Joints with interchangeable stops (ranges listed below) to limit extension as well as flexion. Concave halfround bar profile, anatomically pre-shaped, with adjustment slots. Thermoplastic joint bars have a forming temperature of 150° C/302°F.

Practical recommendation:
To align the orthosis knee joints with the compromise pivot point according to Nietert, the 743Y56=1 size 1 adjustment adapter is aligned with the compromise pivot point. Therefore the compromise pivot point of the polycentric gear drive joints is centred between the two joint screws.
