More information.

    Declaration of Generative AI in Scientific Writing

    The below guidance only refers to the writing process, and not to the use of AI tools to analyse and draw insights from data as part of the research process.

    Where authors use generative artificial intelligence (AI) and AI-assisted technologies in the writing process, authors should only use these technologies to improve readability and language. Applying the technology should be done with human oversight and control, and authors should carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete or biased. AI and AI-assisted technologies should not be listed as an author or co-author, or be cited as an author. Authorship implies responsibilities and tasks that can only be attributed to and performed by humans, as outlined in Elsevier's AI policy for authors.

    Authors should disclose in their manuscript the use of AI and AI-assisted technologies in the writing process by following the instructions below. A statement will appear in the published work. Please note that authors are ultimately responsible and accountable for the contents of the work.

    Disclosure Instructions

    Authors must disclose the use of generative AI and AI-assisted technologies in the writing process by adding a statement at the end of their manuscript in the core manuscript file, before the References list. The statement should be placed in a new section entitled 'Declaration of Generative AI and AI-assisted technologies in the writing process'.

    Statement: During the preparation of this work the author(s) used [NAME TOOL / SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the publication.

    This declaration does not apply to the use of basic tools for checking grammar, spelling, references etc. If there is nothing to disclose, there is no need to add a statement.

    Authorship

    Arthroscopy generally limits the number of authors to 7. If there are more than 7 authors, we ask the corresponding author to justify each author's participation using the ICMJE criteria for authorship:

    1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
    2. Drafting the work or revising it critically for important intellectual content; AND
    3. Final approval of the version to be published; AND
    4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

    Copyright

    Copyright to all published articles will be held by the Arthroscopy Association of North America. Copyright forms are handled by the production department of the publisher once a manuscript is accepted and scheduled for publication.

    Registration of Clinical Trials

    Clinical trial registration (prospective publication of clinical research study authors, title, purpose, hypothesis, methods including statistical methods, and confirmation of Institutional Review Board approval) mitigates against bias resulting from selective reporting of results. Clinical trials beginning patient enrollment after January 1, 2012, will not be accepted for publication in Arthroscopy without prospective registration of the trial (i.e., before enrollment of the first patient). Trials may be registered in any national or international registry. Include details on the separate title page only.

    Except in rare circumstances where the temporal effect of the outcome being measured is brief, clinical trials will not be accepted for publication in Arthroscopy without 24 months' minimum follow-up for all subjects who are enrolled and reported. The Journal strongly encourages the use of the CONSORT (Consolidated Standards of Reporting Trials) guidelines when designing and reporting randomized controlled trials (RCTs). The criteria outlined by the CONSORT group are meant to assist in improving the overall quality of RCTs, and provides a minimum set of recommendations for reporting on RCTs. There is a 25-item checklist designed to facilitate study setup, reporting, and interpretation. The overall goal of using the CONSORT criteria is to facilitate the study design from the outset, and provide for a high-quality and prudently conceived RCT. The guidelines can be found at https://www.equator-network.org/reporting-guidelines/consort/.

    SUBMISSION

    After registering as an author through the Arthroscopy online submission and review system website (www.editorialmanager.com/arth), you will be guided step by step through the uploading of your own files and approving of the single PDF that will be created from them. You can track the progress of your manuscript through our website. Communications about a manuscript will be handled through e-mail. Please access the website for more specifics about online submission, including a tutorial for authors, artwork guidelines, and a link to author support by e-mail that is monitored around the clock.

    Use of inclusive language

    Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Content should make no assumptions about the beliefs or commitments of any reader; contain nothing which might imply that one individual is superior to another on the grounds of age, gender, race, ethnicity, culture, sexual orientation, disability or health condition; and use inclusive language throughout. Authors should ensure that writing is free from bias, stereotypes, slang, reference to dominant culture and/or cultural assumptions. We advise to seek gender neutrality by using plural nouns ("clinicians, patients/clients") as default/wherever possible to avoid using "he, she," or "he/she." We recommend avoiding the use of descriptors that refer to personal attributes such as age, gender, race, ethnicity, culture, sexual orientation, disability or health condition unless they are relevant and valid. When coding terminology is used, we recommend to avoid offensive or exclusionary terms such as "master", "slave", "blacklist" and "whitelist". We suggest using alternatives that are more appropriate and (self-) explanatory such as "primary", "secondary", "blocklist" and "allowlist". These guidelines are meant as a point of reference to help identify appropriate language but are by no means exhaustive or definitive.

