Oh, sheesh, people. I'm just kidding. Especially right now: I'm five weeks out of getting my left knee scoped and I'm test-driving the knee this weekend. We'll see if I can cause any pain (hopefully not!).
Laura, good luck with the knee. I'd like to give you some encouragement:
I had my first of 3 scopes in 1994, then 2001, then 2010. Now awaiting the inevitable TKR next month (even though I did Whitney 2 months ago, slowly)
One orthopedist I saw in 1994 said stop backpacking. Well, he is dead, meanwhile I took my pack to 5 continents, as high as 22,000 feet, all of the JMT, and more, despite his advice. I hope you have a good outcome,too, but as everyone else told me, be patient. I am sure you will listen to your Physical therapist :-) Harvey
