I've had a procedure for Dupuytren's contracture, not what you have but maybe relevant to others.
Was advised not to undergo surgery too early as this will typically return after surgery and will subsequently require more surgeries into scar tissue.
I opted for this surgery when my little finger was clubbing at 45deg and adjacent finger at 20deg. I was told a skin graft at same time would reduce likelihood of reoccurrence.
Extremely happy with the results after 18 months, 100% movement and strength. Recovery was about a month.
