Description
Summary:The occurrence of permanent patellar dislocation associated with severe osteoarthritis is considered rare and difficult to treat. Literature: The literature is quite controversial on the subject. The objective of the study is to report two rare cases of severe osteoarthritis with permanent dislocation of the patella that underwent total knee arthroplasty, in addition to a review of the literature on the subject and related surgical technique. Total knee arthroplasty with using the medial parapatellar approach associated with lateral release was a good surgical option in patients with permanent patellar dislocation associated with advanced osteoarthritis. A ocorrência de luxação permanente da patela associada a osteoartrite grave é considerada rara e de tratamento difícil. A literatura é bastante controversa sobre o assunto. O objetivo do trabalho é relatar dois raros casos de osteoartrite grave com luxação permanente da patela que foram submetidos a artroplastia total do joelho, além da técnica cirúrgica relacionada e de uma revisão da literatura. A artroplastia total do joelho com o acesso parapatelar medial associado a uma liberação lateral foi uma boa opção cirúrgica em pacientes com luxação permanente da patela associada a osteoartrite avançada.
