Abstract
Patellofemoral instability (PFI) is one of the most common knee pathologies in children and adolescents. The high risk of re-dislocation necessitates a targeted risk analysis. A high-riding patella and a changed pulling direction of the extensor apparatus, which can be determined from the TTTG distance, are the main risk factors of PFI, also in a young population. The indication for surgical treatment, which is increasingly based on evidence, does not differ significantly from that of adults. However, due to the risk of disturbance of the growth plates, tibial tubercle osteotomy cannot be performed with open physis, which means that the surgical techniques must be adapted to the circumstances. A correction of a high-riding patella and an increased TTTG distance is possible with distal soft tissue procedures without impairing the growth plates, even in children and adolescents, and leads to better results compared with isolated MPFL reconstructions if the cut-off values of risk factors are exceeded and the indication is correct.
