Scott, a close friend had the same systems you are talking. He was a professional guitar player. He had the surgery, his hands functioned well the first year. When the problem returned, they gave him short mini surgeries – not very effective.
I strongly suggest physical therapy; have orthopedic surgery if all else fails.
I have Parkinson Disease, some of the systems are the same. I go to physical therapy two times a week – there are days when I feel improvement, and days when there is no change. The good news is that I am not losing my battle; I am holding my own.
Scott, this is the best that I have, John C.
