STABILITY AND SAFETY
The single axis joint has a stable and light frame built of aluminium-steel
alloy with a proximal integrated male pyramid and a distal  mm tube
clamp. The Össur locking knee offers a locking mechanism that can
easily and effectively be unlocked by means of a release cord.
The Össur locking knee is designed for long-term use. Other than the
biannual inspection and the use of lubricant – or Centra Lube Oil
, the inner components do not require any additional maintenance or
adjustment.
The joint will lock audibly by means of the locking mechanism built into
the lower part of the joint and thus safeguards against accidental
bending through the knee. By engaging the release cord, also under load,
the mechanism is released, consequently enabling movement.
THE ÖSSUR LOCKING KNEE IS RECOMMENDED FOR:
• Low activity users that require a high degree of safety
• Bilateral transfemoral amputees
• Training prosthesis
• User with a body weight up to  kg ( lbs).
TECHNICAL DATA
• Material: aluminium-steel alloy
• Reference height (from centre of knee):  mm
• Weight of knee:  g
• Weight limit:  kg ( lbs)
• Maximum Flexion angle:  degrees
ASSEMBLY INSTRUCTIONS
The Össur locking knee is delivered ready-to-fit.
• Assemble the prosthesis: socket, knee joint, shin tube, adapters, foot
module and shoe. The reference line corresponds to the load line.
• Align the tube adapter vertically, taking the heel height into account,
to ensure optimal functioning of the knee joint.
• Tighten the pinch bolt of the tube clamp with  Nm and secure with
Loctite .
• Determine the position of the socket according to the stump position
of the user. Össur recommends °–° (minimum) flexion and
adduction. Take into consideration contractions and the resultant
changes of the load line.
• Position the socket so that the reference line bisects the lateral side
wall of the socket and falls through or not more than  mm behind
the axis of rotation of the Össur locking knee.
• Determine the correct length of the prosthesis
• The release cord should run along the lateral or anterior side of the
prosthesis.
TO ASSEMBLE THE RELEASE CORD ON THE ANTERIOR SIDE OF
THE PROSTHESIS:
• Mould the screw insert into the socket at a desired location.
• Attach the knee joint to the socket.
• Fasten the handle assembly to the socket with the screw and collar

washer.
• Thread the release cord through the plastic tube and metal fastener.
• Thread the release cord through the central hole in the knee and
again through the metal fastener.
• Shorten the release cord to the length that suits the user and make
sure that the release cord is slightly tensed.
• Crimp the fastener by pliers or pinch the centre with a punch and
mallet.
• Secure the plastic tube to the socket with a small amount of super
glue or other means of preference
TO ASSEMBLE THE RELEASE CORD ON THE LATERAL SIDE OF THE
PROSTHESIS, FOLLOW SAME INSTRUCTIONS AS FOR ANTERIOR SIDE
EXCEPT:
• When running the cord through the central hole in the knee, use the
crimp.

• Please ensure that the release cord is not impaired by the cosmetic
cover, so the cord can move freely without friction.
• Bench, statically and Dynamically align the prosthesis to the user
Further adjustments of the knee joint are not necessary.
MAINTENANCE
Biannual inspection
In order to guarantee perfect functioning, the Össur locking knee must
be checked at least every  months with regards to the following:
• Assembly
• Secure locking of the locking mechanism
• Release of the locking mechanism
• Damage or wear and tear of the joint, release cord and screwed
connections
• Any increase in weight of the patient (weight limit)
• Dirt in the knee joint
The joint must also be inspected when it has been subjected to
extraordinary load (e. g. a fall).
Cleaning
Clean the joint with a soft cloth and some benzine. Do  use
compressed air or aggressive cleansing agents.
Use of lubricants
Lubricate the joint at least every  months with general purpose oil (-).
Flex the knee joint. Place few drops of oil on the joint. Move the knee
several times and wipe off excessive oil with a soft cloth.
WARRANTY
If the Össur locking knee is used as prescribed and for the designated
