MPFL Reconstruction with Soft Tissue Femoral Fixation Technique in a Case of Congenital Patellar Dislocation with Long-term Follow-up: a Case Report.

Congenital patellar dislocation (CPD) is a rare condition in which the patella is laterally dislocated at birth. Surgical intervention is typically required due to abnormal knee development.This case report details a successful application of medial patellofemoral ligament reconstruction using a femoral soft-tissue fixation technique (ST-MPFL-R), combined with lateral release and vastus medialis advancement in a 7-year-old boy with CPD.ST-MPFL-R combined with lateral release and vastus medialis led to satisfactory results.This approach avoided damaging growth plates and achieved patellar stability at six-year follow-up. While the application of ST-MPFL-R for CPD was reported for the first time, further research with larger patient groups is needed to definitively compare it to traditional methods.
