Bench Alignment In Alignment Apparatus; Static Alignment Optimisation - Otto Bock Kenevo 3C60 Instructions For Use Manual

7.1.3 Bench alignment in alignment apparatus

INFORMATION
The alignment recommendations must be observed in order for the prosthesis to function correctly.
INFORMATION
Before beginning the alignment, the prosthesis must be put into alignment mode using the adjustment software.
Only in alignment mode is the knee joint automatically locked in the flexion direction to allow for static alignment to
be carried out correctly.
INFORMATION
The patient's gait pattern shall change as he/she becomes accustomed to the prosthesis.
Therefore it is recommended to complete the entire adjustment procedure again about two weeks after the initial
fitting.
A correct bench alignment (e.g. using the 743A200 PROS.A. Assembly alignment apparatus) ensures that the user
can benefit from all the advantages of the product. If the L.A.S.A.R. Assembly alignment apparatus (743L200) is
available, it can be used as well. The position of the residual limb must be taken into account when positioning the
socket connector. Plumb lines in the frontal and sagittal planes (drawn from the hip joint's centre of rotation and
marked during plaster cast taking and trial fitting of the check socket) will facilitate correct positioning of the lamin­
ation anchor or socket adapter.

7.1.4 Static alignment optimisation

Static alignment can be substantially improved using the L.A.S.A.R. Posture (743L100=*). In order to achieve
adequate safety while simultaneously providing easy swing phase initiation, please proceed with alignment as fol­
lows:

Position the middle of the foot (MF) approx. 30 mm/1.18 inch
anterior to the alignment reference line (A). This applies to all
foot components that are recommended for use with the product,
independently of the previous alignment specifications in the
instructions for use of those feet!
Noting the alignment recommendation of the foot component,
add 5 mm to the effective heel height (shoe heel height – sole
thickness in the forefoot area) and set the outward rotation of the
foot.
Place the alignment reference point (=knee axis) approx. 0-5
mm/0-0.19 inch anterior to the alignment reference line.
Take into account the knee-ground distance and outward rotation
of the knee (the adapter insert provides for a rotation of approx.
5°). Recommended sagittal positioning of the alignment refer­
ence point: 20 mm/0.79 inch above the medial tibial plateau.
Connect the foot and knee joint using a tube adapter. To do so,
tilt the joint in the correct position and set the required tube
length.
Mark the lateral centre of the socket with a centred, proximal dot
and a distal dot. Mark a line through both points from the edge to
the end of the socket.
Now position the socket such that the alignment reference line
passes through the proximal centre mark.
Adjust the socket flexion to 3° – 5°, but take the individual situ­
ation (e.g. hip joint contractures) and the ischial tuberosity-to-
ground distance into account.
Connect the socket and modular knee using adapters.
