HF, the tightness and swelling is very normal, sad to say. You're just 2 months out and it will last for a while longer. It's uber aggravating, I know, but it will get better in time. Maybe 2 weeks, maybe another 2 months. I honestly had the tight feeling well into month 5, but I don't have it anymore. I do still have the swelling and my knee feeling heavy/full most of the time, but even me, the slowest recoverer on the planet apparently, is getting a tiny bit better every day. I promise it will get better - it just takes time.
