Had a knee Arthroscope on Wed afternoon. I have had about a dozen ops on my knees courtesy of a bike meeting truck incident about 23 yrs ago. The truck won!. Had the op at 1:30, was home before 6, and today I am walking around without crutches, maybe hobbling is a better word. But I am mobile, in minimal pain. Years ago, this was a 3 day in hospital affair!. 3 Cheers for medical science! The next op is a replacement, that may be a bit more painful!.
