I think it's time to stop having your knee measured and stop doing all those exercises. They obviously aren't doing your knee any good. What you're doing isn't working, so you have nothing to lose by trying something different.Knee flexion still at 85-90 range. Extension is -8-12 most times; not sure why it won't go straight or why I have to work on it everyday and don't keep the numbers. SIGH PT had me do a new exercise yesterday; the stair stepper for 5 minutes. I did not have any issues or feel any difference in my knee at all. By this eve ink my knee feels strange; stiffer and sort of pain I've never felt at top of knee, possibly kneecap.
Instead, try a complete break from all exercise, except for just doing the bare minimum around the house.
Instead, concentrate on trying to reduce swelling, by spending lots of time resting, icing and elevating.
Take a vacation from PT. Give yourself and your knee a break.
You do know, don't you, that you don't have to work hard to recover a knee?
TKR: work “smarter” and not “harder”
