Although I've never had knee replacement, I know a a couple of people who have had it. One of the people I know is a firefighter, he's on light duty right now, but, they expect him to have full use. They wouldn't even let him back to work, if there was any question about him doing his job. Another person has had 2 replacements, and does anything she wants! Skiing is her favorite sport, so she's at it all the time, and with just as much vigor, as ever! Good luck. If you want it, you'll find a way to get it!
