A Clinical Journal of Sport Medicine study used the National Electronic Injury Surveillance System database and focused on tennis-related injuries treated in US emergency departments from 1990 to 2011. During this time, over 492,000 people aged 5 to 94 years went to emergency departments for tennis-related injuries. Most injuries were suffered during a nonspecific mechanism during play and occurred at a sport or recreation facility. Children aged 5 to 18 years had a higher injury rate than adults older than 19 years. The most commonly injured body part was the lower extremity. Sprains or strains were the most common type of injury.
The number of tennis-related injuries decreased by 41 percent, and the tennis-related injury rate decreased by more than 45percent during this time. Among the 3.4 percent of patients who were admitted to the hospital, two-thirds involved patients 56 years of age or older.
