Prevalence of total hip replacement (THA) in the US population was 0.83% overall in 2010; by age 80 it reached 5.26%. Women had higher prevalence than men at all ages.
“"[Paraphrase from abstract — full text paywalled] The 2010 prevalence of total hip and total knee replacement among the total U.S. population was 0.83% and 1.52%, respectively, with prevalence being higher among women than among men and increasing with age, reaching 5.26% for total hip replacement and 10.38% for total knee replacement at eighty years."”
Calculation notes
Prevalence at age 80 = 5.26% for THA. This represents cumulative incidence through age 80 among the US population. Because THA incidence continues after age 80 and because annual THA volumes have increased since 2010, the lifetime risk from age 18 to death is estimated at ~9%. The Olmsted County cohort is a well-characterized, racially diverse population that closely tracks US national demographics.
Independence note: Maradit Kremers 2015 used the Rochester Epidemiology Project (Olmsted County, MN) population-based medical records linkage — entirely independent of the AAOS registry administrative data, which captures only subset of procedures at participating centers.

Prevalence of total knee replacement (TKA) in the US population was 1.52% overall in 2010; by age 80 it reached 10.38%. Women had higher prevalence than men at all ages.

Calculation notes
TKA prevalence at age 80 = 10.38% for the US population (Olmsted County population-based cohort). Because TKA incidence continues beyond age 80 and annual volumes have risen since 2010, the lifetime risk from age 18 to death is estimated at ~10%. TKA prevalence substantially exceeds THA (10.38% vs 5.26% at age 80), consistent with the higher incidence of knee vs hip OA.
Independence note: Maradit Kremers 2015 used the Rochester Epidemiology Project (Olmsted County, MN) population-based medical records linkage, independent of AAOS registry administrative data. The two data systems measure the same procedures through entirely different pipelines.
