Descriptive Epidemiology of Injuries Sustained in National Collegiate Athletic Association Men’s and Women’s Lacrosse, 2004–2005 Through 2013–2014 Seasons

Abstract

Background: Men’s and women’s lacrosse operate with significantly different rules, equipment, and contact. Previous studies have assessed injury rates (IRs) in either men’s or women’s lacrosse, but a few studies have compared injury patterns in the National Collegiate Athletic Association (NCAA) men’s and women’s lacrosse. Purpose: We sought to examine whether there were differences in injury type, mechanism, setting, and time loss in men and women playing lacrosse in the NCAA. Methods: We performed a retrospective case-control study using data collected by the NCAA Injury Surveillance Program (ISP) during a 10-season period (2004–2005 to 2013–2014). The data were assessed for potential differences in injuries between male and female lacrosse players and analyzed to obtain descriptive statistics through calculations of rates, percentages, and confidence intervals (CIs). Main outcomes measured were IRs per 1000 athletic exposures (AEs) and injury rate ratios (IRRs) with 95% CIs. Results: The IRs were 5.19 per 1000 AEs in women’s lacrosse and 6.52 per 1000 AEs in men’s lacrosse. Men had more injuries overall than women in competitions and practices and in preseason, regular season, and postseason play. Preseason IRs were higher than the regular season, and competition injuries were greater than practice injuries in both sexes. Women had more injuries to the head/face, knee, lower leg, and foot. Sprains, strains, concussions, and contusions were the most common types of injuries in both sexes. Overuse/gradual onset, cartilage, concussion, inflammation, and tendinosis injuries were more common in women than men. Injuries in men resulted in time loss more often than injuries in women. Conclusions: Our retrospective study’s findings suggest that there were differences in injury patterns between men’s and women’s lacrosse. Future prospective research should assess whether these disparities are due to differences in equipment and rules and whether changes to these factors can reduce injuries.
