The knee has a polycentric design comprising pivots connecting a chassis to a main body via
three link arms. A hand-operated spring-loaded pin operates within a latched slot in the body.
The pin may be located to engage into the chassis and lock the knee in full extension. A housing
is bolted to the distal aspect of the knee into which is clamped a foot/shin component. The shin
may be shortened to suit the user. The sole of the foot features an anti-slip tread pattern.

The lock is hand operated. To lock the knee release the acuator from the down position, fully
extend the knee and push the actuator up to the top position and ensure the actuator is fully
engaged as shown.
