Self-reported information helps predict knee injury risk in female soccer players

Two self-reported measures are significantly associated with risk of knee injury in adolescent female soccer players, according to a Danish study that could have implications for screening.

In 326 adolescent female soccer players who were uninjured at the start of a season, researchers from Copenhagen University Hospital in Denmark assessed self-reported history of knee injury and scores on the Knee Injury and Osteoarthritis Outcome Score (KOOS) function questionnaire.

During the season that followed, players who suffered knee injuries that resulted in a loss of participation time were significantly more likely to have reported a history of injury at baseline than those who did not miss time with a knee injury. Risk of time-loss injury was also significantly associated with low baseline scores (fewer than 80 points) on three KOOS subscales: activities of daily living, sport/recreational, and quality of life.

The findings, which were epublished in July by the Scandinavian Journal of Medicine & Science in Sports, suggest that such inexpensive, easily administered outcome measures could be used for preliminary screening in this patient population.
