I've gotten some great responses to my question about a locking knee that
can also operate in free swing. The responses are contained below. Thanks
again to everyone for their thoughts and ideas.

-There is a relatively new knee from Otto Bock that you may want to check
out. It's a WASC knee with a locking mechanism, and I believe that as/if
the patient progresses the locking mechanism can be eliminated so that all
you have is a safety knee- which of course you can probably adjust out to be
free swing with no weight activation if you really wanted to. 3r93
- Otto bock has the 3r39. The lock can be disabled. Pricey tho.
- Try the OFM2 by Medi. Has worked very nicely as locked knee & can be
easily switched to wt activated friction knee w/extn A. If pt warrants
progressing. Cost effective, simple & durable. I can attest to the latter
as I have a mentally challenged 41 y/o male using it as locked knee.
- Medi has a nice four bar locking knee....I have started using the balance
knee from Ossur with good success in low level patients.
- Medi OFM2
- Ive had really good luck with the two Medi OFM knees. All the details are
in the catalog. Easily switched to free and ext assist. Just depends if
you want poly or weight acivated stance lock. The cable end is a little
tricky to fab into a socket but I can let you know how Ive done it if you
- KX06 Endolite 4 bar. I personally used this knee when i was first being
fitted for my first prosthesis. It has an easy to use lever on the back
that will lock the knee in place and is able to be put into free swing
utilizing the same lever on the back of the knee.
- Medi has a few. The OFM2HD is friction or manual lock. OFM1SF is manual
- I like the OFM2 from Medi. Ossur has a 4 bar style knee, that is
lightweight for lower k-2 level patients. It is called the Balance.
- I've been very happy with Otto Bock's 3R93 (

also used the Medi OFM2.
