Researchers prospectively collected data for 23 ankles that were converted to total ankle arthroplasty after tibiotalar arthrodesis. Investigators used the SF-36, VAS and Short Musculoskeletal Function Assessment to assess patient-reported health and function. A goniometer was used to clinically evaluate ankle range of motion. Radiographs were evaluated twice by two foot and ankle surgeons during initial weight-bearing and at the last follow-up. The mean follow-up was 33.1 months.
Here are seven takeaways:
1. Findings showed the mean preoperative VAS score improved about 47 points from preoperative evaluation to the most recent follow-up.
2. Five patients were pain free and eight patients had a VAS score of less than 10.
3. SF-36 scores also improved from 37.7 to 56.4.
4. The mean SMFA bother index score improved from 55 preoperatively to 30.6 postoperatively.
5. The mean function index also improved from 46.7 to 25.4.
6. Investigators noticed an implant survival rate of 87 percent.
7. Overall, 43 percent of patients experienced minor complications that did not need surgery.
