Ruby, I hope what I'm about to say is encouraging to you because I went through this, too.
My MUA set me back quite a bit. I resisted people's explanations that my knee was actually more of a baby because of this, and I felt many of the same feelings you are expressing. I wanted to have the same gains that my surgical twins experienced! However, I've been consistently showing milestones a few weeks behind them, and some milestones have not yet come consistently to me even at 5.5 months. The MUA did get me out of the 70s, though, and afterward my PT could help me maximize the bend better than before the MUA.
My ROM settled in at about the same as yours, daily-life-wise. I would say that it's between 90-100 most of the time when I'm doing ADLs. It was measured at 103-108 on various visits, under my own power on the table with the PT measuring, but I don't know if I could still do that. It certainly isn't that good most of the time around home! I've been discharged from PT and haven't been back for almost a month.
Ruby, I know "everyone" wants you to be at 120, but honestly, I can now walk well, tie my shoes easily, get dressed the normal way, walk up and down stairs (have to admit I have a little discomfort there, but not because of the degree of bend), pedal my exercise bike, and do just about anything I need to do. I am putting my faith in the BS assertions that ROM can keep getting better as the leg strengthens and the internal swelling (which I still think I have) goes down. I really would love to be able to ride a real street bike safely and comfortably, so that's a long-term goal.
I felt emotional and worried about all this until I got off the opioids. I now know that they affected and magnified my fear and sleeplessness, which then made me
more emotional. I hate to be a Debby-Downer, but I also experienced similar after-effects for almost a month after I discontinued their use. It's such a catch-22. We need them to get through the pain, and yet they do a number on us in other ways.
I guess I just want to affirm that your feelings are normal for what you're going through; and maybe you can glean some comfort from the probability that these feelings are also being manipulated and magnified by your body's reactions to the drugs. I know I was astounded and embarrassed at some of the feelings that were flowing through me. I am usually a strong, hold-it-all-together type of person!
BTW, when I went off the meds, I did it gradually, in a step-down manner. I think that helped me avoid feeling really sick from withdrawal. That might be especially important to you, because your body responds so sensitively to the drugs. You could ask your doctor how to do it when you're ready to wean yourself off. In the meantime, I hope you can find a combination of drugs through your regular doctor that help you continue to progress with as much comfort as you can get. I think it's well worth your while to keep pursuing options. Just remember that the doctors probably haven't experienced the pain of a recovering TKR, so their estimates of how long you need pain assistance are most likely based on a generalized experience treating others with a variety of issues. Be tough and keep asking for what you need.
And feel free to commiserate with me any time. We MUAs gotta support each other!
