Sex Diversity and Equity Among Fellows of the American Orthopaedic Association

We hypothesized that women are underrepresented among fellows of the American Orthopaedic Association (AOA) relative to their prevalence among faculty at departments of orthopaedic surgery.

Clinical faculty at departments of orthopaedic surgery that are affiliated with residency training programs were analyzed for AOA membership. Participation-to-prevalence ratios (PPRs) were calculated for men and women with AOA membership relative to their prevalence among orthopaedic surgeon faculty. A PPR of <0.8 or >1.2 indicated under- or overrepresentation, respectively. PPR values between 0.8 and 1.2 indicated equivalent representation. Sex disparities in AOA membership were explored by academic rank and orthopaedic subspecialty.

There were 4,310 orthopaedic surgery faculty, and 998 (23.2%) had AOA membership. Overall, women formed the minority of members in the AOA study cohort (11.4%), but they had equivalent representation relative to their prevalence among faculty (10.0%, PPR = 1.14, p = 0.210). In the AOA study cohort, women were the minority at each academic rank, including assistant professor (20.2% versus 79.8%, p < 0.001), associate professor (16.8% versus 83.2%, p < 0.001), and full professor (7.0% versus 93.0%, p < 0.001). However, women had greater representation in the AOA study cohort at each academic rank than would be expected based on their prevalence among faculty, including the assistant (PPR = 1.45), associate (PPR = 1.56), and full (PPR = 1.27) professor levels. Similarly, in the AOA study cohort, women were the minority in each orthopaedic subspecialty, but were only underrepresented in pediatric orthopaedics (PPR = 0.74). Women had greater representation in the AOA study cohort than would be expected by their prevalence among faculty in hand surgery (PPR = 1.51) and orthopaedic sports medicine (PPR = 1.33). In contrast, men had equivalent representation in each orthopaedic subspecialty.

Women form a minority group in the AOA, but they exhibit greater representation in the AOA than would be expected based on their prevalence among faculty at each academic rank, and they have greater representation than men, who exhibit equivalent representation across all academic ranks. Collectively, these results disproved our hypothesis, and suggest that women are participating in the AOA at rates that are greater than their prevalence among faculty.

Equitable participation of women in orthopaedic surgery is necessary to promote diversity and inclusion in the specialty. The AOA may be an important catalyst for future positive diversity and inclusion efforts within orthopaedic surgery.
