Arthroplasty Today

1. OVERVIEW

Arthroplasty Today is an official journal of the American Association of Hip and Knee Surgeons. The journal brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today attracts manuscripts of the highest quality from all areas of scientific endeavour that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. Please review these Author Instructions and Editorial Policies before submitting your manuscript to Arthroplasty Today (https://www.editorialmanager.com/artd).

It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal's area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.

Arthroplasty Today is also a forum for information relating to the advocacy mission of the American Association of Hip and Knee Surgeons.

2. OPEN ACCESS

Arthroplasty Today is an open access journal. There is usually a fee associated with publication if your manuscript is accepted. Look here for details. Please note that if there is financial hardship, authors may request scholarship funding in their cover letter (funding is not guaranteed).

Authors may be recruited to write thematic articles or invited to contribute to a special topical issue, and the open access APC fee will be waived at the discretion of the Editor in Chief. To encourage loyalty in the arthroplasty author community, the Editor in Chief will waive the APC fee to an author who is publishing their third paper in the same year in Arthroplasty Today. The same author must have published two papers in Arthroplasty Today in the same year, for the third paper to be free. Please note this on the title page of the third paper submission. In all instances above, there is no guarantee of paper acceptance and the regular double-anonymized peer review process will occur.

If the APC is waived, the corresponding author will require a waiver code, which is a long unique string of numbers and letters, that the corresponding author will insert into the rights and access form once their paper is accepted. To watch a video on completing the rights and access form with an APC waiver code: https://supportcontent.elsevier.com/Support%20Hub/Journals/29789_Voucher_code.mp4

To inquire about waivers, please contact Dr. Golladay, the Editor in Chief at [email protected].

3. EDITORIAL POLICIES

Arthroplasty Today follows the International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals. The journal is also a member of the Committee on Publication Ethics (COPE) and the Editor-in-Chief will follow the COPE guidelines to investigate allegations of scientific misconduct and unethical acts including, but not limited to, plagiarism, data fabrication or falsification, and duplicate publication relating to published articles or manuscripts under consideration by the journal. Submissions are subject to screening through iThenticate to validate the originality of the content submitted.

3.1 Peer Review Process

All submitted manuscripts are initially assessed by the Managing Editor for completion. Each article is then assigned to the Editor-in-Chief or Deputy Editor. Manuscripts that are not within the scope of Arthroplasty Today or are otherwise deemed inappropriate for the journal may be rejected at this stage. Papers deemed suitable will be assigned to an Associate Editor who will oversee the peer review process. For all manuscripts, Arthroplasty Today follows a double-blind peer review process, and requires two external reviews to be completed before a decision is reached. The Editor-in-Chief makes the final accept and reject decisions. Editors and Editorial Board members are not involved in the review, acceptance or rejection decisions on manuscripts they have authored, those authored by family members or arm's length colleagues, or articles relating to products or services in which they have an interest.
The Editor, Deputy Editor, and Associate Editors of Arthroplasty Today will not be involved in editorial decisions about their own scholarly work. Prior to peer review, the Managing Editor will identify if the Editor, Deputy Editor, or Associate Editor is an author or has contributed to a manuscript. The Managing Editor will ensure that the Editor, Deputy Editor, or Associate Editor has no involvement in the editorial review of the manuscript, no access to confidential information on the editorial process, and no input on editorial decisions. Authorship by the Editor, Deputy Editor, or Associate Editor will be acknowledged in the Conflict of Interest Statement of the published article noting they have been recused from reviewing or making editorial decisions for the manuscript. Additionally, Editorial Board members must recuse themselves from handling manuscripts in cases where they have a conflict of interest, financial or otherwise.

