The Journal of ISAKOS (JISAKOS) is the official journal of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine. The journal publishes high-quality peer-reviewed review articles from the international community of orthopaedic surgeons and sports medicine physicians. The journal covers important topics that serve to engage and advance the knowledge and treatment of musculoskeletal diseases and disorders among specialists and other interested health professionals.
JISAKOS adheres to the highest standards concerning its editorial policies on publication ethics and scientific misconduct. consent and peer review criteria. The journal follows guidance produced by bodies that include the Committee on Publication Ethics (COPE), the World Association of Medical Editors (WAME), the Council of Science Editors and the International Committee of Medical Journal Editors (ICMJE). To view all BMJ Journal policies, please refer to the BMJ Author Hub policies page.
Every research article, including every submitted article involving human participants, requires a statement of ethical or institutional review board approval within the manuscript text. Furthermore, a formal letter of ethical or institutional review board approval must be uploaded along with the manuscript files at initial submission.
Authors are required to submit a statement that their study obtained ethics approval (or a statement that it was not required and why) and that participants gave informed consent. Our Editors will consider whether the work is morally acceptable as determined by the World Medical Association’s Declaration of Helsinki.
In addition to this, in line with General Medical Council guidelines, an article that contains personal medical information about an identifiable living individual requires patients explicit consent (in the format of a signed BMJ patient consent form) before we will publish it. Furthermore, a formal letter of ethical or institutional review board approval must be uploaded along with the manuscript files at initial submission. Please
To make the best decision on how to deal with a manuscript, JISAKOS needs to know about any competing interests authors may have; this includes any commercial, financial or non financial associations that may be relevant to the submitted article. Authors must download and complete a copy of the ICMJE Conflict of Interest disclosure form.
JISAKOS requires that all advertising and sponsorship associated with the journal does not influence editorial decisions, is immediately distinguishable from editorial content and meets all other BMJ guidelines. Please find more information about competing interests and a link to the form.
We take seriously all possible misconduct. If an Editor, author or reader has concerns that a submitted article describes something that might be considered to constitute misconduct in research, publication or professional behaviour they should forward their concerns to the journal. The publisher will deal with allegations appropriately following ICMJE and COPE guidelines. Corrections and retractions are considered where an article has already been published; corrections, expressions of concern or a retraction notices will be published as soon as possible in line with the BMJ correction and retraction policy.

JISAKOS uses a slightly modified version of Vancouver referencing style (see example below). The style template is available via EndNote. Please make sure that the References are double-spaced and no (automatic) listing formats are used like, for example, bullets or numbers.
JISAKOS Reference Style
List the names and initials of all authors if there are six or fewer; otherwise list the first three and add “et al”. Use one space only between words up to the year and then no spaces. The journal title should be in italics and abbreviated according to the style of Medline. If the journal is not listed in Medline, then it should be written out in full.
JISAKOS publishes original research on surgical and/or non-surgical interventions, diagnostic procedures, rehabilitation, prevention and other topics in the journal’s key fields of interest.
An original article is about 3,000 words long (excluding abstract, figure captions, tables and references) and includes up to 50 references.
The maximum number of tables and/or figures is six. Additional data may be presented as supplementary information, which will be published online at the time of online publication.
The title should contain a concluding statement on the primary finding of the study, expressing the most important finding of this study according to the author.
The abstract is up to 350 words. It contains as headings Objectives, Methods, Results, Conclusion and the level of evidence according to table 1 (end of this document).
For certain studies, like but not limited to laboratory experiments and model simulations, the level-of-evidence statement does not apply. A text box, titled “What are the new findings?”, should follow the abstract and contain 3-4 bullet points summarising the new findings.
The paper contains the sections Introduction, Methods, Results, Discussion and Conclusion. A short introduction suffices if the rationale of the study is obvious, i.e. it may be as short as 3 short paragraphs if that addresses “Why the study was performed”. An extensive literature review will not be accepted. The use of subheadings in the methods, results and discussion is encouraged, thereby itemising different aspects of each respective section.
A Current Concepts Review is invited by the Editor-in-Chief with input from the Editorial Board.
