Impact of Sports Medicine and Orthopedic Surgery Rotations on Musculoskeletal Knowledge in Residency.

Introduction Musculoskeletal (MSK) complaints and injuries comprise 18.7% of emergency department visits. However, only 61% of emergency physicians (EP) pass a validated written Freedman and Bernstein MSK examination (FB-MSK). Educational interventions such as a primary care sports medicine (PCSM) rotation aid in MSK residency education. This study utilizes a validated MSK examination to evaluate and compare MSK knowledge acquisition following a traditional orthopedic rotation and a PCSM rotation. Methods Forty-nine interns were recruited to participate in this study over two academic years. The FB-MSK was administered to all participants at the start of residency. Participants were divided into two groups based on their residency sites; one group completed a traditional four-week orthopedic surgery rotation and the second group completed a four-week PCSM rotation. Forty-six of the forty-nine participants were administered the FB-MSK after completion of their rotations. Results Individual post-rotation scores significantly improved regardless of rotation (mean difference 2.78, 0.001; 95% CI 2.05-3.52). The orthopedic surgery group significantly improved (mean difference 2.84, <0.001; 95% CI 1.93-3.73) and the PCSM group significantly improved (mean difference 2.64, =0.002; 95% CI 1.23-4.07). There was no significant difference in pre-rotation scores between the two groups (=0.86; 95% CI -2.13 to 1.79). There was no significant difference in post-rotation scores between the two groups (=0.66; 95% CI -1.98 to 1.26). There was no significant difference in mean score improvement between the two groups (=0.81; 95% CI -1.33 to 1.69). Conclusion This study demonstrates significant MSK knowledge acquisition and no difference in the level of knowledge acquisition after completion of either traditional orthopedic surgery or PCSM residency rotation.
