Lifetime risk of total hip replacement surgery and temporal trends in utilization: A population-based analysis

Abstract

Objective To investigate lifetime risk of total hip replacement (THR) surgery in the state of Victoria, Australia and to describe temporal trends in THR incidence. Methods We analyzed a retrospective population-based longitudinal cohort of patients who received a primary THR in Victoria from 1998-2009. The factors potentially contributing to changes in lifetime risk were also examined, including temporal changes in THR incidence according to health care setting (public versus private), socioeconomic status, and geographic location (regional versus metropolitan). Results We identified 45,775 patients receiving THR over the time period. For a woman age 20-29 years, the mortality-adjusted lifet..
