The purpose of the present study was to identify changes in the range of motion during the first year after placement of the Salto-Talaris total ankle implant. The first 97 cases were assessed throughout the year at 6 weeks and 3, 6, and 12 months. Data were extracted through retrospective chart review, operative reports, and electronic goniometry of the implant in maximal dorsiflexion and plantarflexion. The range of motion incrementally improved through the treatment course, with the greatest increases occurring between 6 weeks and 6 months. The mean range of motion at 6 weeks was 11.85 degrees +/- 0.824 degrees standard error, which had increased by 3.07 degrees +/- 0.862 degrees to 14.92 degrees (p < .0001) at 3 months postoperatively. From 3 to 6 months, it increased 3.96 degrees +/- 0.981 degrees to 18.88 degrees (p < .0001) at 6 months postoperatively. From 6 to 12 months, the mean range of motion increased to 20.11 degrees +/- 1.243 degrees (p = .3765). The overall mean increase in the range of motion from 6 weeks to 12 months was 8.25 degrees (p < .0001). These results have demonstrated a predictable incremental increase in motion over time, with the largest percentage of improvement occurring from 6 weeks to 6 months. This information will aid surgeons in guiding patient expectations after implant arthroplasty of the ankle. (C) 2011 by the American College of Foot and Ankle Surgeons. All rights reserved.
