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.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>798 male football players representing 34 teams from 13 professional German football clubs participated in this study during the 2021\u20132022 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\u2013III) after LAS were recorded for professionals, U23, U19 and U17, respectively.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 187 ankle injuries were reported, with 115 out of the total being analysed. The overall time-loss was 29.89\u2009days, with significant differences between youth elite players and professionals (32.96 vs 15.53\u2009days lost; p&lt;0.001).
