Deviations in the course of the load lines in 3D
mode
• Force transmission points far away from each other
• Significantly tilted towards each other at the top
Possible causes
• 1a), 2a), 3a)
• TF prostheses: pes equinus position for knee stabil­
isation
• Orthosis: spasm
Possible solutions
– 1b), 2b), 3b)
– Orthosis: use suitable means to establish
ground contact of the elevated heel to make
force transmission more balanced
Deviations in the course of the load lines in 3D
mode
• Force transmission points close together
• Significantly tilted away from each other at the top
Possible causes
• Hips not parallel to frontal plane
• 1a), 2a)
• Subjective instability of the prosthetic knee joint
• Unfavourable component selection
• Changes on the contralateral side
• Excessive compensation for a hip flexion contrac­
ture
• Unfavourable load application to the prosthetic
socket
Possible solutions
– 1b), 2b)
– Use a prosthetic knee joint with stance phase
support
– Take hip flexion contracture into account for
optimisation during the dynamic trial fitting
– Evenly distribute load application to the pros­
thetic socket
