A study conducted by Korean investigators finds no significant differences in clinical and radiographic results between patients undergoing total ankle arthroplasty for primary osteoarthritis compared with post-traumatic osteoarthritis
Long-Bin Bai, MD, and colleagues assessed 37 patients with post-traumatic osteoarthritis (OA) and 28 patients with primary OA who underwent total ankle arthroplasty. All of the patients had symptomatic ankle OA preoperatively and received the Hintegra (Newdeal) prosthesis. The patients were followed for a mean of 38 months.
At final follow-up, the investigators found that the groups had similar AOFAS ankle-hindfoot scale scores, range of motion and radiographic outcomes. However, they discovered a significantly higher rate of additional procedures in the post-traumatic OA group compared with the primary OA group (54% vs. 27%). The comparison also revealed a higher complication rate in the post-traumatic group (38% vs. 27%).
“The clinical and radiographic outcomes of total ankle arthroplasty for post-traumatic and primary osteoarthritis were comparable, although the incidence of complications after total ankle arthroplasty was higher in the post-traumatic osteoarthritis group,” the authors wrote in their study. “More preceding or concomitant surgeries were required in order to make the posttraumatic cases suitable for total ankle arthroplasty.”