    Reporting sex- and gender-based analyses

    Reporting guidance

    For research involving or pertaining to humans, animals or eukaryotic cells, investigators should integrate sex and gender-based analyses (SGBA) into their research design according to funder/sponsor requirements and best practices within a field. Authors should address the sex and/or gender dimensions of their research in their article. In cases where they cannot, they should discuss this as a limitation to their research's generalizability. Importantly, authors should explicitly state what definitions of sex and/or gender they are applying to enhance the precision, rigor and reproducibility of their research and to avoid ambiguity or conflation of terms and the constructs to which they refer (see Definitions section below). Authors can refer to the Sex and Gender Equity in Research (SAGER) guidelinesand the SAGER guidelines checklist. These offer systematic approaches to the use and editorial review of sex and gender information in study design, data analysis, outcome reporting and research interpretation - however, please note there is no single, universally agreed-upon set of guidelines for defining sex and gender.

    Definitions

    Sex generally refers to a set of biological attributes that are associated with physical and physiological features (e.g., chromosomal genotype, hormonal levels, internal and external anatomy). A binary sex categorization (male/female) is usually designated at birth ("sex assigned at birth"), most often based solely on the visible external anatomy of a newborn. Gender generally refers to socially constructed roles, behaviors, and identities of women, men and gender-diverse people that occur in a historical and cultural context and may vary across societies and over time. Gender influences how people view themselves and each other, how they behave and interact and how power is distributed in society. Sex and gender are often incorrectly portrayed as binary (female/male or woman/man) and unchanging whereas these constructs actually exist along a spectrum and include additional sex categorizations and gender identities such as people who are intersex/have differences of sex development (DSD) or identify as non-binary. Moreover, the terms "sex" and "gender" can be ambiguous?thus it is important for authors to define the manner in which they are used. In addition to this definition guidance and the SAGER guidelines, the resources on this pageoffer further insight around sex and gender in research studies.

    PREPARATION

    Peer Review

    This journal operates a double blind review process, which means the identities of the authors are concealed from the reviewers, and vice versa. All contributions are typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final. More information on types of peer review.

    Separate Title Page

    A separate (unblinded) title page of each manuscript should include the following essential information:

    1. Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
    2. All Authors' full names, degrees, and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present each author's affiliation and address below the names.
    3. Corresponding Author. The Journal of Arthroscopy and Related Surgery requires a limit of one corresponding author. Clearly indicate who will handle correspondence at all stages of reviewing and publication, and after publication. Ensure that telephone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.
    4. In addition, include IRB and RCT information, as well as a short running title (maximum of 45 characters and spaces). Include any acknowledgment of persons who provided help during the research/writing (e.g., language help, writing assistance, or proof reading the manuscript, etc.).

    Blinding the Manuscript

    Because all manuscripts are blinded to reviewers, the first page of the blinded manuscript must be a blinded title page that lists only the title. Likewise, in the text, do not include any identifying information, such as an author's initials or the names of institutions where the study was done, or a phrase such as "our study" that, when followed by a citation, reveals authorship of the present manuscript in the reference list.

    Manuscript Structure

    1. Abstract

    Original Articles, abstracts should be a maximum of 300 words and structured to include the following sections: Purpose: One or 2 sentences that simply state the purpose with no background information or hypothesis. Methods: Provide, with sufficient detail, the methods of the study including selection criteria. Results: Provide results, with data, P values, and standard deviation of mean or 95% confidence intervals. Present most important findings first. Please provide exact P values (not P <) and numbers to support your methods findings. Conclusions: State only what your study found; do not include extraneous information not backed up by the results. Level of Evidence (for human studies) or Clinical Relevance (basic science or in vitro study: why is this study important from a clinical standpoint?).

    Systematic Reviews and Meta-analyses, the abstract and text should be structured as an Original Article.

    Technical Notes for Arthroscopy Techniques, the abstract should be an unstructured summary (maximum length, 200 words). The body of these manuscripts should consist of unstructured summary abstract, Introduction, Technique, and Discussion, plus references and figure legends and video legend.

    Case Reports, the text should consist of unstructured summary abstract, Introduction, Case Report, and Discussion, plus references and figure legends.

    Level V Evidence articles, the abstract should be an unstructured summary (maximum length, 300 words). See the Levels of Evidence table.

    2. Introduction

    The introduction of an Original Article should succinctly state the problem or controversy that led you to undertake the study, including a concise review of only the most relevant literature. Conclude the introduction by stating the purpose of the study and your hypothesis. The purpose in the Introduction should match that of the Abstract.

    3. Methods

    Describe the study design (prospective or retrospective, inclusion and exclusion criteria, duration). If prospective or a cadaver study, the number of enrolled subjects is reported in Methods. If retrospective, the study population (numbers, demographics, length of follow-up) should be in Results.

