@sandie2749 I can understand you wanting to call a lawyer after being in pain for so long, but honestly, most probably nothing will come of it. I knew a woman who was in agony for two years. She finally found an orthopedic surgeon who figured out her problem, and it was definitely an error on the part of the original surgeon. He fixed it and she tried to sue but it was impossible. I think there has to be willful neglect which is impossible to prove.
I hope you are seeking other opinions, from the best possible orthopedic surgeons available. Go out of the area where the original doctor is, doctors tend to be reluctant to say anything negative about another doctor in the same area. We are in southern NH and the surgeon who found the problem and fixed it is in Boston, at a major medical center. Those are the best places to go for something like this.
I hope you can find a resolution to your problem, no one should be in real pain like that for so long. I have had two TKRs. Granted, when I do a lot of exercise one in particular will be uncomfortable the next day but I wouldn't say it's pain. My biggest problem is that I don't have quite as much flex as I would like, but I can live with what I have -- about 120°.

14 months out and still have clicking. Knee wants to give out sometimes while just standing and numb foot. Wad told same thing give it a year. Then told 2 years now 3 years. But my numb foot came from the popliteal artery being pinch off during TKR. Finally my primary said it's not normal. I had surgery on the artery. Then had nerve testing done which showed nerve damage. My back had also been giving me new issues. Had a steroid injection in my back and that surgeon told me my TKR surgeon pinched more than my artery. It is never a Drs fault! Or at least that they will admit to.
Good luck
