Unlabelled: Besides the acute injury and trauma-induced macroscopic alterations, the evolution to posttraumatic ankle osteoarthritis (PTOA) is a complex process progressing at the tissue and molecular level. Furthermore, changes in the molecular pathways affect chondrocyte viability. Treatment modalities for PTOA focal or confined disease include innovative techniques.

Objective: Our purpose is to increase medical awareness based on scientific evidence of pathophysiology, molecular biology, and treatment of post-traumatic ankle osteoarthritis.

Methods: To support the perspectives of the experts, evidence from the scientific literature respected the PRISMA guidelines and the PICOS search strategy was used. We included case-control, cohort, experimental studies and case reports, written in English.

Results: The authors were homogeneously exposed to 282 selected abstracts and 114 full articles directly related to post-traumatic osteoarthritis after malleolar fractures.

Conclusion: The pathophysiological factors involved in posttraumatic ankle osteoarthritis, such as biological, structural, mechanical, and molecular changes must be studied together, as the interaction between these factors determines the risk of progression of PTOA. Inhibition of a single catabolic molecule or cascade probably is not sufficient to alter the natural progression of the pathological process.

Survey of Utilization of Weightbearing Computed Tomography Within AOFAS Membership.

Foot Ankle Spec

December 2024

Division of Orthopedic Foot and Ankle Surgery, Department of Orthopaedic Surgery, Duke University, Durham, North Carolina.

Background: Weightbearing computed tomography (WBCT) has been increasingly employed to evaluate and treat patients with varied pathologies such as progressive collapsing foot deformity (PCFD), posttraumatic deformity, hallux valgus, ankle arthritis, Charcot arthropathy, lisfranc, and syndesmosis injuries. However, little is known regarding its overall availability to foot and ankle providers and how it is being used in clinical practice. The goal of this study is to assess the utilization of WBCT among AOFAS members, identify the indications for use in clinical practice and potential barriers for implementation.

Influence of custom dynamic orthoses on tibiotalar joint reaction force and contact stress: A cadaveric study.

J Biomech

December 2024

Department of Orthopedics and Rehabilitation, University of Iowa, 200 Newton Road, Iowa City, IA 52242, United States; Department of Biomedical Engineering, University of Iowa, 200 Newton Road, Iowa City, IA 52242, United States. Electronic address:

Article Synopsis
  • Post-traumatic osteoarthritis (PTOA) often arises after tibial pilon fractures, leading surgeons to prioritize precise articular reduction, which can extend surgery time.
  • A cadaveric study explored how the stiffness of custom dynamic orthoses (CDOs) affects ankle joint reaction force (JRF) and contact stress during the stance phase of walking.
  • Results showed that using CDOs reduced JRF by up to 32%, indicating that post-operative bracing could lower the risk of developing PTOA after such fractures.

Nonunion in Foot and Ankle Arthrodesis Surgery: Review of Risk Factors, Identification of High-risk Patients, and a Guide to Perioperative Testing and Optimization.

J Am Acad Orthop Surg

November 2024

From the Department of Surgery, Section of Orthopaedic Surgery, University of Calgary, Calgary, Alberta, Canada (Greene, Dodd, Le, and LaMothe), and the Department of Surgery, Division of Orthopaedic Surgery, Memorial University, St. John's, Newfoundland and Labrador, Canada (Greene).

Foot and ankle arthrodesis surgery is often associated with high rates of nonunion ranging from 8% to 40%. This complication can result in individual patient burden and system burden in the management of these complex patients. Biologic factors contribute greatly to the development of a nonunion, including patient-related modifiable risk factors, metabolic and endocrine factors, systemic disease, previous surgeries, medications, weight loss treatments, and posttraumatic and postsurgical factors.

Intra-articular ankle fracture (IAF) often leads to post-traumatic osteoarthritis (PTOA), resulting in significant long-term morbidity. While previous research has focused on the inflammatory cytokines and matrix metalloproteinases within the synovial fluid fracture hematoma (SFFH), the immune cell populations within SFFH that contribute to PTOA development remain underexplored. This study aimed to characterize the immune cell populations in SFFH to better understand their role in the inflammatory response and potential for inducing lasting cartilage damage.

Anterior ankle impingement.

Orthop Traumatol Surg Res

Clinique de l'Orangerie, 29 allée de la Robertsau, 67000 Strasbourg, France. Electronic address:

Our understanding of the pathophysiology of anterior ankle impingement has steadily progressed since the princeps description almost 70 years ago. The same is true of diagnosis and treatment, which have greatly changed over time. The present study provides an update on this pathology, addressing the following questions: Anterior ankle impingement is suspected in case of anterior ankle pain reproducible by palpation and exacerbated by dorsiflexion imposed by the examiner or squatting, and Molloy's sign.
