Has anyone tried acupuncture for breaking up scar tissue?

I was searching the ‘net for non-invasive ways to break up scar tissue from a surgery that I had done on a joint. I have not gotten back the mobility I would like with physical therapy, and I read that acupuncture can be used to break up scar tissue. The surgery was 2 years ago.

Has anyone had acupuncture for something similar? Could there be a downside to trying it and seeing what happens (ie risks, side effects, etc.) What are your experiences in general with acupuncture? I have never gone and am skeptical, though some people I know do like it.