A Current Concepts review addresses a single issue of an intervention or a diagnostic procedure for a certain condition. It contains statements of current knowledge, practice and recent evidence, with references to relevant papers as well as detailed descriptions of surgical techniques, patient management strategies, and/or diagnostic methods as appropriate.
At the end of the Current Concepts Review, authors conclude on the current best practice based on the best available evidence and describe what is required for better supporting the technical choices in the future.
A paper should be about 3,000 words (excluding abstract, figure captions, tables and references) and include up to 50 references. It should include an unstructured abstract of no more than 350 words. The number of tables and figures is limited to eight.
A Current Concepts article must include the following:
The title should contain the topic addressed followed by “:current concepts”.

JISAKOS publishes systematic reviews on surgical and/or non-surgical interventions in the journal’s key fields of interest. Quality reporting is important to JISAKOS and a systematic review must follow the PRISMA guidelines. While systematic reviews will be invited by the Editor-in-Chief with input from the Editorial Board, a manuscript can also be submitted without invitation.
Generally, systematic reviews are 4,000 words (excluding abstract, figure captions, tables and references) and will have 75-100 references. Authors should attempt to synthesise results either quantitatively or qualitatively.
The title should contain a concluding statement on the primary finding of the review followed by either “a systematic review” or “a meta-analysis”.
- Include one or two sentences describing the clinical question or issue and its importance in clinical practice or public health.
Aim or Objective
- State the precise primary objective of the review. Indicate whether the review emphasizes factors such as cause, diagnosis, prognosis, therapy, or prevention and include information about the specific population, intervention, exposure, and tests or outcomes that are being reviewed.
- Describe the information sources used, including summary of the search strategies, years searched, and other sources of material, such as subsequent reference searches of retrieved articles. Methods used for quality assessment and inclusion of identified articles should be explained. Describe the methods of qualitative and quantitative analysis of the data retrieved from the articles.
- The major findings of the review of the clinical issue or topic should be addressed in an evidence-based, objective, and balanced fashion, with the highest quality evidence available receiving the greatest emphasis.
Conclusions and Relevance
- The conclusions should clearly answer the questions posed if applicable, be based on available evidence, and emphasize how clinicians should apply current knowledge.
Level of Evidence
- Add the level of evidence according to table 1 (end of this document).
Immediately following the abstract add a text box containing two sets of bullet points.
- Title: “What is already known”
Contents One or two single sentence bullet points to summarise what is already known about the subject before this review commenced and what has necessitated this review.
- Title: ”What are the new findings”
Contents Two to four bullet points summarising what the new findings are based on the results of the review or meta-analysis.’ Be clear and specific in formulating the bullet points. The total maximum number of bullet points is six.
The body of the manuscript should contain the headers Introduction, Methods, Results, Discussion and Conclusion.
The review should be conducted according to the PRISMA guidelines
For the introduction, methods, results and discussion use the PRISMA checklist as a reference.
Include a flow diagram according to the PRISMA guidelines depicting the flow of information through the different phases of a systematic review. It maps out the number of records identified, included and excluded, and the reasons for exclusions. The PRISMA document can be used for this. The flow diagram should be submitted in editable format (Microsoft Word, Visio or PowerPoint).
A State-of-the-Art Review is invited by the Editor-in-Chief with input from the Editorial Board. It is generally written by a three-author team, with authors drawn from three major regions of the world, to ensure a truly global perspective. The author team can be supplemented by a fourth author that assists in drafting the manuscript.
A State-of-the-Art review contains statements of current knowledge, practice and evidence, with references to relevant and recent papers as well as detailed descriptions of surgical techniques, patient management strategies, and/or diagnostic methods as appropriate.
At the end of each State-of-the-Art Review, authors describe the future perspectives on the development of diagnosis and treatment, given the best available evidence. Authors then elaborate on the basic and applied research required and provide a statement on where the field will be in three to five years.
Papers should be about 6,000 words (excluding abstract, figure captions, tables, text boxes and references) and include up to 100 references. Papers should include an unstructured abstract of no more than 350 words. You should include as many illustrative boxes and tables as necessary. Boxes are not cited within text, but tables are cited. Boxes can include pearls and pitfalls and any other information that is important to call attention to the reader. Likewise, authors are encouraged to include as many figures as necessary to convey the article’s topic.
All State-of-the-Art articles must include the following:
