Duplicate publication in orthopaedic journals may further an author's academic career but this is at the cost of both scientific integrity and knowledge. Multiple publications of the same work increase the workload of editorial boards, misguide the reader and affect the process of meta-analysis. We found that of 343 'original' articles published in the Journal of Bone and Joint Surgery in 1999, 26 (7.6%) had some degree of redundancy.
The prevalence of duplicate publications in the orthopaedic literature appears to be less than that in other surgical specialties but it is still a matter of concern. It is the author's responsibility to notify the editor of any duality when submitting a paper for publication.
