As a PT I have to agree with dsrunner about the nutritional support which will be better than NSAIDs. At this point the NSAIDs are inhibiting any healing process that may occur. All the procedures you recieved only treated the symptoms not the cause. You should be asking why did this occur in the first place. I don't know where you live but I would again look for a PT who is not only a runner, but inclined to look at you from a holistic perspective from the ground up. It sounds like your knee got caught in the cross hairs of a kinetic chain dysfunction from either above or below the joint and this is still ongoing. No more surgery, find somebody who is willing to take the time and evaluate you both ortho kinematically and well as arthrokineticmatically, when you find that person they will know exactly what I am talking about and where to look. Best of luck to you, stay tough!
