Abstract
Acute traumatic patellar dislocation is a common injury with majority of them occurring in young adults less than 20 years old. Traumatic patellar dislocation is mostly associated with trauma sustained during physical or sports activity. Strong patellar displacement leads to injury involving medial stabilizing structures, notably the medial patella-femoral ligament (MPFL), most frequently at its femoral attachment. Displacement involving more than 50% of the patellar width is considered abnormal. X-ray and computed tomography (CT) are helpful in diagnosing bony risk factors for patellar dislocation and to detect small osteochondral bodies. Magnetic resonance (MR) imaging is the primary diagnostic modality of choice and helpful in detecting capsular, ligamentous, cartilaginous, and bone injuries and thus can help in deciding the course of management. Here in we review the typical MRI imaging findings in the knee after acute traumatic patellar dislocation.
