Key Features

The Össur NOH7/NKH7 is a polycentric knee unit which is 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 NOH7 is supplied with a male pyramid adapter to allow angular adjustment. The NKH7 comes with a laminating adapter, complete with adjustable alignment discs, making it particularly suitable for patients with very long residual limbs. The NOH7/NKH7 has the same mobility rating as the NOH5/NKH5, but some specification changes, allow an increase of the weight limit to 136kg.
