Association of Preoperative Depression Score With Outcomes of Transfibular Total Ankle Arthroplasty

Favorable short-term results of transfibular total ankle arthroplasty have been reported in several studies; however, the factors affecting these results have not been elucidated. This study aimed to determine whether preoperative depression affects the outcome of transfibular total ankle arthroplasty and whether depression changes with surgery. Scores from the Japanese Society of Surgery of the Foot Ankle/Hindfoot scale (JSSF scale), Self -Administered Foot Evaluation Questionnaire (SAFE-Q), Hospital Anxiety and Depression Scale (HADS), and Timed Up & Go test (TUG) were collected preoperatively, at 6 months, and at 1 year postoperatively from 20 patients. Eighteen patients were diagnosed with osteoarthritis and 2 patients with rheumatoid arthritis. The mean age of the patients was 75 years. Patients were divided into 2 groups: those with preoperative HADS depression scores above the median (higher depression score group) and below the median (lower depression score group), and intergroup comparisons were made. No significant differences were observed in the JSSF and TUG scores between the groups, both preoperatively and postoperatively. Meanwhile, the SAFE-Q pain subscale score was significantly lower in the higher depression score group than in the lower depression score group (median, 59 vs 90) 1 year postoperatively. There were no differences in the other SAFE-Q subscale scores between the groups. The results suggested that depressive tendencies did not affect postoperative functional results using objective assessment measures but had a negative impact on pain in subjective assessment measures.
