Acute Patellar Dislocation in Children and Adolescents

Abstract

The long-term subjective and functional results after acute patellar dislocation are satisfactory in most patients. Initial operative repair of the medial structures combined with lateral release did not improve the long-term outcome, despite the very high rate of recurrent instability. A positive family history is a risk factor for recurrence and for contralateral patellofemoral instability. Routine repair of the torn medial stabilizing soft tissues is not advocated for the treatment of acute patellar dislocation in children and adolescents.

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

“…The MPFL injury occurred in up to 78.4-94% in children and adolescents after acute LPD [3,4,6,8]. Injury to the MPFL may reduce passive stability and predict subsequent instability with non-operative treatment, and these have led to an increase in initial management by operative repair or reconstruction of the MPFL [15,[30][31][32][33][34][35]. However, the main rupture location of the MPFL in the case of LPD in children and adolescents remains debatable.…”

“…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.…”

Medial Patellofemoral Ligament Reconstruction and Nonanatomic Stabilization Techniques in Skeletally Immature Patients

“…Then, the graft is fixed at the adductor tubercle with an interference screw. 31 Giordano et al 32 described a variation of this technique (►Fig. 4B).…”
