Abstract
BACKGROUND: Total ankle arthroplasty is often not recommended to younger patients with ankle arthritis because of their high functional demands. The purpose of this study was to compare intermediate-term clinical and radiographic outcomes and survivorship rates of total ankle arthroplasty between patients younger and older than 55 years. METHODS: A total of 117 consecutive patients (123 ankles) who underwent primary total ankle arthroplasty using Hintegra prosthesis with a mean follow-up of 78 months were enrolled and divided into 2 age groups: under 55 years (38 ankles; mean age 45 years) and over 55 years (85 ankles; mean age 65 years). RESULTS: Clinical scores of Ankle Osteoarthritis Scale pain and disability, American Orthopaedic Foot & Ankle Society ankle-hindfoot, Short Form-36 Physical Component Summary and Mental Component Summary, and visual analog scale were not significantly different between the 2 age groups at the final follow-up (P > .05). There were no significant differences in complications and survivorship rates between the two at a mean follow-up of 78 months (P > .05). CONCLUSIONS: Clinical and radiographic outcomes and survival rates of total ankle arthroplasty in patients under age of 55 years were satisfactory and comparable to those in patients older than 55 years in the intermediate-term follow-up. Therefore, total ankle arthroplasty may be considered as a viable treatment option in young patients with end-stage ankle arthritis. LEVEL OF EVIDENCE: Level III, comparative series, therapeutic.
