The purpose of this study was to utilize the American Board of Orthopaedic Surgery (ABOS) Part-II Case List database to (1) define the practice patterns of sports medicine-trained ABOS Part- II Oral Examination Candidates and (2) describe the frequency and practice patterns of individuals who are dual fellowship-trained sports medicine candidates.

The ABOS Part-II Case List database was utilized to define all cases submitted by 3,298 applicants indicating completion of a sports medicine fellowship between January 1, 2003, and January 1, 2020. Cases were classified by subspecialty category and case type. The frequency and practice patterns of candidates pursuing additional fellowship training (i.e., “dual fellowship-trained”) were recorded. Descriptive statistical methods were used to describe the annual and overall procedure volume and candidate case mix. Trends in the relative frequency of cases performed and fellowship training patterns were determined using linear regression analysis.

On average, sports medicine-trained candidates submitted 100.6 cases for review during the 6-month case collection period: 59.0 (58.6%) sports medicine/arthroscopy cases, 29.3 (29.1%) trauma/general cases, 4.5 (4.5%) adult reconstruction cases, and 7.8 (7.8%) “other” cases per candidate. Although candidates performed fewer total (r2 = 0.84, p < 0.001) and sports medicine/arthroscopy (r2 = 0.85, p < 0.001) cases over the study period, the proportion of sports medicine/arthroscopy cases did not change over the study period (p = 0.18). Dual fellowship training was indicated by 333 individuals (10.1%). The number of dual fellowship-trained candidates pursuing additional fellowship training in pediatrics and adult reconstruction increased over the study period, and the number of dual fellowship-trained candidates pursuing additional fellowship training in trauma decreased over the study period.

Early-career sports medicine candidates are likely to perform >40% of cases outside of the sports medicine subspecialty. Sports medicine trainees are increasingly likely to pursue a second fellowship in pediatrics or adult reconstruction.
