Abstract
BackgroundPatients 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. MethodsPatients 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. ResultsForty-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. ConclusionWe 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.
