The OFM1 is a polycentric hybrid knee joint with a stable aluminium
frame construction.
The OFM1 is used for patients with above-knee amputations.
The OFM1 allows the pyramid adapter to be rotated and AP/ML
corrections of up to 5 mm to be made.
Because of the unique construction, both versions can be used
as either a locking joint with manual release or a mechanical,
freely mobile joint as the user grows more mobile. The joints
are suitable for users with low walking demands (mobility I
- II) with a high to very high need for safety.
