Resumo

A instabilidade patelar é uma condição clínica multifatorial, que acomete um número expressivo de pacientes, ocorrendo devido a variações anatômicas, morfológicas da articulação e do alinhamento patelofemoral. O presente estudo de revisão e atualização da literatura teve como objetivos identificar e sumarizar os conceitos atuais sobre instabilidade patelar em relação aos fatores de risco associados, os critérios diagnósticos e os benefícios e riscos dos tratamentos conservador e cirúrgico. Para tanto, foi realizado um levantamento nas bases de dados eletrônicas MEDLINE (via Pubmed), LILACS e Cochrane Library. Conclui-se que o diagnóstico preciso depende da avaliação clínica detalhada, incluindo o histórico e possíveis fatores de risco individuais, além de exames de imagem. O tratamento inicial da instabilidade patelar é ainda controverso, e requer a combinação de intervenções conservadoras e cirúrgicas, levando em consideração tanto os tecidos moles quanto as estruturas ósseas, sendo estas últimas a razão mais comum para a escolha do tratamento cirúrgico, principalmente instabilidade patelar lateral.

Palavras-chave
