Transient Lateral Sublaxation of Patella :Typical MRI (3T) Findings

Abstract

ABSTRACT: Lateral patellofemoral subluxation is an entity which often goes unrecognized clinically due to its transient nature. Patient usually complains of medial knee pain and is unaware of brief phase of dislocation of patella (as it gets reduced spontaneously). Recurrent dislocation may lead to osteochondral injury and osteoarthritis. MRI helps in specific diagnosis of this condition. We are presenting a case with telltale MRI signs of transient patellar dislocation.
