Note: If maximum allowable load of 70 lbf is reached in either compartment, the VERASENSE device must be
removed from the knee joint and “re-zeroed” by holding VERASENSE with superior side (articulating surface)
facing the floor for three (3) seconds, Re-Zero enabled will appear on the VERASENSE Software Application,
followed by Re-Zero Complete indicating that VERASENSE has been reset to zero; or Re-Zero button from the
VERASENSE Software Application by Pressing the Re-Zero button.
a. Compartment Re-Zero allows for a re-zero of the device without removing it from the joint. With
VERASENSE in the joint, apply a varus or valgus thrust to the knee to off-load the desired medial or lateral
compartment. When the VERASENSE surface is visually unloaded, select the laterality indicator of the
unloaded side to initiate the Re-Zero. Wait for Re-Zero Enabled and Re-Zero Completed messages to
display. Repeat the steps on the opposite compartment to complete the Re-Zero.
Note: Compartment Re-Zero is only available with VERASENSE devices that communicate with the
LinkStation MINI via Bluetooth. Check label on the front of the sensor box for the Bluetooth symbol .
