My problems stem from a broken leg suffered as a high-school freshmen (compound fracture, both bones just above left ankle). When set, that left foot was angled about 5 degrees more "out" than the right one. I thought even then that when I got older I would have joint problems. One of the few times I wished that I had been wrong. When I hit 65, things started going sour (74 now). Thought sure I was headed for knee replacement. So far, WBV seems to have stalled (and even reversed) the deterioration.
I’ve known a lot of guys over the last couple of years at my old club who had knee replacements.
They’re usually out for 6 months to a year. But they do recover and come back.
So it looks like the state of the art for knee hip and shoulder replacements has arrived at a point where much of the original mobility can be restored
