You kneedn’t worry about whether it works…

The National Institutes of Health says total knee replacement has come a long way since it was first introduced in the 1950’s. I expect so. They didn’t have CAD/CAM or selective laser sintering technology in the ’50s.

I had my right knee replaced in May of this year, and so far, so good. More than good, actually. I can walk without pain, climb stairs, and lift weights without seeing stars.

And gee, they give you this little card that you can show to airport security when you set the metal detectors off.
