Purpose

This study was carried out to assess the quality of information available on YouTube regarding femoroacetabular impingement (FAI).

Methods

YouTube was searched on September 7, 2013 using the search terms FAI, femoroacetabular impingement, and hip impingement. Analysis was restricted to the first 3 pages of results for each search term. English language was a prerequisite for inclusion. Videos were evaluated by 2 independent reviewers (M.G.M., D.J.H.) using novel scoring checklists for diagnosis and treatment of FAI. Interobserver reliability analysis was evaluated using the intraclass correlation coefficient (ICC). Videos were grouped according to quality assessment score, and the group means were analyzed for differences in video characteristics using the analysis of variance (ANOVA) model. Videos were characterized by the source of content.

Results

After filtering 1,288,324 potential videos, 52 videos were identified and included for analysis. The mean video quality assessment scores were 3.1 for diagnosis and 2.9 for treatment (maximum score = 16). No videos were scored as excellent (quality assessment score > 12). Effective resources included 3 videos on diagnosis and one video on treatment. No statistically significant differences were found between high- and low-scoring videos for duration, days online, views per day, likes, likes per day, likes per view, dislikes, or likes-dislikes difference for either diagnosis or treatment (P > .05 for all). The source of most of the videos was educational (67%), and most of these included physicians (66%).

Conclusions

Patients searching YouTube for videos pertaining to FAI will be presented with a sizeable repository of content of overall low quality. As such, physicians need to recognize the potential influence of YouTube videos on patients' preconceptions of their conditions and the effect on the physician-patient consultation. This review highlights the need for evidence-based, comprehensive educational videos addressing FAI diagnosis and treatment.

Level of Evidence

Search Strategy

YouTube was searched on September 7, 2013 for videos containing information relating to FAI using the following search terms: (1) FAI, (2) femoroacetabular impingement, and (3) hip impingement. The standard YouTube search setting of “relevance” was used. Search results were restricted to the first 3 pages of results on the assumption that users would not look beyond the third page of results for video information. Videos were excluded if they were non-English or were not related to pathologic

Results

The search identified 1,288,324 videos (search term FAI = 1,280,000 videos, femoroacetabular impingement = 674 videos, and hip impingement = 7,650 videos). After limiting the review to the first 3 pages of search results, 159 videos were identified. After applying exclusion criteria, 52 videos were included for analysis (Fig 1). Reasons for exclusion included 21 videos duplicated by different search terms, 39 non-English videos, 19 videos not related to pathologic conditions of the hip, and 28

Discussion

Patients searching YouTube for information on FAI will be presented with considerable content volume that is of wide ranging but overall low quality. According to our assessment scoring, no videos were found to score within the excellent group for diagnosis or treatment. There were 3 videos and one video, respectively, that were determined to be very useful for diagnosis and treatment information. Most videos were found to be moderately useful or somewhat useful, and a minority were not useful.

Conclusions

Patients searching YouTube for videos pertaining to FAI will be presented with a sizeable repository of content of overall low quality. As such, physicians need to recognize the potential influence of YouTube videos on patients' preconceptions of their conditions and the effect on the physician-patient consultation. This review highlights the need for evidence-based comprehensive educational videos addressing FAI diagnosis and treatment.
