OBJECTIVE
To evaluate the epidemiological and clinical characteristics of knee injuries in Brazilian Jiu-Jitsu (BJJ) practitioners.
METHODS
Cross-sectional study, using a mixed questionnaire, based on the Referred Morbidity Index.
RESULTS
198 amateur and professional BJJ fighters, of both sexes, aged between 18 and 60 years, participated in the study. The majority (88%) of the fighters had only one knee injury (p < 0.001). In total, 29.8% proportion of knee injuries (p < 0.001) was identified, which were mainly from the medial collateral ligament (38%), caused by a sprain mechanism (86%) and conservative treatment (65%).
CONCLUSION
A high prevalence of knee injuries in JJB fighters was found, compared to other sports that also perform rotational movements and have great body contact, such as mixed martial arts (MMA), judo, soccer, basketball and handball. Some JJB strikes, such as the key and the projection, can cause greater knee joint stress, both in the attacking fighter and in the opponent. The knowledge of the epidemiological characteristics of sports injuries is important in the elaboration of prevention and training protocols more specific to the sport and for the understanding of the complex mechanisms involved with this outcome in sport.
目的
评估巴西柔术（BJJ）练习者膝关节损伤的流行病学和临床特征。
方法
采用横断面研究，基于参考发病率指数使用混合问卷。
结果
198名年龄在18至60岁之间的男女业余和专业BJJ格斗者参与了该研究。大多数（88%）格斗者仅有一处膝关节损伤（p < 0.001）。总共确定了29.8%的膝关节损伤比例（p < 0.001），主要来自内侧副韧带（38%），由扭伤机制导致（86%），采用保守治疗（65%）。
结论
与其他也进行旋转动作且身体接触较多的运动相比，如综合格斗（MMA）、柔道、足球、篮球和手球，发现JJB格斗者膝关节损伤的患病率较高。一些JJB的招式，如绞技和抛投，在攻击方格斗者和对手身上都可能导致更大的膝关节压力。了解运动损伤的流行病学特征对于制定更具针对性的运动预防和训练方案以及理解与该运动结果相关的复杂机制很重要。
