Wednesday was THREE MONTHS on my newer knee (soon will achieve 8 months on number 1)...
I am comfortably taking a one mile walk most days, often with a second half mile walk (walks are early morning and after dinner to avoid ongoing afternoon warmth). A few days ago for the first time I did a mild-moderate hill loop behind the house, about 3/4 mile, and was pleased to take it at a good pace and zero ill effects same or next day. My goal over the next ten days is to extend walking to 1.5 miles.
I returned to yardwork yesterday morning, 20 minutes (didn't take a walk!) Was fine, zero swelling at bedtime; today, some anterior swelling and some aching pain at the back of the knee (no palpable swelling). Will try again in a few days with timer set for 15 minutes. I find timing activities is, for me, highly effective.
I rarely ice anymore; the body says it mostly doesn't want it. I retreat to the Lounge Doctor a couple of times a day for 20-30 minutes and spend same time in the recliner at least 3 times a day.
There's still that palpable ropy lump between front midline thigh and kneecap; it softens with massage but not for long. Flexion isn't impaired, just a tad stiff without massage, so it must be scar tissue. It's manageable.
I know my extension is at a plateau that would make a theoretical PT cry, but the extension is functional for now - stairs are taken sequentially, my stride isn't perfect but I'm not limping. Overall I feel like things are going very well!
