Responses – knee orthosis for femoral nerve palsy

Ted A. Trower

My original post was as follows:


I have just seen a gentleman who experienced a unilateral femoral nerve

palsy post spinal anesthesia. He is now four months post injury and is

getting significant return of function but is still experiencing

uncontrollable buckling of the knee. I was thinking of a KAFO with offset

knee joint and a solid ankle but after seeing him I think he might be able

to get along with less hardware. Is there any knee orthosis that offers

improved resistance to knee buckling in the presence of weak quadriceps?


The bulk of responses are clearly suggesting the use of a ground reaction

AFO. I had considerered this but I really hate to lock up a perfectly

normal ankle. This is the reason I was not satisfied with the idea of using

a KAFO. I would prefer to attack the knee directly if it can be effective.

Thanks to all who responded.
