The use of online search engines for health information is becoming common practice. We analyzed Google search queries to identify the most frequently asked topics and questions related to lateral epicondylitis ("tennis elbow") and the Web sites provided to address these questions.

METHODS

Four search terms for lateral epicondylitis were entered into Google Web Search. A list of the most frequently asked questions along with their associated Web sites was extracted and categorized by 2 independent reviewers.

RESULTS

A total of 400 questions were extracted with 168 associated Web sites. The most popular question topics were related to indications/management (39.0%), risks/complications (19.5%), and the ability to perform specific activities (18.8%). Frequently asked questions had to do with the duration of symptoms, self-management strategies (eg, brace use and self-massage), and the indications for surgery. The most common Web sites provided to address these questions were social media (27.5%), commercial (24.5%), academic (16.5%), and medical practice (16.3%).
