I am 16 months out and my Dr. says all looks well. I finally gave in and did a genicular nerve block to prove it is not a nerve issue, I went to vascular and my veins are all good so I went and saw another person in the same group for a second opinion and he sent me for a bone scan. It shows a photogenic defect from a right total knee replacement and a mild surrounding radio tracer uptake is an expected post-operative finding. It also showed moderate degenerative radioactive tracers around the left knee and it's not really bone on bone but doesn't give me the issues that this right one does. However I have a pulling from below my knee to the top of the knee and what feels like a baker's cyst behind. I also still have the clicking once in a while as well and it never really goes away. I'm waiting to see the Dr. next week to talk about the results. I can't take nsaids either and Tylenol doesn't really help. Heat does but I can't walk around with heat on my leg all day as I'm really active. I hope you are able to find some answers and can get a second opinion. A year didn't happen for me as well and I've done PT 4 times but others have amazing outcomes. Definitely get a second opinion.
