The history of the Caramelldansen phenomenon, researched in exacting detail. Uma uma! - Neil Creek

"Because titanium is no good in joints. Titanium on titanium is painful and grinds up into powder, which acts like grit, making it wear down faster. Teflon is used as a contact point for prosthetic joints, but over time it wears out too. My wife has juvenile-onset rheumatoid arthritis, and had both her knee joints replaced 10 years ago. Now the teflon is wearing out, because it's turning to mush. She's in a lot of pain from the joints now, with significantly reduced mobility, and is at risk of the teflon coming into direct contact, as well as accidental dislocation. If this ceramic could be used to replace teflon in prosthetic joints, it might possibly extend their lifespan significantly. One major problem I can think of though, is that I doubt a ceramic would have the same shock-absorbing properties as teflon. Some kind of composite material might be a good solution." - Neil Creek
