Abstract

Patellar instability is a heterogeneous group of morphological and functional disorders of the knee extensor mechanism. The medial patellofemoral ligament (MPFL) has been recognized as being important in stabilizing the patella and preventing lateral patellar dislocation. Recurrent dislocations in the pediatric population may benefit from surgical intervention. The aim of this study is to retrospectively evaluate adolescent patients treated with surgical reconstruction of medial patello-femoral ligament. Between January 2009 and December 2014, seven patients with patellar instability were treated at the Department of Orthopaedics and Traumatology of the University of Catania, Sicily. Five patients (71.4%) were female and two (28.6%) were male. The mean age at the time of surgery was 14.9 ± 1.1 years (range 13–16 years). All cases were treated with reconstruction of the MPFL. Clinical outcomes and complications were reported. Mean follow-up was 26.1 ± 10.9 months (range 12–46 months). Evaluation at two years after surgery identified an average Knee Society Score (KSS) of 94.3 ± 7.4 (range 78–100). An excellent result was obtained in six patients (85.7%) and a good result was obtained in one patient (14.3%). A recurrence was reported in one patient (14.3%). This study shows that surgical treatment of patellar instability by reconstruction of MPFL leads to satisfying results at mid-term follow-up. View Full-Text
