Permanent numbness is best, as my knees are coffee table height!!
I've just come down to earth after that wonderful display from England.
I found that one or two crutches always helped me get around if the knee was hurting, although like most men I used to show I didn't need them.
When the knees stopped hurting, with no crutches I used to walk like a ruptured duck. When walking I used long strides with my good leg, short steps with my bad one. That made me waddle, and gave me shin splints, which are painful.
So taking advice from my PT, I use just one elbow crutch on my good side. I move it forward to the proper stride length, then bring my bad leg forward to match it. I hope that makes sense.
I use elbow crutches, which I find are perfect.
The good gait didn't come naturally, it needs practice, took me about a couple of weeks. But I still take one with me on walkies, and use it when I get tired. Try to make sure you put your heel on the floor first, the roll your foot as you go forward. When I started I used to point my toes upwards to make sure they don't hit the floor (which hurts) but as the ROM improves you can drop the toes and that's even better.
I now walk properly all the time, with or without my crutch.
Pleased Brexit keeps you amused, it really is laughable, but most people here have given up caring. If we didn't laugh, we'd cry.
You seem to doing all the right things, it soon all drops into place, and you will be zooming away.
