【原著】CLINICAL RESULTS AFTER TOTAL TALAR REPLACEMENT WITH ALUMINA CERAMIC PROSTHESIS EVALUATED USING SAFE-Q FOR OSTEONECROSIS OF THE TALUS

Abstract

Background: The purpose of this retrospective review was to evaluate the clinical outcomes of patients who underwent total talar replacement for talar necrosis using the SAFE-Q score, which was hypothesized to improve postoperatively. Methods: The study included 24 ankles of 22 patients who underwent total talar replacement from 2012 to 2018 and were evaluated using SAFE-Q preoperatively and postoperatively.Statistical analysis was performed using the mean values of the SAFE-Q and JSSF scale scores, and the range of ankle motion was compared before and 3 years after the surgery using the Wilcoxon signed-rank test. Results: The SAFE-Q scores improved postoperatively in all the subcategories.“Pain and Pain-Related" changed from a mean value of 42.2 ± 23.9 points preoperatively to a mean value of 84.6 ± 12.6 points postoperatively (p<.01);“Physical Functioning and Daily Living" changed from 36.3 ± 25.2 points to 73.4 ± 20.5 points (p<.01);“Social Functioning" changed from 34.1 ± 34.8 points to 81.0 ± 25.3 points (p<.01):“Shoe-Related"changed from 41.3 ± 28.9 points to 75.4 ± 22.3 points (p<.Ol); and "General Health and Well-Being" changed from 36.7 ± 32.1 to 76.9 ± 29.3 points (p<.01). Conclusion: Tenty-four osteonecrotic tali of 22 patients treated with alumina ceramic total talar replacement achieved good clinical results，as evaluated using the JSSF ankle/hindfoot score and SAFE-Q.Alumina ceramic total talar replacement is the mainstream treatment for talar osteonecrosis. Level of Evidence: Level Ⅳ, retrospective comparative study.
