Static alignment

Setup length
With flexion, adduction and abduction
properly accommodated, set the limb length
10 mm longer than the sound side to allow for
compression and deflection of the foot & axial
shock springs during gait. This should be re-
assessed before the dynamic trial commences
and the length adjusted accordingly.
Build line
This should fall 10 mm anterior to the centre
of the pyramid (with heel height properly
accommodated). The socket should be
positioned accordingly.
Dynamic alignment
Coronal plane
Ensure that M-L thrust is minimal by adjusting
relative positions of socket and foot.
Saggital plane
Check for smooth transition from heel strike
to toe-off. Ensure also that when standing the
heel and toe are evenly loaded and that both
are touching the floor.
Trans-femoral alignment
Align trans-femoral components according
to fitting instructions supplied with the knee,
keeping the build line relative to this device,
as shown.
