Background: Treatment of osteonecrosis of the talus is challenging. Nonoperative management includes nonweightbearing treatment. Various types of hindfoot fusion procedures have been performed, but delayed union and shortening of the operated leg have reportedly occurred. In contrast, talar body prosthesis is a surgical procedure with potential that relieves pain, restores ankle joint function, and is not associated with leg-length discrepancy. The aim of this study was to investigate postoperative pain, clinical outcomes, activities of daily living (ADL), and quality of life (QOL) after total talar replacement in patients with osteonecrosis of the talus. Methods: Ten ankles in 10 patients with idiopathic osteonecrosis of the talus who were treated with a total talar replacement between 2007 and 2015 were included in the investigation. Scores according to the visual analog scale (VAS), Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, Functional Independence Measure (FIM), and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were assessed. Results: The VAS score significantly improved from a mean of 80 ± 8 points before surgery to 18 ± 22 points after surgery (P <.01). The JSSF ankle-hindfoot scale score significantly improved from a mean of 53 ± 12 points before surgery to 89 ± 7 points after surgery (P <.01). The FIM score significantly improved from a mean of 122 ± 1 points before surgery to 125 ± 1 points after surgery (P <.01). The mean postoperative SAFE-Q scores were as follows: 81 ± 10.3 points for pain, 78 ± 14.7 points for physical function, 90 ± 12.4 points for social function, and 83 ± 15.4 points for shoe-related. Conclusion: Total talar replacement is a useful treatment for patients with osteonecrosis of the talus. This replacement surgery preserves the function of the ankle and subtalar joints, and improves pain, ADL, and QOL. Level of Evidence: Level IV, case series. [ABSTRACT FROM AUTHOR]
