Although studies have revealed high readability levels of orthopedic patient education materials, no study has evaluated sports medicine-related patient education materials. We conducted a study to assess the readability of sports medicine-related patient education materials from the American Academy of Orthopaedic Surgeons (AAOS) and the American Orthopaedic Society for Sports Medicine (AOSSM). All sports medicine patient education articles available online in 2012 from the AAOS and the AOSSM, including the Stop Sports Injuries Campaign (STOP), were identified, and their readability was assessed with the Flesch-Kinkaid (FK) readability test. Mean overall FK grade level of the 170 articles reviewed (104 from AAOS, 36 from AOSSM, 30 from STOP) was 10.2. Mean FK levels for the 3 sources were 9.5 (AAOS), 11.0 (AOSSM), and 11.5 (STOP) (P = .16). Fifteen (8.8%) of the 170 articles had a readability level at or below eighth grade (average reading level of US adults); only 2 (1.2%) of the 170 articles were at or below the recommended sixth-grade level. The majority of sports medicine-related patient education materials from AAOS and AOSSM had reading levels higher than recommended, indicating that the majority of the patient population may find it difficult to comprehend these articles.