3.2 Special Issues and Collections

The peer review process for Special Issues and Article Collections observes the same standards as for regular submissions. Papers submitted to a Special Issue are assigned to its external Guest Editor. The Guest Editor sends the manuscript to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Guest Editor makes a recommendation for the decision to the Editor in Chief. The Editor in Chief is responsible for the final decision regarding acceptance or rejection of articles. The Editor in Chief oversees the peer review process of all Special Issues and Articles Collections to ensure the journal's normal high standards of publishing ethics and responsiveness are respected. Guest Editors are not involved in decisions about papers which they have written themselves or have been written by family members or colleagues or which relate to products or services in which the guest editor has an interest. Any such submission is subject to all of the journal's usual procedures, with peer review handled independently of the relevant editor and their research groups.

Arthroplasty Today occasionally publishes joint article collections in collaboration with other Elsevier journals, presenting papers that have been published in Arthroplasty Today and one other title. This can be the case when several journals are covering one conference, or/and are publishing novel articles around one same topic.

3.3 Authorship

Arthroplasty Today adheres to the authorship requirements as defined by ICMJE. Each person listed as an author is expected to have participated in the study to a significant extent in accordance with the ICMJE Recommendations on Defining the Roles of Authors and Contributors. To qualify for authorship in accordance with ICMJE, a contributor must have fulfilled each of the following criteria: 1) substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data; 2) drafting the article 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 and integrity of any part of the work are appropriately investigated and resolved. All persons designated as authors should qualify for authorship, and all those who qualify should be listed. Each author should have participated sufficiently in the work to take public responsibility for its content. Any changes to authorship after initial submission must be agreed by all co-authors. Changes to the authorship list after acceptance will only be considered under extraordinary circumstances and requested through the Editorial Office. Changes to the author list or order of authors made at page proofs will not be implemented.

For transparency, we require corresponding authors to provide co-author contributions to the manuscript using the relevant CRediT roles. The CRediT taxonomy (here) includes 14 different roles describing each contributor's specific contribution to the scholarly output. The roles are: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualization; Roles/Writing - original draft; and Writing - review and editing. Note that not all roles may apply to every manuscript, and authors may have contributed through multiple roles. More details and an example.

3.4 Declaration of Generative AI in scientific writing

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, not to replace key researcher tasks such as interpreting data or drawing scientific conclusions.


• Apply the technology with human oversight and control, and carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete or biased.


• Not list AI and AI-assisted technologies as an author or co-author, or cite AI 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.


• 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 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.

3.5 Ethics in publishing

For information on Ethics in publishing and Ethical guidelines for journal publication see https://www.elsevier.com/publishingethics and https://www.elsevier.com/journal-authors/ethics.

3.6 IRB Policy and Animal Studies

Manuscripts describing research involving human or animal subjects must include the institutional affiliation of the Institutional Review Board (IRB) or Animal Use Committee that provide consent for the research described in the manuscript, included the protocol or application number. When reporting experiments on human subjects, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration (JAMA 2000;284:3043-3049). When reporting experiments on animals, indicate whether the institution's or a national research council's guide for, or any national law on, the care and use of laboratory animals was followed (for example National Research Council's Guide for the Care and Use of Laboratory Animals). This information must be included in the last sentence in the Methods section of the submission and if accepted will be published in the article.

3.7 Informed consent and patient details

Studies on patients or volunteers require ethics committee approval and informed consent, which should be documented in the paper. Authors must ensure that submissions to the journal are HIPAA-compliant (http://www.hhs.gov/ocr/hipaa/). This information should be noted in the Methods section of the article. Appropriate consents, permissions and releases must be obtained where an author wishes to include case details or other personal information or images of patients and any other individuals in Arthroplasty Today. Written consents must be retained by the author but copies should not be provided to the journal. Only if specifically requested by the journal in exceptional circumstances (for example if a legal issue arises) the author must provide copies of the consents or evidence that such consents have been obtained. For more information, please review the Elsevier Policy on the Use of Images or Personal Information of Patients or other Individuals. Unless you have written permission from the patient (or, where applicable, the next of kin), the personal details of any patient included in any part of the article and in any supplementary materials (including all illustrations and videos) must be removed before submission.

3.8 Funding Sources

It is the author's responsibility to identify and declare all funding sources received for the research submitted to the journal. All funded articles will be published with a statement of Funding Sources acknowledging the funders. The Funding Sources statement will be published at the end of the article between Acknowledgements and the Conflict of Interest Statement.

