Hi, I’m a newbie, but, looking for answers to what I’m starting to think is a failed TKR. I’m six months post op left TKR due to a subsequent fall and patellar fracture of same knee. Had ORIF surgery on patella, but just wasn’t walking normally about 5-6 months from surgery. I got a second opinion from a different knee surgeon, who explained that I had a lot of arthritis from previous surgery and I needed. TKR. Now, I’m six months post op and I feel I’m worse now than before surgery. I have some pain , though minimal, but my knee is unstable and buckles, so much that I can’t walk without a cane or walker, plus I get unbearable back pain with walking, so can’t go very far without having to sit. Anyone else have these symptoms?
