After a couple of days of aches and pains due in part to the very changeable weather we were having, the knees are behaving very well today. I've been able to walk up and down stairs with only a little reminder of my surgery.
Everyone keeps telling me that if I continue to do my exercises, either at home or at the therapists, I should see major improvement between six and eight months. And, after a year, I should need to be reminded that I had surgery. That would put it around the middle of January (six months) at the earliest.
Believe me when I say that I will be doing my exercises on a regular basis.
