In 1 year, 715 patients with soccer injuries were registered and treated in the emergency department of Randers City Hospital. We did a prospective study of these patients using a questionnaire to determine the most common locations, types, mechanisms, and treatments of injury. Financial costs for society and the individual were also examined. Forty-nine percent of the injuries were to the joints; sprains and contusions were the most common types of injury, accounting for 46% and 25%, respectively. The majority of patients (64% of the men and 58% of the women) were injured during physical contact with another player. Most (63%) of the patients were treated in the emergency department and then released. Thirty-one percent had to be absent from work, but only 8% of the patients had a loss of income because of their injury. The average amount of work time lost was 5 days.
