Abstract
Ankle arthroplasty is increasingly used to treat advanced ankle arthritis. Earlier prostheses have given way to second-generation implants, on which we are accumulating medium-term data. The Scandinavian Total Ankle Replacement (STAR) is a three-component uncemented implant in wide use in Europe and the only mobile-bearing prosthesis with conditional approval in the United States. We retrospectively reviewed 45 patients (52 ankles) who had primary total ankle replacements using STAR prostheses, in order to assess survivorship and add to the pool of clinical data provided by independent practitioners required to establish this treatment as a viable alternative to arthrodesis. The minimum followup was 60 months (range, 60–110 months). Clinical outcome was determined using the AOFAS score. We determined the rate of radiographic loosening and recorded complications and the need for further surgery. Survival was 90% (95% CI 76.8 to 95.5) at 5 years and 84% (95% CI 68.9 to 92.2) at 8 years. Six of 52 ankles (11%) had component revision and two were converted to fusion. The mean postoperative AOFAS score was 78. The complication rate was 21%. Subsequent surgery, excluding component revision, was performed in nine of 52 (17%) ankles. Level of Evidence: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.Keywords
