MCP Arthroplasty?

I recently dislocated my right pinky. This finger had been broken and/or dislocated several times in high school, but never treated. Since then, it has only been a minor problem. It was pretty bent and lumpy prior to this recent injury and it is really jacked up now. My doc referred me to a hand specialist, whom I have yet to see. My initial research on the web leads me to think that I may be a candidate for joint replacement. Anyone have any experience or advice?
