Women are underrepresented as applicants to and trainees of orthopaedic surgery residencies. Factors that attract women to or deter them from orthopaedic surgery have been previously published; however, there has been no analysis of the programs that train high percentages of female residents and the factors that differentiate them from programs that have low percentages of women. The purpose of this study was to identify and compare these factors between programs with high and low percentages of female residents.
