BACKGROUND: Although both gender- and sports-specific @entity130 exist among @entity2587 , gender differences in the types of @entity130 caused by sports activities, except for anterior cruciate ligament (ACL) injury and anterior knee @entity158 , are not well established. OBJECTIVE: An observational study with a retrospective case-series design was conducted to investigate gender-specific differences in the types of @entity130 sustained while engaging in sports activities common to both males and females. METHODS: We analyzed @entity130 sustained during sports activities including basketball, volleyball, tennis, skiing, track and field, and swimming, using data on age, sex, sports activities, activity levels, and @entity2587 that had been computerized at our sports medicine (orthopedics) clinic. Inclusion criteria were sports activities that had a record of >100 @entity130 in total and @entity2587 aged <50 years who were engaging in only 1 sports activity. We determined the absolute number of @entity1 in each category and their percentage (proportion) of our cohort. The proportions of common @entity130 caused by sports activities were investigated, and gender-specific differences in the types of common @entity130 caused by sports activities were clarified. The Fisher exact test was used to determine the significance (P < 0.01) of the gender-specific differences in the types of @entity2587 . RESULTS: According to our database, during the 14-year period between October 1992 and December 2006, a total of 2,989 @entity2587 (1,624 males and 1,365 females) aged <50 years who engaged in 1 of the 6 sports activities described consulted our sports medicine clinic. The most common @entity2587 were @entity130 (14.3%) and knee @entity158 (13.7%), followed by @entity3681 (9.4%), @entity1798 (7.0%), @entity130 (5.1%), @entity1642 (2.9%), @entity1643 (2.5%), @entity924 (2.1%), injury of the medial collateral ligament of the knee (2.0%), lumbar spondylolysis (1.7%), and @entity121 (1.5%). Among these 11 types of @entity2587 , a significantly higher proportion of females who engaged in basketball (24.4% vs 10.5%), volleyball (20.5% vs 4.5%), or skiing (41.4% vs 26.5%) presented with an @entity130 , compared with their male counterparts (all, P < 0.001). There was also a significantly higher proportion of females than of males among the track and field @entity2587 who presented with @entity1642 (18.7% vs 3.9%; P < 0.001). CONCLUSION: The findings of this retrospective study suggest that there are gender-specific differences in the types of @entity130 sustained during sports activities.
