B. Aligning
Static alignment:
In the sagittal plane, the load line passes through the greater trochanter and between 0 and 5 mm in front of the axis of the knee.
Ensure that any flexion contracture in the patient is accommodated.
Align the foot in compliance with the manufacturer's instructions.
In the frontal plane, the load line passes through the middle of the socket, through the middle of the knee and between the
first and second toes.
Dynamic alignment:
Advancing the knee reduces the stability of the assembly and facilitates the initiation of the swing phase when walking.
Retracting the knee increases the stability and the feeling of safety for the patient when walking, but makes it more difficult
to initiate flexion.
The positioning of the connector on the socket is important. If necessary, use a translating adapter to try out different position
when determining the optimum alignment.
The threaded M36×1.5 adapter for the KD version does not accommodate any alignment adjustment. The socket must
therefore be made accordingly.
Check the alignment using suitable equipment (line laser, plumb line, etc.)
