Researchers think the first surgery you describe, called anatomic reconstruction, may be the best choice for athletes with chronic ankle sprains. In one study, this procedure had good or excellent results 88 percent of the time, versus 58 percent for tenodesis, the other type of surgery. More than tenodesis, anatomic reconstruction allows athletes to maintain their activity level. Years later, they wind up with better ankle movement and stability, and fewer degenerative changes. Talk with your doctor to see which method he prefers in your case.
