In response to the new clinical decision-making approach called evidence-based medicine, several publications nowadays include a section stating the level of evidence of the study in order to make it easier for readers to select the papers that are most relevant to them on a specific medical topic.

Moreover, and even if this cannot be required of other orthopedic surgery journals to which we usually submit our manuscripts, we think it might be advisable to carry out a self-criticism exercise of our work in order to assess its genuine quality and significance. To do this, we believe it is extremely important to know the standardized ranking systems and the publication guidelines for different kinds of studied that are commonly used since these can help us apply the most appropriate methodology in each case and make it easier for the reader to assimilate the text, thereby contributing to the enhancement of the scientific quality of our project. This review paper discusses the hierarchies and levels of evidence most frequently employed in the field of orthopedic and trauma surgery, as well as the basic requirements that must be fulfilled by scientific manuscripts.
