Background: The increased emphasis on reimbursement, diversity, and burnout in hip and knee arthroplasty necessitates a foundational understanding of the surgeon workforce. The purpose of the study was to cross sectionally survey a representative sample of the AAHKS surgeon membership on the subject of salary, practice patterns, and demographic factors to establish a baseline framework for future advocacy efforts and initiatives. Methods: An online survey was sent to AAHKS members between December 20, 2022 and January 19, 2023. Surgeon demographic data, experience, practice geography and type, and annual case volume were solicited. Univariate and multivariate analyses were performed to describe the association of respondent characteristics with reported salary directly from patient care, as well as indirect revenue streams. Results: A total of 730 AAHKS members responded to the survey. The largest proportion of surgeons performed 251-400 cases annually (36%); 81% (n = 592) and 93% (n = 679) of respondents identified as white and male, respectively. Case volume was the primary determinant for surgeon salary, followed by practice type, years in practice, and gender. After controlling for confounding variables, multivariate analyses revealed the direct salary of women surgeons was 14.4% less than men [95% confidence interval, 0.4%-28.3%]. When considering indirect revenue, the gender pay gap widened. Salary was not associated with reported hours worked per week, geographic location, or ethnicity. Conclusions: Salary is an important but underdiscussed subject that reflects the realities of our culture and value system in medicine. A direct relationship between salary and modifiable variables like case volume is clear. However, after controlling for confounders, women arthroplasty surgeons still earn 86 cents on the dollar compared to their male colleagues from direct surgical revenue.
