2011-2016 3 surgerys and frustrated

There is nothing wrong in having second, third or even fourth opinions. After the second opinion there is no point in going any further.  What type diabetes do you have.  Have you gone down the glucosamine route (though apparently if they havent worked after 3 months, they never will!) The swelling is just the knees way of protecting itself, if you can bear it; massage it, it might even help ease the pain.  Have you tried acupuncture. Does not always work, but you never know!  The burning is your nerves in that particular area and can take time. There are procedures you can have that "interupt" the pain messages to the brain, but again, you will have to discuss this with eiher your doctor or your pain management consultant. If you have one of those, it can be a godsend. They are independent, there are no drug companies to sway them one way or another, they will go through every single thing out there with you.

With regard to hyper extension, you need to work on your muscles more. By really working at it you will strengthen everything and will help diminish the grinding/popping sensation. Is it just the tear that you have had repaired. The reason I ask is, if it is, then perhaps look at your diet. Foods like tomatoes, peppers, potatoes can actually worsen your pain, I know it sounds more like hocus pocus, but I kid you not.  If you go onto an arthritis website look for foods that can help and also what to avoid. It will not cure your osteoartritis and joint degeneration, but could make a huge difference in controlling the pain in your joints.
