Metal hips have a 'higher failure rate' say researchers

Metal-on-metal total hip replacements have a much higher failure rate than other options and "should not be implanted", say researchers.

They said data from the world's largest register of hip implants provided "unequivocal evidence" of the failure rate.

All replacements have a risk of failure, such as the new joint coming loose, dislocating or through wear and tear. This study, published in The Lancet, showed some fail far more than others.