    Include IRB and animal studies information. IRB approval is required for all human studies except retrospective and cadaver studies (unless the institution where the study was performed requires it).

    The statistics that you have used to analyze the data should be described in detail. You cannot make the statement, "We found no significant difference between the two groups" unless a power study was done and you include in the text the value of alpha, beta, and standard deviation. Use of the word significant requires your reporting an exact P value. Confidence intervals of 95% are required whenever the results of survivorship analysis are given in the text, tables, or figures. Use of the word correlation requires you to report the correlation coefficient.

    Arthroscopy encourages the use of validated outcome instruments. The use of both a general health outcome measure and a joint-specific, limb-specific, or condition-specific measure is encouraged. If an outcome instrument leads to a categorical ranking (e.g., excellent or good or poor), the aggregate outcome score for each patient should be provided.

    4. Results

    Describe in detail the data obtained during the study following the order of the Methods to include final number of subjects, demographics, length of follow-up (mean and range). The overall final patient follow-up should be 80% or greater (less than 20% drop-out) in order to minimize follow-up bias. In general, scientific studies will not be accepted for publication without meeting this criterion. Results obtained with less than two years of follow-up are rarely accepted for publication by the Journal. All data in the text must be consistent with the rest of the manuscript, including data in tables, figures, and legends. Present comparison data in tables and present as mean ± standard error of the mean with confidence intervals.

    5. Discussion

    Be concise. The Discussion should start with the most important findings of your study. Is your hypothesis affirmed or refuted? Compare and contrast your study with others in the most relevant world literature, particularly the recent literature. A complete literature review is unnecessary.

    At the end of the Discussion, under the subheading "Limitations," review the limitations of your study.

    6. Conclusions

    Briefly state your new (or verified) view of the problem you outlined in the Introduction. Take special care to draw your conclusions only from your results and verify that your conclusions are firmly supported by your data. Most importantly, do not make concluding statements that are not supported by your data, lie beyond the scope of your study, or are unnecessary (e.g., "further studies are warranted"). The conclusions in the text must match those in the abstract.

    7. References

    The Journal follows AMA reference style. See examples below. Provide all authors' names when 6 or fewer; when 7 or more, list the first 3 and add et al. Provide article titles and inclusive page numbers (321-328, not 321-8). References to online-only material must list author, title, the URL, and the date accessed by the author. For abbreviations of journal names, refer to PubMed. Please ensure that every reference cited in the text is present in the reference list (and vice versa). The accuracy of reference data is the responsibility of all authors.

    Data References
    This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. This identifier will not appear in your published article.

    Reference style
    In text: Number references in the order in which they appear in the text. Unpublished results and personal communications (only if essential to your message) should be mentioned in the body of the text at the end the statement with the appropriate information in parentheses. For example: (J. Karlsson, M.D., personal communication, [month and year of communication]).

    SYSTEMATIC REVIEWS (WITH AND WITHOUT META-ANALYSIS)

    Refer to Harris JD, Brand JC, Cote MP, Dhawan A; Research Pearls: The Significance of Statistics of Perils of Pooling: Pearls and Pitfalls of Meta-analyses and Systematic reviews; Arthroscopy 2017; E-published April 27, 2017 for guidance in design, conduct, reporting, and publishing SR/MA in Arthroscopy.

    General

    Review authors are encouraged, but not required, to register the systematic review (SR) on PROSPERO (https://www.crd.york.ac.uk/PROSPERO/) after the review topic is conceived, but before the conduct of the review begins. Submission of a SR should follow the 27-item PRISMA checklist (http://www.prisma-statement.org/). The following guidelines incorporate key elements of the PRISMA checklist and are intended to improve the quality of SR submissions:

    Introduction

    • Rationale for why a SR is needed should be clearly described. What is already known about the topic, current gaps in knowledge, and why a SR is likely to produce evidence that will serve to address these gaps should be clearly stated. If a similar or identical SR/MA has been published in last 5 to 10 years, then the submitted SR/MA must show that the evidence has changed.
    • Define the specific research question, preferably in PICO format (Participants, Interventions, Comparisons, and Outcomes).
      o Example: In collision athletes, does open Bankart repair, in comparison to arthroscopic Bankart repair, result in lower rates of recurrent instability?

