RESUMO
BACKGROUND: Patients who undergo total ankle arthroplasty (TAA) for end-stage posttraumatic ankle osteoarthritis have previously reported more complications and lower satisfaction than those with non-traumatic etiologies. The purpose of this study was to evaluate clinical and radiographic outcomes in these two patient groups after TAA using a newer generation implant. METHODS: Patients underwent TAA with a third generation implant using CT-based patient-specific cutting guides. Patients were evaluated clinically using the Foot and Ankle Ability Measure (FAAM) and radiographically at a mean follow up of 32, and 24 months respectively. RESULTS: Forty-one patients were studied (26 posttraumatic, 15 nontraumatic). There were no significant differences between the two study groups in FAAM scores (p=0.3423) and radiographic measurements. CONCLUSION: We were able to show comparable results in terms of patient satisfaction, short term clinical and radiographic results between traumatic and nontraumatic patients using newer patient specific implant systems.
