1.1 Construction and Function

The 3R78* Prosthetic Knee Joint is a polycentric prosthetic knee joint. It is available in the follow­
ing versions:
• 3R78 (with proximal pyramid adapter; in combination with the 4R156* Tube Clamp Adapter
for hip disarticulation)
• 3R78=KD (with proximal lamination anchor for knee disarticulation)
• 3R78=ST (with proximal threaded adapter for long residual limb prostheses)
The upper joint section
and the posterior link
tion is located above the joint and behind the weight bearing line, thus providing knee stability
in the stance phase (see fig. 2).
The prosthetic knee joint features a large flexion angle (150°) (see fig. 3). It is equipped with auto-
adaptive, pneumatic swing phase control for walking at different speeds. Flexion
damping can be adjusted separately and individually (see fig. 4).
The integrated extension assist spring is part of the swing phase control mechanism and ensures
extension of the prosthetic knee joint.
