When I had surgery to correct my hip dysplasia two years ago they had to cut a lot of the adductor muscles that were twice the size of my 'good' leg, due to incorrect muscle use for over five decades.

The result was that after surgery I had a very weak leg which, (although different muscles), is probably what your leg is like at the moment. Sadly, because the surgery also involved re-building my pelvis with metal, my running days are now behind me and I have been forced into cycling.

For the first few weeks of cycling I could barely put any force through the leg, due to the surgery, but it did improve slowly. It took several months before I could apply a respectable amount of force through the leg, and nearly a year before it was as strong as my 'good' leg.

You are probably younger and fitter than me, so hopefully your recovery will be shorter. Against this, however, is the fact that cycling is easier on your muscles and doesn't have the sudden high loads that running does.

I agree with Travs that if you want to work on technique a local decent track club would be good place to go, because on a track you are totally visible to the coaching team all of the time. I would, however, recommend a very steady approach whilst recovering, as it is important to avoid re-injury from pushing too hard too soon.
