Cementless hip stem produces high survival rates during hip arthroplasty
Despite high ages and osteopenic changes, use of a cementless hip stem during hip arthroplasty demonstrated high survival rates, according to study results.
Researchers reviewed 250 total hip arthroplasties (THAs) in 236 patients performed using a cementless hip stem between 1987 and 1990. Patients’ average age at index surgery was 58.1 years, and average follow-up occurred at 22.8 years.
Overall, 81 patients died and nine were lost to follow-up, according to the researchers.
Study results showed a Kaplan Meier survival rate of 95% as a result of 11 stem revisions. Patients’ average Harris Hip Score was 81 points.
In an age-related subanalysis, the researchers found no significant differences in outcomes for patients older or younger than 60 years.
