Polycentric Knee Joint

Stainless steel With gear drive, free motion joints, concave half-round bar profile, interchangeable stops to limit extension

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.