3.9 Clinical trial policy

Registration in a public trials registry is a condition for publication of clinical trial research in this journal. Trials must be registered at or before the onset of patient enrollment. Authors should supply the clinical trial registration number to the editors in the submission process, on the title page and on the CONSORT checklist that accompanies the randomized controlled trial manuscript. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects of health outcomes. Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example drugs, surgical procedures, devices, and process-of-care changes). Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

3.10 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) guidelines and 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 page offer further insight around sex and gender in research studies.

3.11 Conflict of Interest Statement

It is the responsibility of authors to disclose all actual or potential conflict of interest including any financial, consulting, personal or other relationships with other people or organizations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. Two Conflict of Interest Statements are required: one individual disclosure submitted by each author, signed (signature or typed), and dated; and one combined, blinded form submitted without author names but with all authors' disclosure information on one form. All articles will publish with a Conflict of Interest Statement noting the conflicts declared by each author and/or if no conflicts were declared. The Conflict of Interest Statement will be published at the end of the article between Funding Sources and References.

The individual Conflict of Interest form can be found here

The combined (blinded) Conflict of Interest form can be found here.

Authors who serve as Journal Editors should note this on the title page of their submission, as they will have to be recused from peer review and any editorial decisions.

3.12 Preprint Policy

Arthroplasty Today will consider for publication manuscripts that have previously been posted on a nonprofit preprint server (i.e., bioRxiv, medRxiv, etc.) Availability on a preprint server, including a link to the preprint, must be disclosed at submission. Posting or updating the preprint while under review by the journal is not permitted.

3.13 Rejection Appeals

Authors may appeal an Editor's decision if they think it is unwarranted. Appeals must be submitted by email to the Editorial Office ([email protected]), with details substantiating the request for reconsidered. Please do not resubmit rejected articles. The Editor-in-Chief will review all appeal requests and may reject the appeal or agree to further review of the manuscript. Appeal decisions are final.

3.14 Copyright and Licence to Publish

The authors retain copyright to articles published in Arthroplasty Today. Once accepted, authors will receive correspondence from Elsevier guiding them to select the appropriate Creative Commons License to Publish granting AAHKS and the publisher a license to publish the article and will provide instructions to pay the Article Processing Charge.

3.15 Post-publication Corrections

Authors should notify the Editorial Office as soon as possible if errors or omissions are found in their published article, particularly errors that could affect the interpretation of data or reliability of the information presented. Changes to a published article (version of record) should be submitted to ONO in the form of a correction notice providing the details of the error and the requested changes. Requests for post-publication corrections will be considered by the Editor-in-Chief and will be made in accordance with guidance from the Committee on Publication Ethics (COPE). It is the responsibility of the corresponding author to ensure consensus has been reached with all co-authors before requesting a correction. Depending on the nature of the correction, a Corrigendum or Erratum notice (and in rare cases an Expression of Concern or Retraction notice) will accompany all post-publication corrections. To ensure the integrity of the scholarly record, the correction notice will be permanently linked with the original article. For certain types of corrections, the original article will be corrected but will still be accompanied by the appropriate correction notice. The journal supports trans and non-binary authors who wish to update their name following article publication. Such a change will NOT be accompanied by a correction notice. For more information, please contact the Editorial Office for more information.

4. ARTICLE TYPES

Arthroplasty Today requires adherence to appropriate reporting guidelines and checklists dependent on the type of study being conducted. For example:

Randomized controlled trials	CONSORT
Observational studies	STROBE
Systematic reviews	PRISMA
Case reports	CARE
Clinical practice guidelines	AGREE

For more a complete list of reporting guidelines and checklists, please visit the Equator Network.

Case Reports. Case Reports are defined as a narrative that describes for medical, scientific or educational purposes a medical problem experienced by a small number of patients (typically one to five). The report usually describes a diagnostic dilemma, unusual manifestation of the disease process, unusual treatment challenge, unanticipated early failure, or complication.

