There was no significant change in the number of injuries between the years 2000 (n = 10,331; 95% CI, 7781-12,881) and 2017 (n = 9407; 95% CI, 7233-11,582) ( P = .64). Patients frequently sustained sprains, strains, or muscle tears (34.4%; 95% CI, 32.4%-36.5%) and fractures (24.8%; 95% CI, 23.1%-26.5%); these injuries most commonly affected the ankle (13.7%; 95% CI, 12.2%-15.2%) and the fingers of the hand (17.1%; 95% CI, 15.5%-18.7%). The greatest proportion of injuries occurred in male patients (60.7%; 95% CI, 58.7%-62.7%) who were 10 to 12 years of age (44.8%; 95% CI, 43.0%-46.6%), with over half of kickball-associated injuries occurring at school (54.1%; 95% CI, 50.7%-57.5%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Despite kickball\u2019s ubiquity as a schoolyard game, its associated injuries remain largely underappreciated.
