About this Research Topic

Background

Lateral ankle sprains (LAS) are among the most common musculoskeletal injuries, particularly in physically active individuals and athletes, with an incidence rate of approximately 1.94 per 1,000 individuals among young adults. While often perceived as minor injuries, the consequences of LAS can be long-lasting and severe. Following an initial LAS, about 40% of individuals would ultimately develop chronic ankle instability (CAI), characterized by recurring episodes of the ankle "giving way," persistent instability, and recurrent ankle sprains. Even worse, up to 78% of individuals with CAI may further progress to ankle post-traumatic osteoarthritis (PTOA), leading to chronic pain, functional limitations, work loss, and a diminished quality of life. Thus, unraveling the mechanisms and exploring effective management approaches for LAS, CAI, and ankle PTOA is of paramount importance.

Individuals with LAS, CAI, and ankle PTOA often suffer from a wide range of impairments, including pathomechanical deficits (e.g., ligament laxity, decreased range of motion, cartilage degradation), sensorimotor deficits (e.g., reduced proprioception and strength, poor postural control, altered biomechanics), and psychosocial factors (e.g., decreased self-efficacy, fear of movement). These impairments interact and compound, not only compromising sports performance but also affecting daily living activities, leading to decreased health-related quality of life. Obviously, understanding the pathological progression through LAS, CAI, and ankle PTOA, and their contributing factors is crucial for developing comprehensive approaches that enhance recovery outcomes, reduce injury and re-injury risk, prevent disease progression, and improve overall function and quality of life.

Despite the robust literature surrounding the impairments and disabilities associated with ankle sprains, significant gaps remain. Therefore, there is an obvious need for a platform where we can continue advancing our understanding of the underlying mechanisms, explore innovative injury prevention strategies, and establish effective clinical management paradigms that mitigate long-term consequences for ankle sprain-related medical problems.

This Research Topic aims to collect cutting-edge research on LAS, CAI, and ankle PTOA, focusing on their injury mechanisms and prevention and rehabilitation strategies. The goal is to foster interdisciplinary collaboration among researchers, sports medicine clinicians, physiotherapists, athletic trainers, and sports psychologists to enhance our understanding and management of LAS, CAI, and ankle PTOA. Ultimately, translating research findings into practical interventions that improve patient outcomes, reduce recurrence rates of ankle sprains, prevent the development and progression of ankle osteoarthritis, and support sustained engagement in sports and active lifestyles.

We invite researchers and clinicians to submit original research articles, systematic reviews (with or without meta-analyses), brief research reports, case studies, commentaries, opinions, and hypotheses or theoretical papers that explore various aspects of LAS, CAI, and ankle PTOA. Submissions may cover, but are not limited to, the following topics:

1. Epidemiology and Population Studies: Exploration of the prevalence, incidence, and economic burden of LAS, CAI, and ankle PTOA across different age groups, genders, and activity levels.
2. Injury Mechanisms and Risk Factors: Investigations into the pathomechanical, sensorimotor, and psychosocial mechanisms, and their interactions that lead to LAS, the development of CAI, and progression to ankle PTOA.
3. Disease Subdivision and Precision Management: Classification and staging of LAS, CAI, and ankle PTOA based on patient characteristics, imaging findings, and biomarker profiles to tailor personalized clinical management approaches.
4. Diagnostic and Assessment Techniques: Methodological development and validation of new diagnostic methods for early detection of LAS, CAI, and ankle PTOA, as well as their associated risk factors.
5. Injury Prevention Strategies: Research on strategies to reduce the initial incidence of LAS and prevent progression to CAI and osteoarthritis.
6. Rehabilitation and Therapeutic Interventions: Development and evaluation of protocols aimed at restoring function, preventing recurrence, and slowing osteoarthritis progression after the initial LAS.
7. Clinical Practice Opinions, Consensus or Guideline: Establishment of criteria to define full recovery or safe return to daily life, work, or sport after LAS, CAI, and ankle PTOA.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.