A case report follows CARE guidelines (Gagnier, J., et al. The CARE guidelines: consensus-based clinical case reporting guidelines development. Journal of Medical Case Reports 2013, 7:223) and is typically fewer than 2,000 words. Each case report will have the following components: Title, Keywords, Abstract, Introduction, Case History, Discussion and Summary. The Case history must include: informed consent, patient information, clinical findings, timeline, diagnostic assessment, therapeutic intervention, follow-up and outcomes. In addition, the patient should share his or her perspective or experience wherever possible.

The author(s) must confirm during the submission process that informed consent has been obtained from the involved patient(s) or if appropriate from the parent, guardian, power of attorney of the involved patient(s); and, they have given approval for this information to be published in their submission. Authors can download and complete a Patient Informed Consent template. The completed forms do not need to be submitted with the submission, only held by the corresponding author.

Arthroplasty in Patients with Rare Conditions. This type of format is used to highlight joint replacement in patients with a rare underlying condition (usually 1 percent or less of joint replacement patients). This type of case report is a narrative that describes the unusual treatment challenge of performing an arthroplasty because of the underlying condition. An example would be the report of a total hip replacement in a patient with spastic paralysis of the lower extremity.

This case report follows CARE guidelines (Gagnier, J., et al. The CARE guidelines: consensus-based clinical case reporting guidelines development. Journal of Medical Case Reports 2013, 7:223) and is longer than a case report (3,000 words) because of an expanded discussion section. Each case report will have the following components: Title, Keywords, Abstract, Introduction, Case History, Discussion and Summary. The Case History must include: informed consent, patient information, clinical findings, timeline, diagnostic assessment, therapeutic intervention, follow-up and outcomes. In addition the patient should share his or her perspective or experience wherever possible. The discussion section in this format should also include a summary of historical and contemporary treatment, as well as a list of three to five key points, and a discussion subsection title "Current Controversies and Future Considerations."

Original Research Articles (Clinical and Basic Science). Arthroplasty Today accepts basic science and clinical research papers. Papers must be original, not published elsewhere, and must not be under consideration for publication elsewhere. Original research articles are typically fewer than 4,000 words.

Each research manuscript will have the following components: Title, Keywords, Abstract, Introduction (state the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results), Material and methods (provide sufficient detail to allow the work to be reproduced; methods already published should be indicated by a reference), Results (results should be clear and concise), Discussion (this should explore the significance of the results of the work, not repeat them), Conclusions (the main conclusions of the study may be presented in a short Conclusions section, which should stand alone). The manuscript must include informed consent.

Systematic Review. A systematic literature review is defined as an exhaustive review and summary of published research studies with the aim of answering a specific research question or questions. Systematic literature reviews may be qualitative (e.g. aggregating, analyzing, and reporting the results of multiple studies) and/or quantitative (e.g. employing statistical methods, such as meta-analyses to increase the effect of individual findings from multiple studies). Please note that meta-analysis should only be utilized in cases where the pooled data is from comparable study designs, examining similar procedures, and the I2 value of the meta-analysis is less than 50%.

Reviews must be original, not published elsewhere, and must not be under consideration for publication elsewhere. Reviews are typically under 4,000 words.

Systematic literature reviews will report the following components, based on the PRISMA Guidelines For Transparent Reporting of Systematic Reviews and Meta-Analyses: Title, Keywords, Abstract, Introduction and background, Material and methods (provide sufficient detail to allow the work to be reproduced; for example: journals searched, search strategy, inclusion/exclusion criteria, quality appraisal of included studies, data analysis/statistical techniques used, etc.), Results (if a meta-analysis was conducted, please provide the results of the meta-analysis, along with the included studies, forest plot, and I2 values; note that meta-analyses with an I2 value over 50%, will not be accepted due to concerns regarding high heterogeneity across the pooled study data; include all relevant statistics for statements regarding comparative effectiveness, such as p-values, percentages, N, mean, confidence intervals, etc.), Discussion, Conclusions (the main conclusions of the study may be presented in a short Conclusions section, which should stand alone, Figures (including a study attrition chart, Additional Supporting Materials (e.g. appendices, study attrition flowchart, etc.).

