Probably better! Long-term studies over a 30-year period of time show uncemented implants actually have less chance of loosening.
In one study of more than 6,500 total hip replacements (THRs), not one uncemented THR came loose. The cemented implants have a tendency to loosen during the second decade.
The increased survivorship for uncemented implants and improved durability have made it the new gold standad for THR.
