  • Limit use of the verb “to be”
  • Avoid noun forms of verbs (nominalizations)
  • Limit noun strings (nouns modifying nouns)
  • Put new and important information toward the end of sentences


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.

Original Research

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.

Abstract (Structured)

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.

Main Body

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.

Current Concepts Review

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”.

Abstract (Unstructured)

Clinical problem statement, current diagnostic and therapeutic methods, available evidence and current unsolved issues. The abstract should be complete, concise and attractive to read.

  • Outline of the clinical problem
  • References to previous reviews, state-of-the-art and/or current concepts articles
  • The topic covered by this article
  • Include informative subheadings to separate different subtopics
  • Figures illustrating (special) diagnostic procedures and/or surgical techniques or other interventions with explanatory text are preferred over text-only descriptions.
  • Summarise the major issues and solutions
  • Discuss the current (lack of) evidence
  • If applicable, describe alternative approaches with references to relevant publications
  • Discuss the future perspectives
Additional Material

The online version of the Current Concepts article may contain supplemental material, like descriptions, photos and materials detailing the specific procedures as described in the article.

Mandatory Text Boxes

Include two text boxes:

  1. Title: “Current Concepts”
    Contents This box contains bullet points containing the enumeration of the current concepts as described in the article

    Contents Describe future perspectives on the topic of the article. Elaborate on the research that is required to reach the formulated goals.

Systematic Review

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”.

Abstract (Structured)
  • 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.
Evidence Review
  • 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).
Bullet Points

Immediately following the abstract add a text box containing two sets of bullet points.

  1. 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.
  2. 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.

PRISMA Guidelines

The review should be conducted according to the PRISMA guidelines


For the introduction, methods, results and discussion use the PRISMA checklist as a reference.

Flow Diagram

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).

State-of-the-Art Review

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:
