get to your MO soonest and get a referal to a Remedial Instructor / Regional Rehab Unit.
They will assess you, tailor a fitness programme for you - and get you back building bridges in good time
some of the exercises they give you seem a bit 'nancy' - feels like your training for the ballet - but it all works
you will have lost a bit of your 'proprioception' - try standing on your good leg unsupported and youll find that your balance is off ! its amazing how a little operation can upset your balance mechanism.
youll be fine as long as you dont cut corners - if they say no running for 10 weeks, then wait ten weeks or youll end up back inthe sh*t at the start again.
