Sprains were classified into 4 degrees (I, II, IIIA, and IIIB). The same rehabilitation protocol was prescribed for all the athletes. The rate of a lateral ankle reinjury was recorded in the 24 months following injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At a follow-up of 24 months, 36 of 202 athletes (17.8%) experienced a second lateral ankle sprain.

Of the 81 athletes with a grade II injury, 23 (29%) experienced a recurrence during the study period. Of the 36 athletes with a grade IIIA injury, 2 (5.6%) experienced a recurrence during the study period.
