Introduction: Patellar tendinopathy is one of the main causes of knee pain in athletes and is characterized by degenerative changes, local pain, and functional limitation, which can impact the performance and career length of athletes. Information on patellar tendinopathy has been frequently searched for on online search engines around the world, highlighting the need for a greater understanding of the quality of this information. Objective: To verify the comprehensibility, actionability, readability, comprehensiveness, accuracy, clarity, and quality of the content available on websites located on Google® and Bing® about patellar tendinopathy. Methods: This is a cross-sectional observational study reported in accordance with the STROBE recommendations. The samples were collected from the search databases, and the first 20 websites for each search term in English were selected: “Patellar Tendinopathy” and “Jumper’s Knee” in each search engine, totaling 80 links collected by two independent evaluators. For content analysis, a rubric previously developed based on current scientific evidence was used as a reference; for analysis of comprehensibility and actionability, the online PEMAT questionnaire was used; readability was measured using the Flesch-Kincaid education level; and for analysis of the quality of information about treatment options for patellar tendinopathy, the DISCERN tool was used. Results: Preliminary results are presented in this qualification. The searches resulted in 160 links, of which 30 were included in the final analysis. Results of comprehensiveness, accuracy, and clarity showed that 90.5% of the websites presented information categorized as “inaccurate”/“misleading”. Comprehensibility and actionability results showed that 37.06% of the websites were in accordance with the public's understanding capacity, and 9.06% were adequate for the applicability of the information. Regarding readability, 56.67% of the websites presented a reading difficulty level above that of an 8th grade school student. Conclusion: Preliminary results indicate that online information about patellar tendinopathy lacks precision, clarity, and convergence with scientific evidence. Clinicians should be careful when using information from websites to support their therapeutic approaches for patients with patellar tendinopathy.
