This is from BUPA mate.
This is a link from the site for you with some extra background info.
If and when you get it properly diagnosed feel free to PM me and I can give you some tips on rehabilitation.
I work in Rugby in Ireland now formerly in Aus and also in the UK and as I am sure you are well aware your injury is not an uncommon occurence.
I'd be happy to give you advice and more background on current best practice with regard to either surgical or non surgical knee rehabilitation.
