Risk Factors for Total Knee Arthroplasty Aseptic Revision
Section snippets
Background
Total knee arthroplasty (TKA) outcomes are dependent on a variety of factors, which include the patient [1], the surgeon [2], type of implant [3], and the hospital 2., 4., challenging the ability of researchers to comprehensively study variables affecting TKA. Tertiary medical centers may provide detailed information on patient and surgical factors, but the patient populations, and surgeon experience, may not be representative of the situation in the United States. In addition, sample sizes may
Study Design, Inclusion Criteria, and Data Collection
A retrospective analysis of a prospectively followed cohort of primary TKAs was conducted using data from a community based Total Joint Replacement Registry (TJRR). All primary TKAs, with any diagnosis, registered from 4/1/2001 to 12/30/2010 were included. Unicompartmental procedures, bi-compartment procedures, patella-femoral procedures, and procedures performed with constrained and hinged implants were excluded. Data collection, participation, and coverage for the TJRR, used to identify the
Results
A total of 64,017 primary TKA cases, followed for a median time of 2.9 years (interquartile range 1.2–4.9 years), were included in the analysis. Patients were predominantly female (62.6%), white (71.0%), with diagnosis of osteoarthritis (97.2%), and obese (56.5% had BMI ≥ 30 kg/m2). The mean age was 67.3 years old (SD = 9.5) and prevalence of diabetes was 26.3%. The implants were cemented in 91.4% of the cases, 12.2% of the cases had high-flex designs, and 86.4% of the cases had CoCr on conventional
Discussion
TKA is a successful and widely performed procedure for the treatment of end-stage knee arthritis. The cumulative incidence of aseptic revision of our study sample of 64,017 patients was 1.3% and the revision rate/100 years of observation time was 0.4. Multivariable regression models identified specific patient, implant, and surgical factors associated with risk of aseptic revision.
The outcomes of TKA are affected by a variety of patient, implant and surgical factors. The current investigation

Racial and Ethnic Disparities in Total Joint Arthroplasty Care: A Contemporary Systematic Review and Meta-Analysis
2023, Journal of ArthroplastyCitation Excerpt :Spanning from 1994 to 2021, articles included in this review were comprised of 457-27,656,346 White, Black, Hispanic, Asian, American Indian/Alaska Native (AIAN), and Pacific Islander (PI) patients who had mean ages ranging from 57 to 77 years. Studies evaluated rates of utilizations [3,4,15–30], complications [3,4,31–42], mortalities [3–5,22,23,31–39,41–47], LOS [3–5,32,33,35,37,39,41,42,48–59], discharge dispositions [4,5,33,34,39,48,49,54,56–64], readmissions [5,33–35,37,39,42,43,46,47,49,50,56,57,59,64–71], and reoperations [32,33,35,37,39,42,43,46,56,57,59,72–74] for THA and TKA to determine any racial and ethnic disparities. A summary of study characteristics is provided in Table 1.
