Well, I got a total replacement of both knees on May 21. Surgery wasn't much fun and the first couple weeks afterwards were pretty much torture (even more so for my wife!).
Rehab has been painful, tough, but rewarding. I seem to be back to 'almost' full range of motion with both knees and there's not much pain anymore, except after big rehab days or hiking, biking, etc.
Today was my first day back on skis and I'm stoked. It was only a remnant snowfield at the bottom of Four Shadows Couloir in Cody Bowl, but the snow was great, the weather was beautiful, and my knees felt fantastic. I was in serious withdrawal as until this May, I hadn't gone without skiing for more than a month in nearly 17 years.
It felt SOOOOOOOOO good to be back sliding around on snow...
The wonders of modern medicine.
