Hi cshs78, I also am what I guess I'd call a "sweller" too: my inside knee swells very quickly in response to, well, everything! I'm at 3.5 months out now and finally, since I stopped doing PT a couple of weeks ago, the swelling is down, my flexion is improving daily, and now, only now does squatting actually FEEL good! I'm supposed to be using my butt muscles more, per PT, so I do squats holding on to my kitchen sink. BUT, I did not try or even have PT suggest I do squats even this modified way until I was 2.5 months out!
On here it sounds as if here in the US, there is still a tendency to push TKR patents as if we were young athletes recovering from a sports injury. The old "No pain, no gain" mentality isn't correct for us though it might be for an injury recovery. We aren't injured; we're healing from surgery, 'fer gosh sakes! It's a different "critter" entirely.
Initially, my PT was also wanting to push me to do more to regain flexion and extension and I did cancel a PT session as I was just in too much pain. This is before I found Bonesmart, of course... Once I said I wanted to back off and work on specific tasks I needed to improve, she switched from her normal mode to helping me accomplish my goals: going up and down stairs, walking more smoothly, walking without swinging my leg out and around (I was pretty knock-kneed and had adapted to swing my leg out and around my other knee; not good walking habits for straight leg like I now have, on one side at least)... etc.
As Kneeper and Suz, and most of everyone here who's been through it says, "Less is More"!
One of the benefits of this forum it feels to me is the discussions here "give us permission" to retake control of our lives now that we have our new knees. We can and should say no to that which causes us harm; that's a sensible coping habit of healthy folks. We can say no to specifics of PT or to PT in general, depending on the value we feel we get from it. I didn't stop PT until my prescribed slots ended, but I did modify what I was willing to do and experience and I'm doing much better now! I had to go back to work sooner than ideal, too, but I made it work, iced alot, took ice packs to the store with me, used them then put them in the freezer there, etc.
Hang in there, as we all recover and heal at our own pace, not the pace someone thinks we should! You can do this, and we're all here to help cheer you on!
