Second-generation total ankle arthroplasty has been reported to have good intermediate-term results. The purpose of the present study was to report on the cause and frequency of reoperation and failure after total ankle arthroplasty and to determine demographic and clinical predictors of reoperation and failure. Eighty-five patients (28%) underwent 127 reoperations (involving 168 procedures) after primary total ankle arthroplasty. The most common procedures at the time of reoperation were débridement of heterotopic bone (fifty-eight), correction of axial malalignment (forty), and component replacement (thirty-one). Eight patients underwent below-the-knee amputation. Age was found to be the only significant predictor of reoperation and failure after total ankle arthroplasty. The five-year survival rate with reoperation as the end point was 54%. The five-year survival rate with failure as the end point was 80% for all patients and 89% for patients who were more than fifty-four years of age. The prosthesis could not be salvaged in nine ankles (2.9%); the inability to salvage the prosthesis was most often due to loosening or infection. We noted a relatively high rate of reoperation after total ankle arthroplasty with this second-generation device. Younger age was found to have a negative effect on the rates of reoperation and failure. Most prostheses could be salvaged; however, the functional outcome of this procedure is uncertain.
