NOt me.
But I have an elderly neighbor who had a 'partial" knee replacement done a few years ago.
80 yrs old then ( 83 now and very energetic. She drives off to do something every day. Even has a 75 yr old "boyfriend"

come over for lunch)
One week after the Partial Knee Replacement surgery she was out here walking around.. no cane or anything!
She says "The pain is gone" that she had before the surgery.
She is very happy she did it.
But she does say she can't ride an excercise bike because of her knees
(one full replacement done ages ago and the one partial replacement)
