Hi Andrea,
I'm so sorry you got disappointing and worrying news.. I hope you get the info you need and that everything works out..
Yes, I have heard about the tendon transfer, or ATTT (for anterior tibial tendon transfer, I believe). It something that is done to handle relapses in older children.. I have heard that it is very successful and fairly straightforward compared to other surgeries. One of the links below tells more about it.
You might want to post at the Yahoo clubfoot group; there are several parents there whose children have had this procedure and could give you their perspective.
Here are some links to info on relapses that might help:
