Highlights¶

Syndesmosis Injury Fixation¶

Several articles address distal tibiofibular syndesmosis management, spanning novel fixation techniques and evidence on fixation methods. Arthroscopic-assisted adjustable progressive compression fixation combines rigid fixation strength with elastic compliance, allowing intraoperative tension adjustment [4], while needle arthroscopy-guided reduction with suture button fixation enables direct visualization to confirm anatomic reduction [9]. A cadaveric study validates fluoroscopic clamp placement methods along the transsyndesmotic axis, including effects of metal artefact [15]. A review of tightrope fixation summarizes evidence favoring suture-button devices over screws for diastasis, with lower malunion and fewer implant complications [26]. Finally, syndesmotic microinstability (<2 mm dynamic diastasis) accompanying ATFL injury did not compromise outcomes when left unfixed [27].

Lateral Ankle Instability Surgery¶

This theme covers arthroscopic management of chronic lateral ankle instability and lateral ligament repair. A modified all-inside arthroscopic anterior tibiofibular ligament repair with suture-based 'turn-back' reinforcement offers an augmentation option for poor-quality ligaments while avoiding stiffness from rigid bracing [8]. Return-to-sport outcomes after arthroscopic anatomic reconstruction with gracilis autograft show favourable RTS rates, with risk factors for recurrence identified in high-demand patients [22]. The debate over inferior extensor retinaculum reinforcement during arthroscopic Broström repair continues in correspondence, with letters noting that augmentation provides only modest early advantages without sustained superiority at final follow-up [16, 17].

Total Ankle Arthroplasty Outcomes¶

Total ankle replacement (TAR) research this month spans implant biomechanics, perioperative care, and registry data. Cadaveric robotic gait simulation demonstrated that stemmed tibial components exhibit less bone-implant micromotion than low-profile designs, supporting their association with lower early mechanical failure [3]. A prospective study of a fast-track protocol after TAR showed safe early mobilization, multimodal pain management, and improved short-term function [6]. Preoperative psychiatric medication use was associated with postoperative complication rates after total ankle arthroplasty in a large propensity-matched database cohort [2]. An 11-year French national registry cohort provides population-based survival data, examining revision risk by implant model, patient characteristics, and surgeon volume [29].

Osteochondral Lesions of Talus¶

Osteochondral lesions of the talus (OLT) are addressed from evolving treatment algorithms to long-term outcomes and prevention of progression. A state-of-the-art review outlines management strategies based on lesion size, morphology, subchondral bone involvement, and ankle stability, covering fragment fixation, bone marrow stimulation, and replacement procedures [10]. Autologous osteoperiosteal transplantation for cystic OLT showed that maximal outcome improvement thresholds predict satisfaction, with BMI and plug number influencing threshold achievement [7]. A perspective piece argues for earlier intervention in ankle cartilage damage, highlighting the posttraumatic pathway from sprain to end-stage osteoarthritis and the scarcity of evidence on nonoperative and biologic early treatments [12].

Achilles Tendon Pathology¶

Achilles tendon conditions feature across surgical innovation, cost-effectiveness, and sports epidemiology. A retrospective cohort comparing open central-splitting surgery with ultrasound-guided WALANT minimally invasive surgery for insertional Achilles tendinopathy found similar patient-reported outcomes at substantially lower cost [5]. A comprehensive review of insertional Achilles tendinopathy details etiology, pathophysiology including calcaneal prominence and impingement, and implications for treatment decision-making [25]. In elite sport, a 15-year analysis of NFL Achilles ruptures revealed preseason vulnerability, with temporal clustering of injuries across season phases informing prevention strategies [23].

Fracture Care and Education¶

This theme captures ankle fracture management, related periarticular trauma, and education. Osteoporosis was shown to be an independent risk factor for adverse outcomes after ankle open reduction and internal fixation in adults over 50, using a large propensity-matched database [14]. Video-assisted resident education improved ankle joint reduction quality in a prospective controlled study, supporting simulation-based training [24]. A current concepts review of acute intra-articular calcaneal fractures discusses minimally invasive techniques for restoring hindfoot alignment and articular congruity [19]. Navicular fractures in elite athletes prompted a methodological critique of the 2025 international consensus, recalculating return-to-sport timelines [13]. Pickleball and tennis injury trends from emergency department data round out the sports trauma picture [28].

Articles by Theme¶

Syndesmosis Injury Fixation (5)¶

4. Li K, Chen Y, Guo Q, et al. Arthroscopic‐Assisted Adjustable Progressive Compression Fixation for Distal Tibiofibular Syndesmosis Injury. Arthroscopy Techniques 2026. doi:10.1002/atn2.70336

This technical note describes an arthroscopic-assisted adjustable progressive compression fixation technique for distal tibiofibular syndesmosis injuries, using rotation of a fibular-side EndoButton to twist and shorten 4-strand high-tensile sutures. It combines rigid-fixation strength with elastic-fixation compliance, allowing real-time tension adjustment under arthroscopic and fluoroscopic visualization. This avoids the drawbacks of screw fixation (micromotion restriction, hardware removal) and nonadjustable elastic constructs.

9. Wójtowicz BG, Chlebanowski B, Taborski G, et al. Needle Arthroscopy‐Guided Anatomic Reduction and Suture Button Fixation of the Distal Tibiofibular Syndesmosis. Arthroscopy Techniques 2026. doi:10.1002/atn2.70332

The authors describe a surgical technique using needle arthroscopy to directly visualize the distal tibiofibular syndesmosis during anatomic reduction and suture button fixation, with a four-cortex trans-syndesmotic tunnel created under fluoroscopic guidance and reduction confirmed in real time. Direct arthroscopic visualization may detect rotational and subtle translational malalignment that fluoroscopy alone can miss. This approach could lower the risk of syndesmotic malreduction while minimising soft-tissue disruption.

15. Nakajima H, Kimura S, Yamaguchi S, et al. Validity of fluoroscopic methods along the transsyndesmotic axis: A cadaveric study. Injury 2026. doi:10.1016/j.injury.2026.113629

In ten fresh-frozen cadaveric feet, the authors compared three fluoroscopic clamp placement methods for syndesmotic fixation (center-center, talar dome lateral, and incisura tangent) against the true transsyndesmotic axis, both with and without fracture fixation implants in place. The study quantified interaxis angle and distance deviations for each method and the effect of metal artifact. Findings guide surgeons in selecting the most accurate fluoroscopic landmark for clamp and screw placement during syndesmotic fixation.

26. Keating J. Tight rope fixation in fracture management. Injury 2026. doi:10.1016/j.injury.2026.113530

This review examines the evolution of tightrope (suture-button) fixation since its 2005 introduction as an alternative to syndesmosis screws in ankle fractures with diastasis. Published evidence suggests tightrope fixation achieves effective syndesmotic stabilisation with lower malunion rates, fewer implant complications, reduced need for implant removal, and in some trials better functional outcomes than screws. The technique has also proven effective for lateral third clavicular fractures and acromioclavicular dislocations, alone or combined with plating.

27. Shi P, Wei Y, Liu M, et al. The Impact of Distal Tibiofibular Syndesmosis Microinstability on Functional Outcomes in Patients With Anterior Talofibular Ligament Injury Surgery. Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261467551

This retrospective cohort study evaluated whether untreated syndesmotic microinstability (dynamic diastasis <2 mm, identified arthroscopically) affects outcomes after isolated ATFL surgery without syndesmotic fixation. Patients with microinstability were compared to those with intact syndesmoses using Karlsson-Peterson, FAAM, and Tegner scores over follow-up. The findings clarify the clinical significance of subtle syndesmotic widening below the traditional 2-3 mm instability threshold in lateral ankle instability surgery.

Lateral Ankle Instability Surgery (4)¶

8. Hou H, Wang F, Hong J, et al. Modified All‐Inside Arthroscopic Anterior Tibiofibular Ligament Repair and Reinforcement in Chronic Ankle Instability. Arthroscopy Techniques 2026. doi:10.1002/atn2.70256

A modified all-inside arthroscopic technique for chronic ankle instability is described, using individualized portal placement and lasso-loop suturing of the anterior talofibular ligament with a flexible turn-back suture augmentation. The approach provides anatomic repair and enhanced stability in cases with poor ligament quality while avoiding the joint stiffness risk of rigid internal bracing.

16. Lee SH, Lim GH, Kang HT, et al. Efficacy of Inferior Extensor Retinaculum Reinforcement in Arthroscopic Ankle Lateral Ligament Repair: Response. The American Journal of Sports Medicine 2026. doi:10.1177/03635465261470332

In this response to a letter, the authors note that two of their earlier studies addressed the same question as a recent randomised trial of inferior extensor retinaculum (IER) reinforcement during arthroscopic Brostrom repair, with similar findings. Both prior studies showed equivalent 24-month functional outcomes, with IER augmentation offering only modest early advantages at 3 and 6 months. The available evidence suggests routine IER augmentation provides no sustained long-term benefit over isolated arthroscopic ligament repair.

17. Maffulli N, Spiezia F, Oliva F, et al. Efficacy of Inferior Extensor Retinaculum Reinforcement in Arthroscopic Ankle Lateral Ligament Repair: Letter to the Editor. The American Journal of Sports Medicine 2026. doi:10.1177/03635465261470347

In this letter to the editor, the authors respond to a randomised trial of arthroscopic lateral ankle ligament repair with versus without inferior extensor retinaculum (IER) reinforcement by citing two earlier studies from their group. Those studies found that IER augmentation offered only a modest early functional advantage (at 3-6 months) with no sustained benefit at 24 months, whether compared with isolated Broström repair or semitendinosus autograft reconstruction. Clinically, this suggests IER reinforcement provides limited long-term added value and should be weighed against the findings of the new randomised trial.

22. Moussa MK, Bogdan P, Valentin E, et al. Return to Sport and Risk Factors for Recurrence After Arthroscopic Anatomic Lateral Ankle Ligament Reconstruction. Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261486661

This case-control study evaluated 101 patients undergoing arthroscopic anatomic lateral ankle ligament reconstruction with gracilis autograft for chronic lateral ankle instability, with minimum 2-year follow-up. It assessed return-to-sport rates and timing, functional outcomes (FAAM scores), and risk factors for recurrence and rerupture using multivariate regression. The findings inform patient counseling and identification of high-risk patients after arthroscopic autograft reconstruction in high-demand populations.

Total Ankle Arthroplasty Outcomes (4)¶

2. Martino JA, Pottanat P, Cave S, et al. Association of Preoperative Psychiatric Medication Use With Complication Rates After Total Ankle Arthroplasty. Journal of the American Academy of Orthopaedic Surgeons 2026. doi:10.5435/jaaos-d-26-00140

Using the TriNetX database, patients undergoing total ankle arthroplasty were stratified by preoperative psychiatric medication use and compared after 1:1 propensity score matching (1,164 patients per cohort). The study assessed postoperative medical and surgical complications at follow-up. The findings inform perioperative risk stratification and counseling for TAA patients with psychiatric medication exposure.

3. Henry JK, Hoffman J, Villar R, et al. Implant Choice Impacts Initial Tibial Component Micromotion in Total Ankle Replacement. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.26.00733

In 10 matched cadaveric pairs implanted with either a low-profile or stemmed total ankle replacement tibial component, gait was simulated with a 6-DOF robot and bone-implant micromotion was measured using digital image correlation with CT-derived rigid-body transformations. The hypothesis was that stemmed designs provide more robust fixation and less interface micromotion. Results bear on implant selection to reduce early mechanical failure risk in TAR.

6. Vena LM, Moggio L, Cofano E, et al. Clinical outcomes and feasibility of a fast-track protocol after total ankle replacement: a prospective study. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06532-9

A prospective observational study of 22 consecutive primary total ankle replacements evaluated a fast-track protocol including early mobilization, multimodal pain management, bleeding control, and structured physiotherapy with standardised discharge criteria. Outcomes included AOFAS scores at discharge, time to mobilization and ambulation, length of stay, and ASEPSIS wound scores. The study demonstrates the feasibility and short-term safety of fast-track recovery after total ankle replacement.

