Here we go again. After a very successful hip replacement in March of this year I had a total knee replacement (knee arthroplasty) today. I also got a new knee cap, whatever that's called. This knee had been going down hill slowly since I had the leg crushed in 1982. I haven't been able to straighten the knee since then, and the doctor measured the angle at 19 degrees. The new knee has only a 1 degree bend. The muscles and tendons are all accustomed to the old bend and they'll need much stretching to give me full use and movement. I'm totally up for aggressive physical therapy and dedicated stretching, even while sleeping. I'm up walking with a walker already, but the nerve block in my thigh hasn't worn off, even after twelve hours, so I still have to move carefully. Food is good, nurses are nice, and I've watched more television today than I've watched in many years. I go home tomorrow morning and start my extended holiday vacation. My lighted pulse oxygen sensor looks like something from ET. "ET phone home."
