Key Features

The Össur NOFM1 is a small polycentric unit which can be used as a free knee with geometric stance stability, but which also comes complete with a lock mechanism and thigh release. The versatile NOFM1 is supplied with a male pyramid adapter to allow angular adjustment and the NKFM1 comes with a laminating adapter, complete with adjustable alignment discs, making it particularly suitable for patients with very long residual limbs.
