The Össur NOH5 and NKH5 are polycentric knee units which are geometrically locked at heel strike. At toe-off the knee unlocks to allow a smooth transition into the swing phase. This is controlled by a hydraulic unit with three valves, two controlling the flexion and the third controlling the extension. These are independently adjustable to suit a range of walking speeds. The NOH5 is supplied with a male pyramid adapter to allow angular adjustment. The NKH5 comes with a laminating adapter, complete with adjustable alignment discs, making it particularly suitable for patients with very long residual limbs.
