A manuscript submitted to this journal can only be published if it (or a similar version) has not been published and will not be simultaneously submitted or published elsewhere. A violation of this condition is considered fraud, and will be addressed by appropriate sanctions. Two manuscripts are considered similar if they concern the same hypothesis, question or goal, using the same methods and/or essentially similar data.
Arthroplasty cohort studiesThe 2-year minimum follow-up of at least 100 cases applies to arthroplasty cohort studies, unless reporting a failing implant.
Preparation of the ManuscriptSummary of Overall Arrangement of Manuscripts

Randomised controlled trialsCohort, case-control and cross-sectional studies
All randomised controlled trials submitted for publication in The Knee should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement website at http://www.consort-statement.org for more information. The Journal has adopted the proposal from the International Committee of Medical Journal Editors (ICMJE) which require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Trials must register at or before the onset of patient enrolment. The clinical trial registration number should be included at the end of the abstract of the article. For this purpose, a clinical trial is defined as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g. phase I trials) would be exempt. Further information can be found at www.icmje.org.
Submissions reporting cohort, case-control and cross-sectional studies should conform to the format suggested by the STROBE panel (http://www.strobe-statement.org).Meta-analyses
Reporting of meta-analyses should conform to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Statement criteria. These are available at http://www.prisma-statement.org/.Levels of Evidence for Primary Research Question
Level 1: Therapeutic studies will employ a high-quality randomised controlled trial with statistically significant difference or no statistically significant difference but narrow confidence intervals. Prognostic studies investigating a patient characteristic on outcome of a disease require a high-quality prospective study (all patients were enrolled at the same point in their disease with 80% follow-up of the enrolled). A previously developed diagnostic criteria is evaluated with a consecutive series of patients against a universally applied "gold standard" . A systematic review should include two or more Level I studies that revealed consistent results that may be compared.Level II: Therapeutic studies include lesser quality randomised control studies where follow-up is less than 80%, no blinding was utilised, or randomisation was flawed. Included are prospective comparative studies where patients at a single institution are compared with different treatment methods. For prognostic studies that evaluate a patient characteristic on the outcome of a disease, included are retrospective studies and certain prospective studies (lesser than 80% followup and patients enrolled at different stages of the disease). Studies investigating diagnostic criteria consider consecutive patients compared against a gold standard where the criteria are evaluated during the study. Systemic reviews are made of level II studies and level I studies with inconsistent results.
Level III:This group includes case-control studies where patients sustaining one outcome, "case" are compared against another group without that outcome, the "control". For diagnostic criteria, cohorts are non-consecutive and the "gold standard" was not consistently applied. Systemic review are made of level III studies.Level IV: This group includes case series where patients are treated in one way and there is no comparison group. For diagnostic criteria, this includes case-control studies, and studies with a poor reference standard.
Level V: Only expert opinion is considered in this group.Preparation of Supplementary Data

Changes to AuthorshipReview and Publication Process
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.
1. You will receive an acknowledgement of receipt of the manuscript by the Editorial Office before the manuscript is sent to referees. Please contact the appropriate Editor if you do not receive an acknowledgement.
Following assessment one of the following will happen:A: The paper will be accepted directly. The corresponding author will be notified of acceptance by email. The accepted manuscript will be sent by the Editor to Elsevier Ltd., for publication.B: The paper will be accepted subject to minor amendments. The corrections should be made and sent back to the Editor for checking. Once the paper is accepted the procedure as in 'A' above will be followed.
C: If the reviewers recommend major revisions to the paper, it will need to be re-reviewed before a final decision is made. The revisions should be made and the paper sent back to the Editor. The paper will be re-evaluated by referees and the assessment process will start again.D: The paper will be rejected outright as being unsuitable for publication in The Knee.
2. By submitting a manuscript, the authors agree that the copyright for their article is transferred to the publisher if and when the article is accepted for publication. http://www.elsevier.com/wps/find/authorshome.authors/copyrightCopyright
3. One set of page proofs in PDF format will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post).
