Oh,
@liam2015, I'm sending you a huge, healing,

empathetic hug. You've been through so much misery with that blasted knee and the lousy side-effects of medication. You know I am also a *fellow-sweller* and it definitely inhibits movement. I don't believe there is an answer as to why some of us swell more, nor does there seem to be any treatment option beyond ice and elevation, although I will be asking my surgeon today about compression sleeves. I know there are some designed to help alleviate swelling, though I'm not quite sure how that might actually work. I tried Aleve the other day and it just gave me a slight stomach upset, so I won't be trying it again; pffft!
Do you by any chance have an exercise bike or pedal machine at home? I have found that very beneficial for loosening when at the PT office. Initially, I was opposed to the idea of buying a bike, but I'm beginning to change my mind. Despite my swelling, (which seems static) my ROM has improved in just one week from 60 to 75 on flexion. As such, I see some sort of exercise bike in my immediate future because I believe it's made a difference already. The cheesy, pedal machine is just an exercise in frustration here since it travels across the floor despite my many clever (hah) attempts to anchor it somehow.
If my flexion does not improve by the 6-8 week mark, I know the MUA discussion will occur. I've not read much about it yet, because I don't want to focus on something negative that might never occur. That said, I am wondering what your specific objections are? I know there are a few Smarties here who have undergone the procedure and seemed to have gotten good results;
@LindaO and
@Mister come to mind. Perhaps you could chat with them about the experience? There's nothing like hearing from the voice of experience when it comes to these matters, especially since your OS seems to be in a scare tactic mode. I also wonder if a discussion with your primary care doctor might be helpful? You may have already done so unbeknownst to me.
