Hip implants lasting longer

May 18, 2009 They found that total hip replacements that use components that don't have cement can last 20 years, or twice as long as the previous versions.

Earlier versions used a special cement to help secure the replacement joint to the patient's bones, but these failed more often , especially after 10 years use.

Instead of cement, the new implants use a porous material to which bone can fuse to create a stronger, longer lasting bond.

Researchers say this is good news for active, younger people who require hip replacements.
