This study uses 14 years of Nationwide Inpatient Sample data (1990-2003) and Poisson regression to project U.S. primary and revision hip and knee arthroplasty demand through 2030. It answers how much arthroplasty volume will grow — and whether constant or time-varying prevalence models best capture that growth. Projections are stratified by age, sex, race/ethnicity, and census region.
