The internet is a frequently utilized resource to acquire health information. This study aims to examine the readability and quality of online information pertaining to total ankle arthroplasty (TAA). “Ankle arthroplasty” OR “ankle replacement” was queried in three search engines, with the first 3 pages of results identified. The readability of sites was calculated using six readability algorithms: Flesch-Kincaid grade level, Flesch Reading Ease, Gunning Fog, SMOG, Coleman-Liau index, and Automated Readability Index. Quality was assessed using the JAMA benchmark, Global Quality Score (GQS), and DISCERN instrument. A total of 62 relevant sites were analyzed. Sources were primarily physician-sponsored (50%) or academic (31%) websites. The mean readability indices were above the recommended sixth grade reading level, with an average grade level of across scoring tools of 13.22 ± 2.07. No sites were at or below a sixth grade reading level. Quality ratings were subpar across assessment tools: JAMA = 1.9 ± 1.0 (range, 1–4) out of 4; GQS = 3.4 ± 1.0 (range, 1–5) out of 5. DISCERN = 54.0 ± 11.2 (range, 31–75) out of 80. The readability and quality of online information regarding ankle arthroplasty is not optimal for the average patient, with improvement valuable in cultivating shared decision-making.
