Assemble prosthesis with socket, pylon, ankle, foot, and shoe. Alignment
reference line is equal to the weight line.
• Establish a vertical pylon. This is necessary for proper knee function.
• Establish knee center height. Use the most proximal anterior axis as a
reference point.
• Establish appropriate socket angles. We recommend at least 5° of socket
flexion.
• Position the socket so that the alignment reference line bisects the lateral
wall of the socket and falls 0 - 5 mm anterior to the pivot axis.
• Establish correct limb length.
NOTE: If the weight line is too far anterior to the pivot axis, the knee may
require more effort to initiate knee flexion.
Premature knee flexion may result from a weight line position posterior to the
pivot axis center.
• Anterior pylon tilt may result in premature knee flexion.
• Posterior pylon tilt may make it difficult for the amputee to bend the knee.
