Since my original post I have received a limited number of responses. What follows is the original post, then a short narrative detailing the responses.
original post:
I am trying to conduct a general survey of your choices in prosthetic knees based on single axis vs. polycentric/multicentric. In light of recent advances in technology I find that when helping a client choose a prosthetic knee that suits their particular needs, a multicentric knee is being chosen more and more frequently. I know there are many different types and makes out there and some with stance flexion, some hydraulic, some pneumatic etc.. In general, do you as practitioners use many polycentric/multicentric knees in your practice? If so, which ones do you use, and why? What criteria do you employ in the decision making process? I feel that the knees available today exceed the standard set years ago about polycentric knees only being for knee disartic's and require more maintenance. I would appreciate your thoughts on the subject and will post replies. Names withheld on request.

The Century XXII knee came in with the overwhelming majority of the vote with only one mention of durability issues. I have used this knee on many occasions and agree that it is a very good choice for many amputees.
Otto Bock was mentioned often, in particular the 3R60 multicentric, hydraulic knee with stance flexion. All the Otto Bock 4 bar knees were mentioned as good choices. I almost routinely use Otto Bock knees myself and like the 3R72.
Daw knees received high marks as a good choice but found it interesting that every mention of Daw knees included a by-line like 'there good but heavy' or 'if weight is not an issue then I like Daw...'.
The other knees mentioned were the Seattle select and the Ohio Willow Wood Geoflex knee.
There was one question raised that I was glad to see because I have asked it myself. Why is there only one four bar frame for an S-N-S cylinder? Look at the proliferation of available single axis frames for an S-N-S, but USMC has the only choice for a four bar S-N-S.