29. Besse J, Huot L, Judet T, et al. Outcomes of 11 years of total ankle replacement registry in France: a national population-based cohort study. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104981

This nationwide French registry cohort study analyzed all primary and revision total ankle replacements performed between 2012 and 2023 (~500/year nationally), assessing implant survival by model, patient characteristics, and surgeon case volume, alongside 2-year clinical and radiological outcomes. The study addresses concerns about osteolysis, subsidence, and worse results in low-volume surgeons. Findings provide comprehensive population-based benchmark data on TAR survival and outcomes in France.

Osteochondral Lesions of Talus (3)¶

7. Hu F, Yang S, Shao Q, et al. Maximal Outcome Improvements Predict Patient Satisfaction After Autologous Osteoperiosteal Transplantation for Cystic Osteochondral Lesions of the Talus, With Body Mass Index and Plug Number Associated With Threshold Achievement. Arthroscopy 2026. doi:10.1002/arj.70651

In patients with Hepple V cystic osteochondral lesions of the talus treated with autologous osteoperiosteal transplantation (minimum 24-month follow-up), maximal outcome improvement (MOI) thresholds for AOFAS, VAS, AAS, and FAOS were derived using ROC analysis against an anchor question on satisfaction. MOI predicted patient satisfaction, with BMI and number of plugs associated with threshold achievement. These thresholds aid postoperative counseling and benchmarking of surgical success.

10. Rubin J, Tham A, Gauthier P, et al. Evolving Management Strategies for Osteochondral Lesions of the Talus. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.25.01591

This review synthesizes current management of osteochondral lesions of the talus, stratifying treatment by lesion size, morphology, cartilage integrity, subchondral bone involvement, and ankle stability. Fragment fixation is favored in acute lesions with viable fragments, bone marrow stimulation for small contained lesions, and osteochondral autograft or allograft transplantation for larger or complex lesions. Clinicians should match the operative strategy to lesion characteristics, recognizing the variable long-term durability of fibrocartilage after marrow stimulation.

12. Hollander JJ, Dahmen J, Murawski CD, et al. From Sprain to End-Stage Osteoarthritis: Why Earlier Intervention in Ankle Cartilage Damage Deserves More Attention. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.26.00827

This perspective highlights that posttraumatic ankle osteoarthritis imposes a health burden comparable to major chronic diseases and predominantly affects young, active patients, yet evidence for nonoperative and early interventions remains limited and methodologically weak. Because the posttraumatic pathway allows study of disease progression from cartilage injury to end-stage arthritis, early recognition and treatment represent the greatest opportunity to alter long-term outcomes. Clinicians should prioritise early identification of ankle cartilage damage and initiation of treatment rather than waiting for advanced disease.

Achilles Tendon Pathology (3)¶

5. Lindén L, Alfredson H, Mohaddes M, et al. Transition from open surgery to ultrasound-guided minimally invasive surgery for insertional Achilles tendinopathy: similar patient-reported outcomes and substantially lower treatment costs. BMC Musculoskeletal Disorders 2026. doi:10.1186/s12891-026-10631-4

In a retrospective historical cohort of 52 patients with insertional Achilles tendinopathy, outcomes after open central-splitting surgery (n=20) were compared with ultrasound/colour Doppler-guided WALANT minimally invasive surgery (n=32), with 12-month SEFAS as the primary outcome. Patient-reported outcomes were similar between approaches, while the minimally invasive pathway incurred substantially lower treatment costs. This supports the transition to ultrasound-guided WALANT surgery in routine practice.

23. Kress DJ, Waldron P, Han D, et al. Seasonal Clustering of Achilles Tendon Ruptures in the NFL: A 15-Year Analysis Revealing Preseason Vulnerability. Orthopaedic Journal of Sports Medicine 2026. doi:10.1177/23259671261488665

This descriptive epidemiological study analyzed Achilles tendon ruptures among NFL players from 2010 to 2024 using publicly available data, stratifying injuries across season phases through multiple temporal models. The analysis revealed seasonal clustering with heightened vulnerability during the preseason period. These findings suggest that conditioning and workload patterns early in the season may elevate rupture risk, informing injury-prevention strategies in professional football.

