This document provides instructions for setting up and using a navigation system for knee replacement surgery. It describes registering the femur and tibia, verifying alignment, and measuring resection heights. Key steps include positioning cutting blocks using instrumentation, placing reflective markers for registration, acquiring anatomical landmarks, checking alignment displays, and adjusting as needed. Manufacturer and copyright information is also provided.

1. ALIGNMENT
VERIFICATION
FEMUR SETUP
NOTE: Verification possibilities: femur first, tibia first, femur only, tibia only.
• Position the cutting block in the required position using standard (intramedullary)
instrumentation. Do not use more pins than required for preliminary fixation.
• Place the cutting block adapter in the saw blade slot, with the reflective marker
spheres facing the camera.
FEMORAL REGISTRATION
Perform femur registration by acquiring:
Femoral head center
Femoral mechanical axis
• Rotational references
•
•
NOTE: Pressing the Clip-On Remote Control for a long time repeats entire
registration.
ALIGNMENT VERIFICATION FEMUR
• Check the displayed information and if required, adjust the femoral cutting
block’s position and/or orientation.
• Repeat registration.
RESECTION HEIGHT MEASUREMENT FEMUR
• Place the pointer on the distal condyles to measure the distance to the cutting
slot as an indicator for the resection height.

2. ALIGNMENT
VERIFICATION
TIBIA SETUP
• Position the cutting block in the required position using standard (extramedullary)
instrumentation. Do not use more pins than required for preliminary fixation.
• Place the cutting block adapter in the saw blade slot, with the reflective marker
spheres facing the camera.
TIBIA REGISTRATION
Perform tibia registration by acquiring:
Malleolar points
Tibial mechanical axis
• AP direction
•
•
ALIGNMENT VERIFICATION TIBIA
• Check the displayed information and if required, adjust the tibial cutting block’s
position and/or orientation.
• Repeat registration.
RESECTION HEIGHT MEASUREMENT TIBIA
• Use the pointer to measure the distance from the tibial resection plane to the
cutting slot as an indicator for the resection height.
