Osteochondral Injury After Acute Patellar Dislocation in Children and Adolescents

Abstract

Level IV, diagnostic and therapeutic study.

Injury patterns of medial patellofemoral ligament and correlation analysis with articular cartilage lesions of the lateral femoral condyle after acute lateral patellar dislocation in children and adolescents: An MRI evaluation

“…Although the evaluation of MPFL tears after LPD in children and adolescents has been described in a few papers, there still remains some conflicts about the main rupture location of the MPFL [3][4][5][6][7][8][9]. Although there were some studies about articular cartilage lesions of the inferomedial patella and the lateral femoral condyle [4,5,[10][11][12][13][14][15][16][17][18][19][20][21], there were no studies concentrating on the correlations between the injury patterns of the MPFL and articular cartilage lesions of the lateral femoral condyle in children and adolescents. Therefore, we undertook this prospective magnetic resonance imaging (MRI) study to investigate the injury characteristics of the MPFL, as well as the correlations between the injury patterns of the MPFL and articular cartilage lesions of the lateral femoral condyle after acute LPD in children and adolescents.…”

Although the evaluation of MPFL tears after LPD in children and adolescents has been described in a few papers, there still remains some conflicts about the main rupture location of the MPFL [3][4][5][6][7][8][9].…”

ransient Patellar Dislocation Resulting in Simultaneous Osteochondral Fractures of Patella and Lateral Femoral Condyle – A Case Report

“…In majority of the studies, patellar osteochondral fracture is associated with a bony contusion involving the lateral femoral condyle in the classical impaction pattern of injury [1]. There are only two studies in which simultaneous osteochondral fractures of patella and lateral femoral condyle following patellar dislocation is reported in children and adolescents [2,3]. However, no case has been reported in the adult.…”

Open Reduction and Internal Fixation of an Osteochondral Patellar Fracture in an Eleven Year-Old Girl

“…Acute patellar dislocations (APD) are common in pediatric age and can be associated to osteochondral fractures (OCF) of the patella, the lateral femoral condyle, or both [1,2]. According to some works [1,3], the incidence of OCF is underestimated.…”

“…According to some works [1,3], the incidence of OCF is underestimated. In fact, osteochondral patella fractures can be easily missed on plain knee radiograms [1,4], making neglected OCF of the patella a possible reason for claims for financial compensation against attending doctors [5]. Although APD can occur even in the context of a stable knee, patient-related predisposing factors may contribute to dislocation [6,7].…”