25. Elkaïm M. Insertional Achilles tendinopathy State of pathology: Insertional tendon tendinopathies. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104974

This narrative review synthesizes the etiology, pathophysiology, and diagnosis of insertional Achilles tendinopathy, emphasizing its multifactorial origins (calcaneal prominence, biomechanical factors, footwear, metabolic causes) and the variable contributions of true enthesopathy versus posterior bone-tendon impingement with bursitis. Pain location, median for insertional tendinopathy versus more lateral for impingement, helps distinguish the two entities clinically. This distinction is deemed crucial for guiding appropriate treatment decisions.

Fracture Care and Education (5)¶

13. Zimmermann FJ, Amling M, Simon A. Navicular fractures in elite athletes: Clarifying the evidence base of the 2025 International Foot and Ankle Sports Consensus. Knee Surgery, Sports Traumatology, Arthroscopy 2026. doi:10.1002/ksa.70632

The authors critique the 2025 International Foot and Ankle Sports Consensus systematic review on navicular fractures in elite athletes, identifying methodological and reporting errors. Recalculation shows mean return to sport after operative treatment of navicular stress fractures is approximately 19.7 weeks (4.5 months), not the reported 8.2 weeks, consistent with the consensus recommendation of 4-6 months; several included studies also violated eligibility criteria. Return-to-sport counseling should rely on the corrected estimate of roughly 4-6 months after surgery.

14. Guruprasad P, Sivaram P, O’Neill C, et al. Impact of osteoporosis on outcomes following ankle open reduction and internal fixation. Injury 2026. doi:10.1016/j.injury.2026.113474

This retrospective propensity-matched cohort study using the TriNetX database compared postoperative outcomes after ankle fracture ORIF in adults aged 50 years or older with and without a prior osteoporosis diagnosis. The study was designed to determine whether osteoporosis is an independent risk factor for complications such as malunion, nonunion, and delayed healing. Results inform perioperative risk stratification and the need for bone health optimization in older patients undergoing ankle fracture fixation.

19. Lucas y Hernandez J. Acute intra-articular calcaneal fractures: currents concepts. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104916

This review summarizes current concepts in acute intra-articular calcaneal fractures, which most often involve the subtalar joint after high-energy trauma and carry substantial functional and socio-occupational consequences. Anatomical assessment guides prognosis, with CT as the reference standard for characterization and planning, while minimally invasive techniques (sinus tarsi approach, percutaneous fixation, intramedullary nailing) have shifted the surgery-versus-conservative debate. Displaced Sanders II-III fractures are the main indication for osteosynthesis, whereas Sanders IV fractures typically warrant discussion between ORIF and primary subtalar arthrodesis.

24. Bilodeau RE, Hall AJ, Como M, et al. Video-Assisted Resident Education is Associated with Improved Ankle Joint Reduction: A Prospective Controlled Study. Injury 2026. doi:10.1016/j.injury.2026.113823

This prospective controlled study evaluated whether video-assisted education improved ankle joint reduction quality among orthopaedic residents. Residents receiving video-based instruction achieved superior ankle reduction outcomes compared with controls. The results support incorporating video-assisted teaching into residency curricula to improve procedural competence in ankle fracture management.

28. Kiehl D, Ibrado R, Axelrod A, et al. Comparative Trends of Musculoskeletal Injury in Pickleball and Tennis: An 11-Year Analysis of U.S. Emergency Department Visits. Injury 2026. doi:10.1016/j.injury.2026.113791

This 11-year analysis of U.S. emergency department visits compared musculoskeletal injury trends between pickleball and tennis, capturing the surge in pickleball participation. The study characterizes injury patterns, rates, and temporal trends across the two racquet/paddle sports at the population level. Results inform injury prevention strategies and resource planning as pickleball-related injuries continue to grow.
