My aunt had knee replacement. It took her a year to get normal'ish. I don't think she ever got full rom though. You are determined and having already fought through a lot of pain with it in the past, I'm sure you'll be back in the saddle soon. I had to lower the rearsets on my 16' 10R because the angle was too much for my right knee. I damaged it and had 1/3 of my meniscus removed 10 years ago. I lost rom from that actually. But, today I can run and what not, just not totally perfect. Left knee is torn now as well. Anyway, like obijack said though, the naked bikes are phenomenal. If it comes down to it, you could pickup any number of more comfortable bikes that rip. I sold my 14' Monster 1200S to one of my best buds. That bike was so comfortable and it absolutely got it done. Faster than most bikes up to 100 and can hang with super bikes on the mountain passes. Amazing machine.
Anyway, good luck on the healing process. PT is key for certain.
