Last Friday, a doctor made three tiny, 1-cm slits in my knee, played what must feel like a video game to manipulate a camera into one and tiny little clippers into another, and removed a tear and a bunch of loose cartilage that had been causing me knee pain for 10 months now. Sewed me back up with stitches that don't even have to be removed cause they'll be absorbed by my body.
(I think going by the timestamps those are 4 before and 4 after pictures, but I haven't talked to my surgeon since then, so that's just a guess.)
I was hobbling around without crutches by that same night. Five days later I'm already walking better than I was before the surgery, and I even went to the gym this morning. As far as I'm concerned, we're already living in the future. Huzzah!
