At age 51, I went to an orthopod to see if I could get my blown knee repaired. Upon expamination he said that "that knee had been repared a couple times already - a long time ago". When I said yes, 1967 & 68, he said well, "they couldn't do a very good job with knees back then, and we can't do a very good job with them today". 'Course, those are Canadian Dr's he's talking about.
; Good luck, Tinker.
