Exercise! - Oops Sorry About That Post Here Goes Again Re Exercise

I had my kneecap realigned with surgery last september and am still having pysio to help me to walk again. I need to lose a stone and was wondering what sort of exercise I can do to help me lose this stone as I cant use an exercise bike or walk very far so any ideas or thoughts or help BADLY needed please?

I think your physio therapist would be the best person to answer that question....
