component plus 8.5 mm ✓ No mentioned answer choices:…. closet distance between planned tibial resection and planned articulating surface of femoral component minus tibia component thickness ◦ the space between the planned articulating surface of the femoral component to the planned articulating surface of the tibial component ◦ the gaps between the planned femoral and tibial resections If the Mako System cuts deep to the implant plan, it will be displayed as red on the main window of the Bone Preparation' page. ◦ T ✓ F: yellow Which of the following warnings can be displayed on the 'Bone Preparation' page if triggered within Implant Planning'? ◦ Flange tip ◦ Combined flexion ✓ Notching ◦ Overhang If the implant plan has triggered the checkpoint near cut warning, the checkpoint will be displayed as yellow on the main window bone model while on all cuts. ◦ T ✓ F - yes will display on all cuts but only yellow for those cuts where the checkpoint will interact with the cutter Consider the following scenario: The surgeon has finished the tibial resection and would like to proceed to the posterior femur resection. Which checkpoints) will the surge ✓ Femur checkpoint only ◦ Cutter checkpoint (straight saw attachment) and femoral checkpoint ◦ Cutter checkpoint (straight saw attachment) only ◦ Cutter checkpoint (angled saw attachment) and femoral checkpoint Consider the following scenario: The surgeon has finished the tibial resection and would like to proceed to the posterior femur resection. Which checkpoints) will the surgeon user be required to pass? ✓ Femur checkpoint only ◦ Cutter checkpoint (straight saw attachment) and femoral checkpoint ◦ Cutter checkpoint (straight saw attachment) only ◦ Cutter checkpoint (angled saw attachment) and femoral checkpoint The 'To be cut' volume is displayed as blue on the 'Bone Preparation' page. ✓ T ◦ F Consider the following scenario: The surgeon has finished the anterior chamfer resection and would like to proceed to the distal femoral resection. Which checkpoints) will the surgeon user be required to pass ✓ Cutter checkpoint (angled saw attachment) only ◦ Cutter checkpoint (straight saw attachment) and femoral checkpoint ◦ Cutter checkpoint (straight saw attachment) only ◦ Cutter checkpoint (angled saw attachment) and femoral checkpoint Consider the following scenario: The surgeon user would like to cut the anterior femur first. The straight saw attachment cutter checkpoint has passed; however, the software is on the tibia dropdown. How will ✓ The software will detect the probe is within the femoral checkpoint and will verify the validity of the checkpoint, if a passing/green result is achieved the surgeon user will be granted access to the 'Anterior' cut ◦ No mentioned answer choices ◦ The software will detect the probe is within the femoral checkpoint, a pop-up will remind the user to select the Femur dropdown
