Just like you I had been told after Arthroscopic surgery
on both knees
that I was bone on bone and needed TKR on both
knees. After lots of pain and meds plus more than one doctor's opinion I decided to go forward. So last August (2012) I had my left knee done. Long story short! The pain I feel today is worse than EVER, encompassing my knee, leg, hip, ankle and now back. I cannot walk, sit down, get up, cook, kneel, lay dpwn on my back without severe pain.
