Item see fig. 4
Required tools and materials:
743A80 50:50 Gauge, alignment apparatus (e.g., 743L200
L.A.S.A.R. Assembly or 743A200 PROS.A. Assembly)
Prosthetic knee joint, locked (note the section "Use" – see
Page 29)
a–p positioning of the prosthetic foot alignment reference point to
the alignment reference line:
+40 mm (beginner) to 0 mm (advanced)
Exterior foot rotation:
approx. 5°
Structural height of the prosthetic knee joint at the alignment refer­
ence point (rotation axis of the prosthetic knee joint):
MTP-floor measurement + 20 mm
a–p positioning of the alignment reference point to the alignment
reference line:
0 mm
Exterior rotation of the prosthetic knee joint:
approx. 5°
Join the prosthetic foot and the prosthetic knee joint with the help
of the foot adapter (for TF trial prosthesis: 4R206; for TF sport
prosthesis: 4R204) and the socket adapter.
The socket adapter can be positioned on the foot adapter in three
positions in the a-p direction. The exterior anterior position is
recommended for advanced users, the exterior posterior position
for beginners.
Observe the adapter instructions for use during adaptation and
installation.
Additional adapters (double adapter, socket adapter) can also be
used for height adjustment (see the section "Combination Possibil­
ities" – see Page 20).
Mark 2 centre points laterally on the prosthetic socket:
