The first episode of patellar dislocation has a multi-factorial etiology. Presently the various causes related to this event are well identified. However, the main cause of recurrent dislocation has not been determined. The objective of this work is to categorize the importance of each of these factors and was conducted reviewing relevant literature and describing and clearly identifying clinical and diagnostic findings. As incidence is low for this condition, we sought inter-institutional collaboration for this work which may significantly impact therapeutic alternatives to address the first trauma episode.
