How to use it
Set-up, use and care
- 1
Guide the residual limb into the socket until the condyles seat fully.
- 2
Confirm the knee's mechanical axis sits level with your sound knee.
- 3
Check the socket rim for pressure after the first hour of wear.
- 4
Return for a socket refit as the limb changes shape.
Description
A knee disarticulation socket holds the femur end and often needs no suspension strap, because the condyles carry the limb. It is paired with a polycentric or four-bar knee so the mechanical joint lines up with your own knee axis.
