Plastic Polycentric Knee Joints - Black

Item #: 7U56=S

Polycentric knee joint bars with gear drive

Added to your shopping cart

Overview

Joints have interchangeable stops (ranges listed below) to limit extension as well as flexion concave half-round bar profile. 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.
