3R90/3R92

Improved Technology and Fresh Design
Friction and wear are minimized through state-of-the-art bearing technology.
The brake mechanism has been further optimized resulting in a high degree of functional reliability and an extended life while also allowing for a broader range of adjustments.
A new extension stop bumper will provide improved extension damping.
Lastly, a fresh appearance highlights the technical innovations.

3R90 with mechanical extension assist
(Fig. 1)
The effect of the integrated extension assist can be regulated very easily by adjusting the tension of the spring. The setting can be engaged individually in five settings and increases or decreases the intensity of the extension assist.
3R92 with dual-chamber pneumatic system (Fig. 2)
The pneumatic swing phase control allows a significantly smoother gait for the user. The flexion and extension damping is individually and continuously adjustable to match individual requirements. In particular, users with Mobility Grades 2 and 3* will appreciate the smooth and energy-efficient functionality of the progressive pneumatic swing phase control.
Further advantages of the 3R90 and 3R92
-
The excellent stability provided by the weight-activated brake of the 3R90 and 3R92 makes it easy for patients to switch over from a 3R15 or 3R49.
-
Both the 3R90 and 3R92 offer an improvement over conventional friction-brake knee joints because they release during forefoot loading, allowing the user to initiate swing phase without having to hip-hike.
-
A 34 mm tube adapter is included for added value.
-
Both joints are rated up to 275 lbs/125 kg to give you an increased fitting range.
-
Newly designed plastic cover protects the internal mechanism as well as the external foam cover.
-
Easy to align: The blue ring on the upper section (Fig. 3) makes alignment easier. The plumb line is simply placed at the outer ring of the disk allowing the recommended 15 mm posterior placement to be easily located without measuring.
-
The 3R90 and 3R92 offer adjustable stance flexion, which acts as a shock absorber, thereby reducing the amount of stress on the body.
