PVNS? What is going on in my knee?

I had surgery just about 4 months ago.  It was an orthoscopy.  Is it orthoscope or arthoscope?  I'm not medically trained but apparently people in different countries have different spellings.  They even completely different names for PVNS.  But that's not what I'm talking about today.  I'm talking about just over the last week my knee has been doing it's old thing when there was PVNS in there.  Popping/cracking knee, difficulty getting down stairs or fully bending the knee at times.  I was doing great in my recovery since my surgery up until the newest onslaught of symptoms.  Even the shooting pains are back.   It's very possible it's coming back.  I will need to wait at least 2 more months before I should have an MRI to see if anything is detectable but I have heard stories that PVNS grows back much faster after it's been tampered with.  Such as the stories of people having an injury and then experiencing rapid growth of PVNS.  Even the surgeon who did my first PVNS removal surgery said that once PVNS has been irritated it grows faster.  Or that was his observation.  So now that I've had 2 surgeries maybe it's back already.  I recall after my first surgery nearly 4 years ago I noticed the symptoms of it's return 6 months post-op.   The issue I now face is what will it look like to get surgery with the way things are going politically in the United States?  For now it sounds like it will be possibly more expensive for me to keep living in this country.  If they can't get it right in America I could become poor unless I find a country that is more sympathetic to my knee situation and not as expensive to maintain these constant surgeries I face having possibly for the rest of my life.
