Errm, personally I don't think changing your running style will benefit you, but you may not want to listen to what I say.

The affected area is going to be riddled with scar tissue so you may want to take steps to get rid of it. Scar tissue is less flexible and more prone to further microtearing. There is an article in a past fellrunner by Denise Park on cross friction massage which may be of interest to you.

In the long term you will probably need to spend the next 3-5 years committing to a daily program of progressively increasing weight bearing exercises, coupled with daily stretching. I can't advise you on what to do, but I'd be doing both eccentric and ecentric loading if it were me.

You'll probably only get one shot at doing this properly, get the right advice from a good private sports physio. If you try and cut corners, you're screwed.
