User Guide | Guardian Mechanical Knee
Thank you for using College Park’s Guardian Knee!
Your prosthetist will instruct you on the proper use of the
knee. If you do not understand the knee or have any questions
about using it, please ask your prosthetist.
USING THE GUARDIAN KNEE
The Guardian knee has two functional modes. Before you begin using the knee, your
prosthetist will determine the setting that is most appropriate for you and will activate
that mode.
Stance Control Mode - Knee operates normally
Locking Mode - - Knee will not flex until the manual lock lever is pulled
USING THE MANUAL LOCK FEATURE
If the locking mode has been activated, there will be a manual lever attached to your
prosthesis so you can control when it should be locked or unlocked.
Locked Position
Standing/Walking:
The knee will not flex
Lock Release
To Sit Down:
Pull upward on the manual
lever while shifting your
weight forward slightly. This
allows the knee to flex.
Releasing the lever will
return it to the locked
position.
Temporary Unlock
Deactivates the lock
function temporarily:
The knee will remain
unlocked when the lever is in
this position and will operate
in stance control mode.
Note: Temporary Unlock will
only be possible if the proper
adjustments have been made
by your prosthetist!
