Abstract

Intraarticular dislocation of the patella is an uncommon condition, with displacement in the horizontal or vertical plane, which may be associated with total or partial lesion/rupture of the quadriceps tendon, with osteochondral or collateral ligament injury. Risk factors are ligament laxity, patellar hypermobility, high patella, and trochlear dysplasia. This condition is more common in young people and may require blood reduction. Cases of intraarticular dislocation of the patella are rare events, requiring diagnostic suspicion and differentiated management. The aim of the present study is to report a rare case of intraarticular dislocation of the patella, as well as its clinical condition, diagnosis, management and literature review.
