The Mono is a 5° extension and flexion free knee joint. Patients with paralysis in area S1-L4 can actively move this joint using all or part of the knee extending musculature.
The axis of rotation has been shifted back in order to increase stability and to avoid any possible jamming of the soft parts during very intense bending.
