Medial Patellofemoral Ligament and Associated Injury Patterns in Lateral Patella Dislocation: An MRI Study
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 belie...
متن کاملMedial patellofemoral ligament injury patterns and associated pathology in lateral patella dislocation: an MRI study
BACKGROUND Lateral Patella dislocations are common injuries seen in the active and young adult populations. Our study focus was to evaluate medial patellofemoral ligament (MPFL) injury patterns and associated knee pathology using Magnetic Resonance Imaging studies. METHODS MRI studies taken at one imaging site between January, 2007 to January, 2008 with the final diagnosis of patella dislocat...
متن کاملWhat 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 کاملPeriosteal Sleeve Avulsion Fracture of the Quadriceps Tendon
A 15-year-old girl presented with a primary lateral patella dislocationof her left knee after she slippedoff a starting block and struck the medial aspect of her knee. No reduction was required, the patellar dislocation spontaneously reducedwith gentle knee extension prior to evaluation. Patellofemoral anatomy measurements demonstrated an Insall–Salvati ratio of 1.5, a Caton–Deschamps index of ...
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...
