my mum had one knee done 2 years ago and still gives her pain when walking...can't kneel when gardening...She is very frustrated...but living on...much exercise and physioThat's an exhibit I would gladly browse. Here in the future, browsing museums is one of those pleasures I can enjoy again, what with knees I can walk on(unsolicited advice: if any need two full knee replacements, do both at the same time. If you do one, you will not wish to repeat the experience for the other. Then you'll be left with one good knee and one bum knee. And a lot of cussing.)
