I've been told at least 1 yr ago that I have a bone spur behind my left knee. It never bothered me and OS was surprised by that. Fast forward to about 1 month ago when the back of the knee began to hurt. Light bulb went on and I remembered about having a bone spur there. Left knee is and always has been the more painful one. Even though xrays show more damage to the right. Odd. I picture the spur slowly shredding everything that's around it. Is that accurate or is that crazy? Another question. Do bone spurs complicate TKR? I picture the spur attached to knee and being 86'd along with the old knee.
