question: I had an arthroscopy on my knee which wasn't effective and recently fell down some stairs which has really aggravated it -constant pain and immobility.  Going on holidays outside Australia from  May - late August. Have thought about stemcell treatment but am dubious.  Is there anything else available.  Sadly my surgeon Neil Openshaw passed away unexpectedly so I can't see him.  I live in Dunsborough and am a 69 year old female.
