Össur TOTAL KNEE JUNIOR Instrucciones Para El Uso página 6

Adapters from other manufacturer may not fully engage all threads. They
may compromise strength and void the warranty. Never tighten adapters
against the head.
When prong adapters are used, resin may get under the adapter and
hinder full thread engagement. Carefully remove resin without damaging
the adapter so that adapter threads can be fully engaged when mounted
on the knee.
Important: Contact between socket/adapter and proximal 2/3 of back link
must be avoided when fully flexing knee (Figure 4). Contact in this area
can damage knee and void the warranty. Contact between socket and
back link below balance unit is acceptable.
If pylon is too short for changed setup, do not compensate by putting a
spacer into the knee tube adapter as this may compromise strength and
void the warranty (Figure 5). Use a new Össur pylon cut to correct length
for maximum patient safety.
BENCH ALIGNMENT (Figure 2)
• Assemble prosthetic foot, pylon and knee.
• Establish knee centre height, measured from the knee center
reference(3). Tighten tube clamp to 8 Nm(6 ft-lbs) (Figure 6)
• Place appropriate heel height under heel or fit patient's shoe.
• Establish vertical pylon for proper knee function. Alignment reference
line (1) from pivot axis (6) should pass through posterior 1/3 mark on
Flex-Foot
®
• Attach socket with selected adapter combination to knee. Tighten to
torque as specified in adapter IFU. Ensure flexion/extension and
abduction/adduction angles are as determined in patient assessment.
Alignment reference line (1) from bisection of socket on ischial level
(2) should pass through pivot axis (6) of knee and posterior 1/3 mark
on Flex-Foot cover.
• Make sure total length of prosthesis is correct.
NOTE: If alignment reference line (1) is too far anterior to pivot axis(6),
more effort may be required to initiate knee flexion.
BUMPER SELECTION (Figure 7)
The bumper determines the amount of stance flexion.
• Insert small flathead screwdriver under bumper and lift upwards.
• Remove bumper (leave the shims under it in place).
Patient Weight
14-20 kg (30-45 lbs)
20-29 kg (45-65 lbs)
29-36 kg (65-80 lbs)
36-45 kg (80-100 lbs)
• Install appropriate bumper according to patient weight.
• Active patients may require a stiffer bumper
• Patients who have previously worn a prosthesis without a stance-
flexion feature may initially prefer a stiffer bumper.
• We suggest trying a softer bumper after two weeks of trial. This helps
the patient develop security with the knee. Doing this will also help
make the transition to the stance-flexion characteristic more
acceptable.
