Late-Breaking Abstract Eligibility Requirements

What is the Late-Breaking Abstract Program?

The Late-Breaking Abstract program is designed to highlight new, innovative, and time-sensitive orthopaedic research that was not ready for submission during the regular abstract cycle. This opportunity is reserved for studies with significant findings, data, or results that became available after the regular Annual Meeting abstract submission period.

The Late-Breaking Abstract deadline is October 30.

Previously Submitted Abstracts Are Not Eligible

Abstracts submitted during the regular Annual Meeting abstract submission cycle are not eligible for the Late-Breaking Abstract program. This includes abstracts that were:

Rejected
Withdrawn
Revised after submission
Updated with new data following the original submission

The Late-Breaking Abstract process is intended for new research findings that were unavailable during the regular submission period. Missing the original deadline does not qualify a submission as late-breaking.

Eligibility Requirements

To be considered for the Late-Breaking Abstract program, submissions must meet all of the following criteria:

Newly Available Data

The abstract must include significant findings, results, or data that became available after the regular abstract submission deadline.

Authors should be prepared to identify when the key data became available.

True Late-Breaking Research

The research must not have been reasonably submitted during the regular abstract cycle because critical study data, analyses, or results were not yet available.

Failure to submit before the regular deadline does not qualify a study as late-breaking.

Original Research

Submissions must present original orthopaedic research and include:

Clear objectives
Defined methods
Study results
Evidence-based conclusions

Abstracts should contain sufficient data to support the conclusions presented.

Orthopaedic Relevance

Research must demonstrate relevance to one or more of the following areas:

Orthopaedic surgery
Musculoskeletal care
Clinical practice
Medical education
Research
Emerging technologies

Scientific or Clinical Impact

Findings should have the potential to advance orthopaedic knowledge or improve patient care through:

New scientific insights
Changes in clinical understanding
Emerging technologies
Improved outcomes
Advancements in the field of orthopaedics

Completed or Substantially Completed Results

Abstracts must include actual study results.

The following are generally not eligible:

Planned studies
Study protocols
Concept proposals
Research without sufficient supporting data

Disclosure Requirements

There is no disclosure grace period for Late-Breaking Abstract submissions. All authors must have a current disclosure on file, dated April 1, 2025, or later, by the close of the Late-Breaking Abstract application cycle on October 30, 2026.

Applications with one or more authors who do not have a current disclosure on file by the deadline will not advance to review.
