It's good to hear things are progressing. I am in my 14th week, post-op left knee, and still on one crutch (or cane). The day before I was supposed to walk I woke up with a hugely swollen knee and probably 10 degrees less ROM. It's been 4 weeks since then and my knee is just now starting to go down in swelling. The swelling has totally ruined my ability to work on ROM and has made walking very difficult. On a good day I may be able to walk around with just a limp, but if I sit down for too long I have to spend a minute or two straightening it out after standing before I can take a step. So I'm battling with when to ditch the crutch and how to transition to FWB. My surgeon and my PT seem to think that it's unfortunate, but not anything bad, so I just need to wait. And of course, not supposed to take anti-inflammatory meds, so it's a lot of ice these days.
On the bright side, my right knee really has held up to the pressure amazingly well. It hasn't been sore or swollen once and has only gotten a little "clicky" when I have been standing for over a couple hours. So while my left knee isn't going as smoothly as the right, the fact that my right is doing so well gives me real hope for 9 months from now. But I have to say, the day (or night) that I can sleep comfortably will be an amazing feeling. I also have pain meds and sleeping pills, but the pain meds also keep me awake and itchy and I'm not a fan of taking sleeping pills regularly. I guess at this point we just keep doing what the PT/docs say and keep improving!
