  1. ① Registration of Clinical Trial Research
     It is recommended that any research that deals with a clinical trial be registered with a primary national clinical trial registration site, such as https://cris.nih.go.kr/, or other sites accredited by the WHO as listed at http://www.who.int/ictrp/en/.
  2. ② Conflict of Interest
     The corresponding author of an article is asked to inform the editor of the authors’ potential conflicts of interest possibly influencing their interpretation of data. A conflict of interest may exist when an author (or the author’s institution or employer) has financial support from pharmaceutical or commercial companies or political pressures from interest groups or personal relationships that could influence (or bias) the author’s decisions, work, or manuscript. A potential conflict of interest should be disclosed in the manuscript even when the authors are confident that their judgments have not been influenced in preparing the manuscript. Such conflicts may be financial support or private connections to pharmaceutical companies, political pressure from interest groups, or academic problems (e.g., employment/affiliation, grants or funding, consultancies, stockownership or options, royalties, or patents filed, received, or pending). If the study was sponsored by a third party, authors should describe the role of the study sponsor in study design; collection, analysis, and interpretation of data; writing the report; and the decision to submit the report for publication. Where authors have no competing interests, the statement should read “No potential conflict of interest relevant to this article was reported.”
  3. ③ Statement of Informed Consent
     Copies of written informed consent and institutional review board (IRB) approval for clinical research should be kept. If necessary, the editor or reviewers may request copies of these documents to resolve questions about IRB approval and study conduct. In addition, for studies conducted with human subjects, the method by which informed consent was obtained from the participants (i.e., verbal or written) also needs to be stated in the Methods section.
  4. ④ Patient Photographic and Videographic Consent
     Patients introduced in the manuscripts should be informed and aware that their photographs, videotapes, and other images (imaging records) will be released by the authors, and the authors should attach the Authorization and Release Form available at the Hip & Pelvis website (https://submit.hipandpelvis.or.kr/submission/Login.html/ or https://hipandpelvis.or.kr/) including each patient’s signature.
  5. ⑤ Statement of Human and Animal Rights
     All human and animal investigations must be conducted according to the principles expressed in the Declaration of Helsinki (2013; https://www.wma.net/).

After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Copyright assignment must be completed by every author.
  8. ⑧ Originality and Duplicate Publication
     All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. No part of the accepted manuscript should be duplicated in any other scientific journal without the permission of the Editorial Board. The duplication will be checked through crosscheck (https://app.ithenticate.com/) or eTBLAST (http://etest.vbi.vt.edu/etblast3/) before submission. If duplicate publication related to the papers of this journal is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutes will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, illustrations, and tables.
  9. ⑨ Secondary Publication
     It is possible to republish manuscripts if the manuscripts satisfy the conditions of secondary publication of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.
• 9) The editorial board will continuously work for monitoring / safeguarding research and publication ethics: Registration of Clinical Trial Research / Conflict of Interest / Statement of Informed Consent / Patient Photographic and Videographic Consent / Statement of Human and Animal Rights / Copyright and Licensing / Authorship / Plagiarism / Originality and Duplicate Publication / Secondary Publication. In case of unjustifiable act in the research and publication ethics, it shall decide whether to take disciplinary action or not after thorough investigation based on various standardized guidelines (COPE) by the editorial ethics committee. The decided contents shall be reported to the board of directors in the Korean Hip Society and the board of directors shall announce the fact after deciding the final consideration on the discipline disposition reported to the ethics committee.

Upon receiving a paper, the editor-in-chief sends the paper, after deleting the name and title of the author, to three or more professionals in the relevant field of the paper, and asks them to assess the ingenuity, importance, level of contribution and form of manuscript. Based on the results of the professionals’ review, the editor-in-chief makes a decision using four ratings: ‘accept as it is’, ‘accept after minor revision’, ‘review after major revision’, and ‘reject’. According to this decision, the editor-in-chief may recommend the authors to revise and supplement. Upon completion of the revision based on the recommendations, the authors must re-submit the paper through the online submission system. In this case, the authors should submit a revision response file as an attachment to the revised edition. When submitting a revised version, the revisions should be added a point-by-point reply to the reviewers’ comments and also highlighted the changes to the manuscript by using yellow highlighting. The process of examination and revision of the paper is repeated until the publication is accepted or rejected, or authors decide to withdraw the publication. The final decision on the publication and the order to proceed with the publication are made by the editor-in-chief. Unless a special consideration is made, the first review on the paper is conducted within 2 weeks. If the answers to the editors’ comments and the revised file are not submitted by the author within 90 days after receiving the recommendation letter from the editor-in-chief, the case is assumed to be cancelled, and review is terminated.

The publication fee is free. The reprint cost is US \$30 per 30 copies. For color printings, US \$100 per color page is charged to authors regardless of the membership. The publication cost is subjected to change according to the society’s financial situation.

• 1) Abstract
  Abstract is prepared in English on separate page. The length of the abstract is restricted up to 250 words.
