tures) must be taken into account and, if necessary, more flexion should be provided. Also pay attention to the
ischial tuberosity to ground distance (Fig. 4).
Error during alignment of the prosthesis. Errors during the alignment of the prosthesis can lead
CAUTION
to malfunction and insufficient fitting results of the joint up to loss of function due to structural failure. This can
cause the patient to fall.
If the residual limb flexion is not taken into account, the joint will be positioned too far to the front.
• Connect the socket and modular knee joint using a corresponding adapter (e.g. 4R111, 4R41 Socket Adapter,
etc.). For alignment correction, use the 4R112 Sliding Adapter (only for temporary use!). When using socket
adapters with a 4-hole connection (e.g. 5R1=*, 5R6=*), the 4R118 Sliding Adapter can be used for a perma-
nent, additional posterior placement of 10 – 25 mm.

anchor is not provided. This puts too much strain on the screwed connection adapter and may cause damage
and subsequently cause the patient to fall. The rotation adjustment must not be used for length adjustment.
Screw in the thread adapter as far as possible and clamp with the cap screw. In case of the 4R43 Lamination
Anchor with threaded connector, position the clamp laterally or medially. In case of the 4R111=N Lamina-
tion Anchor with threaded connector, the anchor arms must be positioned in the anterior/posterior and me-
dial/lateral directions. Here, the clamp must be positioned to show in the anterior/medial or anterior/lateral
direction.
• Confirm the bench alignment and all measurements.

2.2.1 Checking the Socket after Bench Alignment

CAUTION
Error during alignment of the prosthesis. If the socket drain or air expulsion hole is incorrectly positioned,
the draining sweat may drop into the electric connector and lead to short-circuits in the electronics and malfunc-
tion of the knee joint which may subsequently cause the patient to fall.
Make sure the socket drain or air expulsion hole is not positioned frontally above the electric connector. Position
the hole on the side or back of the socket.

Error during alignment of the prosthesis.
CAUTION
Errors during the alignment of the prosthesis can dam-
age the hydraulic unit of the joint. A defective hydraulic
unit can lead to malfunction of the joint up to loss of
function due to structural failure. This can cause the
patient to fall.
The hydraulic unit may become damaged by contact
with the socket! At maximum flexion and insofar as
contact with the frame of the C-Leg cannot be avoided
(in case of voluminous residual limbs), the socket must
5 lie flat on the frame. Soft cushioning at the socket will
assist in maintaining the socket flat. At maximum flexion,
it is essential that the minimum distance of 3 mm (
maintained between the hydraulic unit and the socket.
Error during alignment of the prosthesis.
CAUTION
Errors during the alignment of the prosthesis can dam-
age the electronics of the joint. Defective electronics
can lead to malfunction of the joint. This can cause the
patient to fall.
The electronic unit may become damaged by contact
with the socket! At maximum extension (reached under
full capacity load!) the minimum distance of 5 mm (1/5")
must be maintained between the electronic unit and the
socket at the beginning of the dampening phase.
