Social Media Use Among Arthroscopic and Orthopaedic Sports Medicine Specialists Varies by Subspeciality

PURPOSE: To evaluate active social media use among members of the Arthroscopy Association of North America (AANA) and investigate differences in social media use based on joint-specific subspecialization. METHODS: The AANA membership directory was queried to identify all active, residency-trained orthopaedic surgeons within the United States. Sex, practice location, and academic degrees earned were recorded. Google searches were conducted to find professional Facebook, Twitter, Instagram, LinkedIn, and YouTube accounts along with institutional and personal websites. The primary outcome was the Social Media Index (SMI) score, an aggregate measure of social media use across key platforms. A Poisson regression model was constructed to compare SMI scores across joint-specific subspecializations: knee, hip, shoulder, elbow, foot & ankle, and wrist. Specialization in the treatment of each joint was collected using binary indicator variables. Since surgeons were specialized in multiple groups, comparisons were made between those who do and do not treat each joint. RESULTS: In total, 2,573 surgeons within the United States met the inclusion criteria. 64.7% had ownership of at least 1 active account, with an average SMI score of 2.29 ± 1.59. Western practicing surgeons had a significantly greater presence on at least 1 website than those in the Northeast (P = .003, P < .001) and South (P = .005, P = .002). Social media use by knee, hip, shoulder, and elbow surgeons was greater relative to those who did not treat those respective joints (P < .001 for all). Poisson regression analysis demonstrated that knee, shoulder, or wrist specialization was a significant positive predictor of a greater SMI score (P ≤ .001 for all). Foot & ankle specialization was a negative predictor (P < .001), whereas hip (P = .125) and elbow (P = .077) were not significant predictors. CONCLUSIONS: Social media use widely varies across joint subspecialties within orthopaedic sports medicine. Knee and shoulder surgeons had a greater social media use than their counterparts, whereas foot & ankle surgeons had the lowest social media use. CLINICAL RELEVANCE: Social media is a vital source of information for both patients and surgeons, providing a means for marketing, networking, and education. It is important to identify variations in social media use by orthopaedic surgeons by subspecialty and explore the differences.
