title: Analysis of ankle range of motion and functional outcome following total ankle arthoplasty.
abstract: The success of ankle joint replacement has primarily been reviewed with respect to patient morbidity and survivorship rather than patient satisfaction. A retrospective review was performed of 95 patients who had undergone a total ankle replacement and who had completed both postoperative range of motion fluoroscopy and a subjective patient score sheet. Collected data included age, body mass index, length of follow-up, presence of complications, performance of adjunctive procedures, range of motion, and the etiology of the end-stage arthritis. These variables were then compared with patient satisfaction to see if there were any predictive conditions of successful outcomes. Patients older than 60 years and those with a body mass index (BMI) less than 30 demonstrated a significant positive association with subjective satisfaction scores (P = .0023 and .0008, respectively). The amount of postoperative range of motion did not appear to correlate with patient satisfaction. Furthermore, there were no significant associations of patient satisfaction with a patient age younger than 60 years, a BMI greater than 30, additional procedures, perioperative complications, the length of time after surgery, and the presenting etiology.
