Just how bad they were and how much better they are now

I got my images of my knees today on a disc. I compared them to the ones I had from last year. It's like night and day. No wonder they feel so much better. The ones at the top are after the surgery, the ones at the bottom show the pre-surgery arthritis. It was definitely time. There was no cartilage at all. Since I'm a month out from surgery today, physical therapy was mostly functional testing today, so I'm hurting a bit, maybe a 4/10, but lately I've been a 0 or a 1, 2 tops, even with the range-of-motion bike, which is pretty amazing, especially since I was regularly an 8. Whoo-hoo!
