Key Features

The Össur NOFM2 is a small lightweight monocentric unit which can be used as a free knee with weight activated stance stability, but which also comes complete with a lock mechanism and thigh release, making this a very versatile unit.

In position 1, the knee will lock automatically when extended. For position 2, lifting the lever up to the first stop position will unlock the knee, but upon release, the knee will automatically lock again on extension.
