INFORMATION
Use parallel bars for the first trial walk of the prosthesis wearer with the knee joint.
2.4 Construction and Function
The 3R93 Knee Joint is a monocentric knee joint with a load-dependent brake mechanism and
an optional locking function.
Due to its construction, the 3R93 can be used as a locked knee joint with manual lock release
(pulling the pull cable) and as a friction brake knee joint once the prosthesis wearer has regained
increased mobility (locking function permanently deactivated).
The 3R93 is especially suited for transfemoral amputees who are able to walk to a limited degree
and who require a high degree of stability.
Locking function
The locking function can be permanently deactivated by the prosthetist (see Section 4.2.1).
With activated locking function (delivery status), the lock mechanism, which is installed in the up-
per joint section, secures the joint in the extended position, and the latch engages.
Flexion release (e.g. for sitting down) is activated by pulling the cable, which is attached to the
cord loop. To do so, the patient either relieves the load on the prosthesis or applies load on the
toes (knee-extending moment) while unlocking the joint. Once the joint is unlocked (pulled cable),
the patient can initiate the flexion movement. For safety reasons, activation of flexion release be-
comes more and more difficult with increasing flexion moment.
A movably attached plastic flap (Fig. 2, item A) covers the anterior joint space even when the
knee joint is in the maximum flexion position and protects the cosmetic foam cover and fingers
from getting jammed.
Braking function
With permanently deactivated locking function, knee stability is achieved through the brake mecha-
nism that blocks the joint in the flexion direction under load.
When load is applied to the heel, the brake responds, stabilises the prosthesis and achieves a high
degree of stability throughout the entire stance phase. The brake also offers the desired security
when walking with a slightly flexed knee joint. The braking effect is adjustable (see Section 4.2.2).
Due to its construction, the brake mechanism does not wear down and is functionally reliable, so
that readjusting the braking effect later is generally not necessary.
Swing phase control
The 3R93 Knee Joint has a mechanically controlled swing phase. To initiate the swing phase
the prosthesis wearer relieves the load on the prosthesis to cause the brake to turn off. The in-
tegrated, adjustable spring extension assist (Fig. 2, item B) controls the pendulum movement of
the prosthetic lower leg.
2.5 Combination Possibilities
Depending on the patient’s functional demands, the following prosthetic feet and tube adapters
are recommended:
Single Axis Foot (1H32–1H40), SACH Foot (1S49–1S90), Adjust (1M10), Dynamic Foot
(1D10 / 1D11), Greissinger Plus (1A30), Dynamic Motion (1D35), Trias (1C30).
2R77 Tube Adapter – stainless steel (included in the delivery).
