ABSTRACT Objective: This study aims to assess the quality of articles published in the leading orthopedic surgery journals, by measuring the relation between the impact factor and the number studies with a high level of evidence. Methods: A literature review was performed of articles published in four previously selected journals. A score of journal evidence (RER - Relation between Randomized clinical trials and Systematic reviews) was calculated, considering the number of RCTs and SR published and the total number of full-text articles. Results: The selected journals were JBJS-Am, ASMJ, BJJ-Br and Arthroscopy, with Impact factors of 5.280, 4.362, 3.309 and 3.206 respectively in 2015. In the study, the RER Scores, in the same order, were 9.408, 6.153, 7.456 and 7.779. Conclusion: The journal JBJS-Am is the best available source of information on orthopedic surgery from this point of view. It has the highest Impact Factor and clearly the highest RER Score. On the other hand, we could conclude that the number of published RCT and good quality SR is very low, with less than 10% of all the articles. Level of evidence III, Analyses based on limited alternatives and costs, and poor estimates.
