I had an orthoscopic bilateral release done on my right knee in 2012 following an injury back in 2011 and it went great was fully recovered and out of physical therapy within 3-4 months. However I had one done in october of 2013 on my left knee becuase i was having pain and it kept locking up and hyperextending. My left knee has always been my bad knee it has always hurt in 2007 I tore the cartlidge in it but i healed itself. I have now been in physical therapy since the end of october and still currently in it and my knee is not getting any better at all. If anything the pain has worsened and I am not sure why. I had another mri and they say theres no injuries but that i do have a cyst on my acl but that can not be causing my pain. Does anyone have any ideas at all? I am in constant severe pain with this. Please and thank you
