Just found your forum here and thought I would join in. I had a lumbar fusion with hardware almost almost three years ago. And it did eliminate alot of my back pain. And with meds I can't hardly feel any pain . But now I am having alot of knee pain and the docs are suggesting a knee replacement. I'm only 40 and I am a little concerned about going thru with it. I know this is a back pain forum but has anyone had any experience with this surgery too ?
