Predictors of Limited Weight-Bearing Dorsiflexion Following Total Ankle Arthroplasty.
Preoperative clinical dorsiflexion is the only independent predictor of postoperative dorsiflexion after total ankle arthroplasty; patient counseling should address realistic motion expectations.
In this registry cohort, preoperative anxiety/depression was common before total ankle arthroplasty but did not independently predict worse 12-month patient-reported outcomes, and most patients' symptoms resolved postoperatively.
At five-plus years, combining subtalar arthrodesis with transfibular total ankle arthroplasty produced functional, pain, and radiological outcomes comparable to isolated total ankle arthroplasty, supporting its safety in select patients.
In a cadaveric-model study, computer-assisted navigation gave the most accurate tibial cuts while patient-specific instrumentation was best for talar cuts, both outperforming conventional fluoroscopic instrumentation in total ankle arthroplasty.
In this multicenter study of 502 Infinity total ankle arthroplasties, preoperative COFAS deformity grade did not affect 5-year survivorship, complications, or patient-reported outcomes, supporting its use even in complex cases.
Fixed-bearing total ankle arthroplasty improved quality of life and pain at mean 6-year follow-up, with outcomes exceeding clinically important thresholds.
Salto Talaris total ankle arthroplasty achieves 86.9% implant survivorship at 15 years with sustained pain improvement and functional gains.
In 1008 total ankle arthroplasties, prosthetic joint infection occurred in 2.7% of cases, with concomitant calcaneal displacement osteotomy raising infection risk nearly 10-fold, though most cases achieved limb salvage with contemporary treatment.
In 631 total ankle replacements, a predictive model using baseline AOS score and instability etiology (AUC 0.76) helps identify patients likely to achieve clinically meaningful improvement, aiding preoperative counseling.
Malnutrition is associated with poor outcomes following total ankle arthroplasty.
Preoperative malnutrition markers (low transferrin, albumin, or leukocytes) were linked to higher short-term complications and worse 5-year outcomes after total ankle arthroplasty, highlighting a modifiable risk factor.
In 164 primary total ankle arthroplasties, FAAM-ADL MCID thresholds ranged from 12.5 to 32.3 points depending on method, with lower baseline function predicting MCID achievement.
Five-year major amputation rate after total ankle arthroplasty is 0.60% overall but 0.98% in diabetic patients, significantly higher than non-diabetic patients.
BMI-based eligibility cutoffs for TAA would deny 27 complication-free surgeries to prevent one complication, suggesting BMI alone is insufficient for surgical exclusion.
Transfibular total ankle arthroplasty shows favorable midterm outcomes in younger patients comparable to older patients, suggesting broader candidacy across age ranges.
The SALTO TALARIS total ankle arthroplasty demonstrates excellent long-term reliability with 96.2% metallic component survival and 99% arthrodesis-free survival at 10 years minimum follow-up.
Lower baseline pain severity and greater talar tilt angle predict surgical selection in advanced varus ankle osteoarthritis initially treated conservatively with insoles.
Extended-length tibial tray in total ankle arthroplasty reduced heterotopic ossification, maintained functional outcomes, and improved patient satisfaction versus standard design.
Management of the failing ankle arthroplasty : an algorithm to assist decision-making.
Proposes a structured, multidisciplinary algorithm for evaluating and managing failing total ankle arthroplasty, emphasizing infection screening, imaging, and alignment/bone stock assessment.
This review covers ankle osteoarthritis, noting most cases are posttraumatic, and discusses conservative care versus surgical options like arthrodesis and total ankle arthroplasty.
Diagnosis and Management of Periprosthetic Joint Infections After Total Ankle Arthroplasty.
A review outlining risk factors, diagnostic workup, and staged surgical management (debridement, two-stage revision, arthrodesis, amputation) for periprosthetic joint infection after total ankle arthroplasty.
Comparative Studies of Bone Graft and Orthobiologics for Foot Ankle Arthrodesis: A Critical Review.
Bone grafts and orthobiologic agents show variable efficacy for ankle/hindfoot arthrodesis; limited comparative evidence exists to guide material selection.
Outcomes of Total Ankle Replacement with Preoperative Varus Deformity.
Total ankle replacement with severe varus deformity achieves good outcomes when corrective procedures applied, though complications increase with deformity severity.
Diagnosing and Managing Infection in Total Ankle Replacement.
Early TAR infections respond to debridement with polyethylene exchange; late infections require implant removal and two-stage revision with antibiotic spacer.
Metal artifact reduction MRI techniques accurately identify total ankle arthroplasty complications including osteolysis, infection, fractures, and soft-tissue injuries when radiography is inconclusive.
Total ankle arthroplasty alters gait mechanics and provides pain relief as an alternative to fusion for ankle arthritis management.
Prospective Controlled Trial of STAR Total Ankle Replacement versus Ankle Fusion: Initial Results
Mobile-bearing STAR ankle replacement showed better functional outcomes and equivalent pain relief compared to fusion through 24 months of follow-up.
A Review of Ankle Arthrodesis: Predisposing Factors to Nonunion
Reviewing 78 ankle fusions over 15 years, nonunion was linked to fracture type, avascular necrosis, infection, major comorbidities, and open injury, but not age or prior hindfoot fusion.
Evidence-Based Classification of Complications in Total Ankle Arthroplasty
Literature review of 20 studies proposes a grading system classifying total ankle arthroplasty complications (e.g., infection, loosening as high-grade) to guide postoperative management.
