Anterior placement, middle of the prosthetic foot to the alignment reference
line: 10 mm to 15 mm
   
Connect the prosthetic foot and prosthetic socket using the chosen adapters.
The instructions for use of the adapters must be observed.
   
Determine the centre of the prosthetic socket with the 50:50 gauge. Align the
prosthetic socket centrally to the alignment reference line.
Socket flexion: individual residual limb flexion +  5°
Frontal plane
Alignment reference line of prosthetic foot: between big toe and second
   
toe
Alignment reference line of prosthetic socket: along the lateral patella
edge
   
Observe the abduction or adduction position.

► Observe the information in the prosthetic knee joint instructions for use.

5.2.2 Static Alignment

Ottobock recommends checking the alignment of the prosthesis using
the L.A.S.A.R. Posture and adapting it as needed.
If necessary, the alignment recommendations (TF modular leg pros­
theses: 646F219*, TT modular leg prostheses: 646F336*) may be
requested from Ottobock.

5.2.3 Dynamic Trial Fitting

Adapt the alignment of the prosthesis in the frontal plane and the sagittal
plane (e.g. by making angle or slide adjustments) to ensure an optimum
gait pattern.
TT fittings:Make sure that physiological knee movement in the sagittal
and frontal plane is achieved when the leg begins to bear weight after
the heel strike. Avoid medial movement of the knee joint. If the knee joint
moves in the medial direction in the first half of the stance phase, move
the prosthetic foot in the medial direction. If the medial movement occurs
in the second half of the stance phase, reduce the exterior rotation of the
prosthetic foot.
5.3 Installing the ankle block (exoskeletal design)
Required materials: Screw connection (see Page 13), 710D4 torque
>
wrench, sandpaper (grain size 40), 636W28 Ottobock special adhesive
and hardener, suitable solvent (e.g. 634A28)
1) Insert the threaded socket of the screw connection in the proximal side
of the hole in the ankle block.
