%X OBJECTIVE: Describe the ligamentous and associated injuries that occur in the traumatic knee dislocation, relating them to the mechanisms of trauma and to identify patterns of injuries. METHODS: Twenty three knee dislocations were described in the period between March 2010 and March 2011. After the diagnosis of the lesions, the reduction and transarticular external fixation of the dislocated knees were done. At the second moment, the patients were evaluated with physical examination under anesthesia and the surgical exploration of peripheral lesions was perfomed by a surgeon of the knee surgery group of this institution.The patients data with the description of the injuries were found and registered. RESULTS: 65% of patients were male, the average age was 35 years and the most common mechanism of trauma was the motorcycle accident (60%). The lesion of the anterior cruciate ligament (ACL) occurred in 75% of the cases, and the lesion of posterior cruciate ligament (PCL) in 95%. The medial peripheral injuries happened in 65% of the dislocations, and the lateral lesions in 40%. The most common dislocations were classified as KDI (25%) and as KDIIIm (25%). The arterial injury was present in 15% of the cases, and the nervous injury where registered in one patient (5%). At the initial radiographic evaluation, 45% of the dislocations presented reduced. CONCLUSION: The characteristics of the knee dislocations described showed a great range of variability demonstrating that an individualized evaluation of each case is mandatory. The surgeon should be able to recognize and choose the correct treatment to these lesions. OBJETIVO: Descrever as les es ligamentares e associadas ocorridas nas luxa  es traum¨˘ticas do joelho, relacion¨˘-las aos mecanismos de trauma e identificar padr es de les es. M¨¦TODOS: Foram descritas 23 luxa  es do joelho entre mar o de 2010 e mar o de 2011. Ap¨®s o diagn¨®stico das les es, foi procedida a redu  o e fixa  o externa transarticular das luxa  es. Num segundo tempo, os pacientes foram avaliados sob anestesia e a explora  o cir¨˛rgica das les es perif¨¦ricas foi feita pelos membros do grupo de cirurgia do joelho da institui  o. Os dados dos pacientes, junto com as descri  es das les es encontradas, foram registrados. RESULTADOS: 65% dos pacientes eram do sexo masculino, a m¨¦dia de idade foi de 35 anos, o mecanismo de trauma mais comum foi o acidente com motocicleta (60%). A les o do ligamento cruzado anterior (LCA) ocorreu em 75% dos casos, a les o do ligamento cruzado posterior (LCP) em 95%. A les o perif¨¦rica medial aconteceu em 65% das lux
