Positioning hip implants poses a number of challenges, particularly in terms of getting bone and implant contact right. While experimental testing can be costly, image-based modelling can be very effective at predicting the best and worst positions for implants.

To me, that metal - on - metal had large friction, especially with the newest designs, it was clear from the old Sir Charnley studies in Leeds in 1950s published in his gold book.
Anyway, when I looked at ceramic on ceramic joints, I also found evidence of increased friction. Maybe ceramic debris is less toxic?
Please comment. What can we do outside USA to improve the situation?
