OBJECTIVES: Lateral ankle sprains (LAS) are among the most common injuries in professional football (soccer). Despite this, the severity and possible long-term consequences of LAS remain trivialised. This multicentre observational study in German elite football provides insights into time-loss and recurrence rates after LAS. Time-loss and recurrence rates are outcome measures vital for the future evaluation of rehabilitation protocols.
METHODS: 798 male football players representing 34 teams from 13 professional German football clubs participated in this study during the 2021-2022 season, followed by a 12-month follow-up period. Data collection and reporting were carried out in accordance with the UEFA recommendations for the standardised collection of data on football injuries. Time-loss, recurrence rate and standardised severity grades (I-III) after LAS were recorded for professionals, U23, U19 and U17, respectively.
RESULTS: A total of 187 ankle injuries were reported, with 115 out of the total being analysed. The overall time-loss was 29.89 days, with significant differences between youth elite players and professionals (32.96 vs 15.53 days lost; p<0.001). Professional players demonstrated the shortest time-loss in all LAS injury grades. Time-loss decreased with advancing age (R 2=0.03, F(1, 106)=3.16, p=0.078). Grade I LAS's time-loss differs significantly from grades II and III (p<0.001). A recurrent LAS was recorded in 34 players. The overall LAS recurrence rate was 25.6%.
CONCLUSION: This study provides data on time-loss and recurrence, which serve as reference values for future evaluation of rehabilitation concepts after LAS in elite football players.
