   Prevalence of Total Hip and Knee Replacement in the United States

   See all 2 Likelier entries citing this source →

   Thống kê

   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.

   Trích đoạn

   “"[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." ”

   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.

   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.

   Projecting Lifetime Risk of Symptomatic Knee Osteoarthritis and Total Knee Replacement in Individuals Sustaining a Complete Anterior Cruciate Ligament Tear in Early Adulthood

   Thống kê

   Lifetime risk of total knee replacement was 22.3% for adults with prior ACL tear and meniscal injury combined, compared to 6.0% for those without knee injury. ACL injury without meniscal tear was associated with 8.0% (surgical) to 8.9% (non-operative) lifetime TKR risk; the higher 16–17% figures for that cohort are the lifetime risk of symptomatic knee osteoarthritis, not of total knee replacement.

   Trích đoạn

   “"[Paraphrase from full text] The estimated lifetime risk of symptomatic knee osteoarthritis was 34.2% for cohorts with ACL injury and meniscal tear, compared to 13.5% for no-injury cohorts. The risk of total knee replacement was 22.3% in the ACL and meniscal tear cohort versus 6.0% in the no-injury cohort — roughly 3.7 times greater." ”

   Used to quantify the personal_factor_multiplier for prior ACL/meniscal injury. 22.3% TKR risk for ACL + meniscal tear vs 6.0% baseline (no injury) = approximately 3.7× relative risk on the source's own cohort estimates. At the population baseline of ~10% lifetime TKR, the absolute risk for those with ACL + meniscal injury approaches ~20–22%.

   Driban et al. used a simulation model based on existing epidemiological cohort data (Framingham OA Study, Johnston County OA Project), independent of the Olmsted County prevalence data used by Maradit Kremers.

   AJRR captured over 3.7 million validated primary and revision THA and TKA procedures from 2012 to 2023; TKA is the majority procedure type at participating centers.

   Trích đoạn

   “"The 2024 AJRR Annual Report contains 3,715,320 validated primary and revision THA and TKA procedures performed during years 2012 to 2023, with primary THA comprising 32.4% of procedures captured. The AJRR remains the largest orthopaedic and joint arthroplasty registry in the world by annual procedure volume." ”

   If primary THA is 32.4% of procedures, then TKA + revisions account for 67.6%. Primary TKA is a substantially larger share of total procedures than THA, consistent with the higher population-level TKA prevalence (10.38% vs 5.26% at 80). Used to confirm high annual volumes and the TKA > THA utilization ratio.
