question: I was told today that the result of recent xrays on my knees turned up a diagnosis of hypertrophy of the knees. I have osteo arthritis (since 2004) & am wondering what this is & how serious it is. I have been in pain all during the month of October 2011, but my symptoms have subsided this month. I was recently prescribed tramadol for the pain which I have been taking sparingly because I know it is habit forming.
