Abstract

Introduction:
In the field of orthopedic surgery, highly impact journals like Journal of Bone and Surgery (JBJS-Am) and Clinical orthopedics and Related Research (CORR) publishing the LOE for their manuscript. JBJS-Am started to publish the level of evidence (LOE) for all manuscript since 2013.
Results:
310 articles were reviewed. Country of origin for these, were twelve different countries including Iran. International articles consistently increased from 23 % of all published articles in 2013 to 47% in 2016. Overall one- third of articles came from USA and Europe in this period and at the last year, this proportion exceeds 41 %.
Discussion:
Publishing LOE and the study type helps the reader to imagine the estimated quality of the research presented before starting to read . The aim of this study was to determine the level of contribution of international researchers and also detect any possible progress in LOE of publications over the past four years in ABJS.