Brief Communications. Brief Communications are meant to be reports that promptly disseminate new ideas and observations. These ideas may not be sufficiently mature or evaluated to merit publication as a full manuscript and yet may be of interest and importance. An example would be the report of a group of catastrophic failures of a new implant design that would serve as an early warning to the readership. Brief Communications will be limited to two printed pages, including text, tables, figures, and references. This corresponds to six double-spaced standard manuscript pages, with one page of text eliminated for every figure or table added. References should be limited to less than 10. In addition, the standard format for papers—Introduction, Material and methods, Results, Discussions, and Conclusions—may be eliminated; however, please include a brief abstract. Brief Communications will be reviewed as soon as possible and, when accepted, published in the next possible issue.

Viewpoint (opinion). A Viewpoint submission is a narrative that presents the opinion of a member or members of the arthroplasty community where intriguing, stimulating, controversial or insightful ideas are presented. These discussions on health-care policy, economics, ethics, decision making, volunteerism, or the occupational challenges of surgical staff, for example, may not necessarily be endorsed by Arthroplasty Today or the American Association of Hip and Knee Surgeons. The authors should build a concise argument that tries to influence readership opinion, encourage critical thinking, and inspire readers to take action. This format has an introduction, body, and conclusion; objectively explains a timely issue; often references conflicting viewpoints; and takes a pro-active approach to better the problem presented (by giving constructive criticism). Each manuscript will be peer-reviewed and edited before publication. Viewpoint manuscripts should be 1000 words or fewer.

Editorial and Guest Editorial. An editorial is a narrative that presents the journal's opinion on an issue. It usually reflects the editor-in-chief's opinion or the majority of the editorial board. Editorial writers attempt to build an argument that tries to influence readership opinion, promote critical thinking, and encourage readers to take action. An editorial has an introduction, body, and conclusion; objectively explains a timely issue; often references conflicting viewpoints; and takes a pro-active approach to better the problem presented (by giving constructive criticism). Editorials should be 500 words or fewer.

Guideline/ White Paper. A white paper is a short document (2,000-3,000 words) to state an organization's policy, position, or philosophy about a subject or to pose a problem or question and then answer that question with information or a proposed solution. A white paper can serve to increase understanding of a particular issue, provide information to aid in decision making, or present a professional perspective. Often, a white paper explains the results or conclusions resulting from some organized committee, research collaboration, or design and development effort.

Each white paper will have the following components: Title, Keywords, Abstract, Introduction, Problem statement, Proposed solutions, Future direction and long term focus and Recommendations.

Surgical Technique/ Office Tip. Technique and Tip reports are defined as a narrative that presents a unique technique or tip that is helpful in the operating room or office. This feature usually describes a novel concept that helps with efficiency or improvement in the care of the arthroplasty patient. A Surgical Technique/Office Tip report is typically fewer than 2,000 words and includes the following components: Title, Keywords, Abstract, Introduction, Surgical Technique or Office Tip, Discussion and Summary. Authors are not required to submit review questions related to technique or tip.

Letter to the Editor. Letters to the editor are usually fewer than 500 words and offer a viewpoint or experience about a manuscript previously published in Arthroplasty Today. The letter should be appropriately referenced, and clearly state questions or comments from the author(s). Authors are required to sign and send a conflict of interest statement at the time of submission.

Other. On occasion other types of manuscripts may be acceptable for submission, peer review, and publication by Arthroplasty Today. Please contact the Editorial Office with questions about potential submissions.

4.1 Information for all Manuscripts

Line spacing, line numbering, and page numbers. All submissions should have 1.5 or double spacing and continuous line numbering. Page numbers should also be present in the lower right corner of each manuscript page.

Title page. Authors are required to complete a title page with their submission. Please download the journals' title page template and submit it as part of your paper.

Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. List affiliation (department spelt in full), school, hospital, or organization), city, state/province, country. Use two-letter postal codes for US state abbreviations. Use "USA" for United States and "UK" for United Kingdom. Do not include the postal mailing address for the corresponding author (or any author) here with the affiliations. (The actual mailing address appears only in the footnotes at the bottom of the page.)

Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.Corresponding author affiliation appears in a footnote in the title page of the submission, this should contain the street and full postal address, without the institution or department.The format for the phone number is: +X XXX XXX XXXX (country extension, followed by area code and phone number-include spaces but no hyphen). Only use 1 email address which should be all lowercase, no period at end. Contact details must be kept up to date by the corresponding author.

Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

Abstract. A structured abstract (max 250 words) is required for Original Research and Systematic Reviews. The headings for the structured abstract are always:

• Background
• Methods
• Results
• Conclusions

An unstructured abstract (max 125 words) is required for Case Report, Arthroplasty in Patients with Rare Conditions, White Paper/Guideline, Surgical Technique, and Office Tip articles.

An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Please note: No abstract is used in Editorial, Guest editorials, Note from the editor, Viewpoint, Obituary, Book review, Letter to the editor, and Response to letter to the editor.

Keywords. Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Abbreviations. Define by writing out the entire phrase when it is first used in the manuscript, followed by the abbreviation in parentheses. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there. Ensure consistency of abbreviations throughout the article.

4.3 Figures

Figure citations within the text should be abbreviated when within parentheses and spelled out in full when part of the sentence. Examples: inserted parenthetically (Fig. 2).; Figure 3 shows; with parts (Fig. 4a and b).; more than one (Figs. 5 and 6),

The figure legend should be clear without the reader having to consult the main text. Abbreviations may be used without expansion if already introduced in the text. Example: Radiograph of AP pelvis demonstrating a healed fracture at 1 year.

Always refer to parts of a figure in lowercase letters (eg, a, b):

Figure 1. Initial iliac oblique radiograph (a) upon patient arrival demonstrating the comminuted periprosthetic acetabular fracture. The large attached posterior column fragment (open arrow) with associated screws remains well fixed to the displaced cup. Fracture through the anterior column (closed arrow) is also seen. A selected cut from the preoperative computed tomography scan (b) demonstrates the portion of the posterior column that remained well fixed to the displaced acetabular component.

X-ray figures. If there is an anteroposterior and lateral X-ray from the same time frame-ie pre-operative or 2 year postoperative-they should be in the same Figure. For example, Figure 1a would be pre-operative anteroposterior radiograph and Figure 1b would be pre-operative lateral radiograph.

Figure captions. Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Tables. Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

Acknowledgements. Collate acknowledgements and any funding in the separate section at the end of the title page. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.), as well as any funding sources, please note do not include anything in this section if there are no acknowledgments or funding sources for your paper.

Appendices. If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

When referencing a website, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, references to a source application, etc.), should also be given.

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 formatting

This journal uses Vancouver reference style, the same style as the Journal of Arthroplasty. Please use this formatting at submission. A website that is useful is https://www.mybib.com/tools/vancouver-citation-generator. Include the DOI in each reference. Note that missing data or formatting inquiries will be highlighted at proof stage for the author to correct. Here are some examples:

4.5 Artwork

Electronic artwork

General points
• Number the illustrations according to their sequence in the text.
• Provide captions to illustrations separately.
• Submit each illustration as a separate file.

A detailed guide on electronic artwork is available on our website: https://www.elsevier.com/artworkinstructions.

You are urged to visit this site; some excerpts from the detailed information are given here.

Formats

If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply “as is” in the native document format. Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, please “Save as” or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):

EPS (orPDF): Vector drawings, embed all used fonts.

TIFF (orJPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.

TIFF (orJPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi.

TIFF (orJPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.

Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

4.6 Color artwork

Please make sure that artwork files are in an acceptable format (TIFF (or JPEG), EPS (or PDF), or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork, please see https://www.elsevier.com/artworkinstructions.

Please note: Because of technical complications that can arise by converting color figures to “gray scale” (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.

4.7 Illustration services

Elsevier's WebShop ( http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs.
