Total Ankle Arthroplasty: Clinical and Radiographic Outcomes of a Case Series with 10-Year Follow-up
Abstract
Introduction: End-stage ankle osteoarthritis is a major cause of pain and disability. Total ankle arthroplasty (TAA) has emerged as an alternative to arthrodesis, aiming to preserve joint mobility and improve quality of life. However, long-term evidence remains limited. The objective of this study was to evaluate the clinical and radiographic outcomes of a series of patients who underwent TAA with a minimum follow-up of 10 years. Materials and Methods: A retrospective series of patients who underwent TAA between 2007 and 2015 was analyzed. Demographic data, pain assessed using the Visual Analog Scale (VAS), function assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score, quality of life assessed using the Short Form-36 (SF-36), radiographic findings, and implant survivorship were evaluated. Results: Out of 40 patients, 17 completed the 10-year follow-up. The median VAS score improved from 8 to 3 (p < 0.001). The AOFAS score increased from 36 to 79 points, reaching a maximum of 80 points at 5 years (p < 0.001). The SF-36 demonstrated good to very good results across most domains. Implant survivorship at 10 years was 82%. Conclusion: Total ankle arthroplasty provides sustained pain relief and improves function and quality of lifeat 10 years, supporting its role as a valid alternative to arthrodesis in patients with end-stage ankle osteoarthritis.Downloads
