Increasing Emergency Department Burden of Brazilian Jiu-Jitsu Injuries: A National 10-Year Analysis of Mechanisms and Severity Predictors, 2015-2024

Background

Brazilian jiu-jitsu (BJJ) is a rapidly growing grappling-based combat sport, but emergency department (ED) surveillance and sport-specific mechanism classification are limited. Hypothesis: We hypothesized that BJJ-related ED visits have grown disproportionately compared with overall martial arts ED presentations and that sport-specific mechanisms predict nonroutine disposition. Study Design: Descriptive epidemiology study.
