Thank you, everyone. I will reply to you all over the next couple of days. Your support really does mean a lot.
@Josephine here are my answers to your questions:
1 - pain levels are pretty much zero when lying down (my knee doesn't keep me awake at night). Anything from a 1-4 when sitting (depending on what I have been doing) and from 3-8 when walking or standing (again, depending on how much I have walked or stood). My pain is mainly tightness (tight band feeling), a bit of stiffness in the patella tendon area and soreness around the fat pad. I also get little zingers in the fat pad area (the numb area) but these don't cause pain, I can just feel them zinging.
2 - no meds at all - haven't taken any since the end around the beginning of October.
3 - I do still ice some evenings - probably averages out at 2 evenings a week and for about an hour each time.
4 - very little visible swelling if any. If I do get any swelling it is in the fat pad area.
5 - my PT routine (as set by my PT) is:
Short range quads (with rolled up towel under knee) - 3 sets of 15 reps
Straight leg raises - 3 sets of 15 reps
Hamstring curls (lying on stomach on bed, using good leg to give a bit of resistance) - 3 sets of 15 reps
Sit to stand onto a dining chair or the bed - 3 sets of 15 reps
Sit on dining chair with resistance band around ankle and around chair leg, straighten leg from 90 degrees to full extension - 3 sets of 15 reps
My quads and hamstrings are still weak hence the above routine. I do these exercises probably 5 or 6 days per week. If my knee feels sore or especially tight then I tend not to do the sit to stands.
I am also going about my daily life - getting ready in the morning, commuting by tube to work, spending 8 hours in the office, commuting home, preparing meals, housework, ironing, grocery shopping, socialising etc. I do tend to wear my elasticated support a fair amount of the time - always when I am outside - I try not to wear it in the office or at home unless I am doing housework or ironing etc.
Thank you very much.