    Methods

    Study Eligibility (Inclusion and Exclusion Criteria)

    • Eligibility criteria should follow the PICO question defined in the Introduction.
      o Example:Studies that included collision athletes with a Bankart lesion undergoing primary repair, compared open to arthroscopic treatment, and reported recurrent instability rates at two years or greater follow up were eligible for inclusion.
    • Other pertinent criteria for determining eligibility including type of studies (Level of Evidence, study design, etc.) that was reviewed.
      o Example:Case series (Level IV evidence) or studies that did not specifically compare open to arthroscopic treatment were excluded.
      o Consult CEBM (http://www.cebm.net/ocebm-levels-of-evidence/) for thorough descriptions of level of evidence in therapeutic, diagnostic, prognostic, and economic studies.

    Literature Search

    • The search strategy (terms, string) should be described with enough detail that it could be reproduced.
    • Indicate which databases were searched. Two or more databases should be used (the combination of MEDLINE, EMBASE, and Cochrane will capture 97% of all relevant studies in Orthopedic Surgery SR/MA).
    • The search should be performed independently by two or more study authors to ensure no omission of potentially relevant subjects and resolution of disagreement in the setting of possible study inclusion.

    Study Selection and Data Abstraction

    • The process for selecting studies, indicating who screened the studies and how were disagreements managed should be clearly described.
    • The specific data that were extracted from each study and information on who abstracted the data, what tools (data collections forms, etc.) were used to facilitate abstraction, and how were disagreements managed should be described.

    Risk of Bias Assessment

    • The process used to appraise the methodological quality or risk of bias including the tools use for appraisal should be clearly described.
    • The tools used to evaluate the studies should be appropriate for the design of the included studies. Common tools include Cochrane’s Risk of Bias for randomized clinical trials, Coleman, Modified Coleman, CONSORT, Newcastle-Ottawa or MINORS for observational non-randomized studies.
    • Multiple, independent raters for the risk of bias assessment are recommended. Rater statistics (kappa, ICC) should be reported to quantify the degree agreement between the raters and a description of how disagreements were handled, i.e. how the final score was arrived at, should be included.

    Data Analysis

    • The primary outcome measure(s) should be clearly stated.
      o Example: The primary outcome measure was the rate of recurrent instability. Risk ratios (rate in open group divided by the rate in arthroscopic) were calculated for each study.
    • If a meta-analysis is performed, the rationale or criteria used for determining that pooling data was appropriate should be provided.
    • In nearly all situations, meta-analysis should only be performed with level I or II evidence studies.
    • The methods used to analyze the data (fixed versus random effects) and measures of heterogeneity or consistency (I2) should be clearly described.
    • For a meta-analysis using a random effect model, prediction intervals are strongly recommended.
    • Plans for exploring heterogeneity or inconsistency between studies, including subgroup analyses and meta-regressions should be clearly described.
    • Any additional analyses (sensitivity, publication bias) should also be clearly described.

    Results

    • Presentation of the results should follow the Methods section.
    • The study selection process should be depicted in a PRISMA flow chart.
    • Risk of Bias scores should be presented for each item on the selected tools. Reporting aggregate scores is OK however scores for each item are needed to determine the specific areas where studies were at risk for bias.
    • For SR without a meta-analysis, forest plots with the summary estimate suppressed are recommend as they allow the effects of the individual studies and their relative size and weight to be displayed together in the same figure.

    Discussion and Conclusion should follow the Journal’s guidelines for original research.

    Common Errors

    • Including studies with duplicate patient populations. In some instances a SR turns up studies on the same patient group. Including these studies in any statistical analysis artificially inflates the number of patients and should be avoided.
    • Pooling diverse, heterogeneous studies with different designs.Combining non-randomized studies with randomized trials is typically not appropriate as these designs carry different risks of bias and are apt to distort the results. If a SR includes studies with different designs (randomize trials, cohort studies, etc.) these should be pooled separately. Typically, these are level III or IV evidence studies.
    • No rationale for provided for pooling non-randomized studies. If the available literature is limited to observational studies, a rationale for why a meta-analysis will produce valid results that contribute to the understanding of the problem under question is needed. If one can not be reached, a meta-analysis should be avoided.
    • Quantifying heterogeneity but not failing to explore or discuss it. Reporting of the I2 statistic has become more frequent however it’s important to discuss its impact on the results. If the results are heterogeneous efforts should be undertaken to explore this inconsistency. Techniques like subgroup analysis can be used to determine if I2 values change when grouped according to co-variants. For example, I2 values may change when the studies are analyzed according to a clinical characteristic (those that included patients with bone loss vs. those that did not) or a risk of bias item (those that adequately randomized patients versus those that did not). Lastly, I2 is a relative measure. As recommended above, providing a prediction interval will assist in interpreting the effect of heterogeneity. A prediction interval provides a range of probable effects that reflects the variation in the different studies and settings, including what would be expected in future patients.
