Medial Patellofemoral Ligament and Associated Injury Patterns in Lateral Patella Dislocation: An MRI Study
نویسنده
چکیده
INTRODUCTION: Lateral Patella dislocations are common injuries seen in the active and young adult population [1]. The medial patellofemoral ligament (MPFL) has been identified as the major medial ligamentous restraint in preventing lateral patella subluxation and/or dislocation [2]. Ruptures of the MPFL can occur either at the femoral or the patella insertion site. However, it is commonly believed by orthopedic surgeons that rupture of the MPFL in acute lateral patella dislocations occur most often at the femoral insertion site [3]. Although this statement has some support in the literature based on operative findings, to our knowledge, there are few epidemiology studies evaluating injury patterns of the MPFL in patients with acute lateral patella dislocation. Our study aim is focused on evaluating the extent and location of injury to the MPFL and associated knee pathology using Magnetic Resonance Imaging studies in patients with the diagnosis of acute patella dislocation.

What Are Characteristic MRI Findings After Lateral Patellar Dislocation? Magnetic Resonance Imaging Characteristics of the Medial Patellofemoral Ligament Lesion in Acute Lateral Patellar Dislocations Considering Trochlear Dysplasia, Patella Alta, and Tibial Tuberosity–Trochlear Groove Distance
Background: There are a number of different factors that are thought to play a role in patellar instability, including injuries to the medial patellofemoral ligament (MPFL), trochlear dysplasia, patella alta, and an increased tibial tuberosity-trochlear groove (TT-TG) distance. Objective: To use MRI to assess injury patterns to the MPFL, trochlear dysplasia, patellar height, and TT-TG distance ...
متن کاملValgus instability as a cause for recurrent lateral patellar dislocation: a new mechanism for patellofemoral instability?
An association between lateral patellar dislocation (LPD) and medial collateral ligament injury (MCL) has recently been demonstrated on MRI. The same valgus injury that disrupts the femoral MCL insertion can also cause a simultaneous MPFL tear at its femoral insertion, due to the close anatomical relationship of both ligamentous structures. Valgus laxity due to MCL-deficiency increases the Q-an...

PURPOSE The purpose of this study was to determine the accuracy of MRI in determining both the extent and the location of injury to the medial patellofemoral ligament (MPFL). METHOD MR findings were compared to the surgical results of 14 consecutive patients who experienced transient patellar dislocation. Two musculoskeletal radiologists, blinded to the surgical results, retrospectively revie...
