Ankle Sprains in Brazilian Professional Soccer: Epidemiological Analysis of 126,357 Match Hours

Objective  This study aimed to perform an epidemiological analysis of ankle sprains in professional soccer players in Brazil. Methods  This prospective epidemiological study analyzed ankle sprains in professional male soccer athletes during the Brazilian Championship and the Paulista Football Championship from 2016 to 2019. All on-pitch medical care provided in official matches was recorded. The variables evaluated included the age and position of the player, injury diagnosis, pitch site where the injury occurred, playing time, imaging tests performed, surgical treatment, time away from competitions, and injury recurrence. We assessed the incidence of injuries according to the Federation Internationale de Football Association (FIFA) incidence formula. Results  Ankle sprains represented 10.17% of total injuries, with a FIFA index equal to 2,002. Lateral ligament injuries represented 53.75% of all sprains. The forwards were the most injured athletes, with 86 lesions. The midfield had the highest number of sprains (75.50%). Almost half (47.04%) of sprains occurred in the final 15 minutes of each half-time. Injuries recurred in 31.22% of cases, and 7.11% of injuries underwent surgical treatment. The average time away from competitions was 13.95 days. Conclusions  Ankle sprains are common injuries in soccer. Although the average time to return to sport is brief, these injuries have a high recurrence rate and are potentially surgical, leading to a longer time off competitions.
