Readability of Sports Injury and Prevention Patient Education Materials From the American Academy of Orthopaedic Surgeons Website

INTRODUCTION: The purpose of this study is to evaluate the readability of 114 Sports Injury and Prevention patient education materials provided by the American Academy of Orthopaedic Surgeons (AAOS). METHODS: We evaluated all articles written in English posted under the Sports Injury and Prevention section of the AAOS website using readability software to compute six readability scores, which we compared with the eighth-grade level using a two-tailed one-sample Student t-test. RESULTS: The mean reading grade level calculated by each readability test was markedly higher than the eighth-grade level. We reported mean ± SD for each test: Flesch-Kincaid grade level (8.95 ± 1.51; P < 0.001), Simple Measure of Gobbledygook (11.53 ± 1.18; P < 0.001), Coleman-Liau index (11.16 ± 1.33; P < 0.001), Gunning Fog index (11.06 ± 1.63; P < 0.001), New Dale-Chall (9.49 ± 1.66; P < 0.001), and FORCAST formulas (10.96 ± 0.60; P < 0.001). DISCUSSION: This study shows that patient education materials provided by the AAOS concerning sports injury and prevention are written at a readability level too high for patients to understand. On average, patient materials are written at least 2.5 grade levels higher than national recommendations. Only 7% of the 114 articles had readability scores in line with national recommendations. These findings indicate a need for revised patient education materials geared toward bringing the readability level down to the recommended eighth-grade level.
