Considerations on recurrent patella dislocation in the adolescent athlete

Abstract

Recurrent patellar dislocation is described as loss of joint congruence between the femoral trochlea and the articular facet of the patella after a second episode. The etiology is multifactorial, including local, rotational and dynamic anatomical factors, and there is no clarity about its real influence, despite its high incidence and clinical importance. A search of Pubmed, Elsevier, Scielo, and Uptodate was conducted to identify recent articles on patellofemoral instability and recurrent patella dislocation. The pathogenic origin of recurrent patellar dislocation involves structural abnormalities, or muscle imbalances, its management is difficult, and multiple surgical techniques can be used. We recommend studying the possible causes and being consistent with them to carry out definitive treatment.
