Good news. I am about 2 weeks ahead of you and still have odd pain issues now and then too. Last night was one of those nights. But I agree with the rom comment. I was at 103 the day after surgery, and 120 when I was discharged from PT at 4 weeks. I measured the other day with my phone app -- can't guarantee how accurate it is -- and was 125 then. My PT said he could tell I would do well from the beginning. That's not to say that people who struggle with their ROM won't go on and do equally well down the road.
I still do have swelling -- mostly above my knee now -- and the stiff band feeling. They are gradually improving and staying reasonably active seems to help. I think I overdid a bit yesterday and paid for it when trying to sleep last night. I do notice that my swelling actually decreases when I do something active. I do believe that, in time, this will be behind both of us and we shall be thrilled we did it.
