Learning on a Limb: An outreach module to engage high school students in orthopaedics.

Orthopaedic researchers need new strategies for engaging underrepresented minority (URM) students. Our field has demonstrated noticeable gaps in racial, ethnic, and gender diversity, which inhibit our ability to innovate and combat the severe socioeconomic burden of musculoskeletal disorders. Towards this goal, we designed, implemented, and evaluated Learning on a Limb (LoaL), an orthopaedic research outreach module to teach URM high school students about orthopaedic research. During the 4-h module, students completed hands-on activities to learn how biomechanical testing, microcomputed tomography, cell culture, and histology are used in orthopaedic research. Over 3 years, we recruited 32 high school students from the Greater Philadelphia Area to participate in LoaL. Most participants identified as racial/ethnic or gender minorities in orthopaedic research. Using pre/post-tests, we found that students experienced significant learning gains of 51 percentage points from completing LoaL. In addition to teaching students about orthopaedic research, post-survey data demonstrated that participating in LoaL strongly influenced students' interest in orthopaedic research and scientific confidence. Several students acted on this interest by completing summer research experiences in the McKay Orthopaedic Research Laboratory at the University of Pennsylvania. LoaL instructors also benefited by having the opportunity to "pay it forward" to the next generation of students and build community within their department. Empowering institutions to host modules like LoaL would synergistically inspire URM high school students and strengthen community within orthopaedic departments to ultimately enhance orthopaedic research innovations.
