ABSTRACT

The inability to achieve full knee extension of a child, is a deformity that can produce from very mild conditions, to the total impossibility for walking and standing. This extension lag may be due to inherent problems in the soft tissues, bone deformities or a superposition of both. The most common causes are arthrogryposis, rheumatoid arthritis, lower limb postaxial hypoplasia, cerebral palsy, and osteogenesis imperfecta. These deformities have traditionally been treated in adults and children with elongation surgeries and osteotomies, acute or progressive corrections and fixation with the use of external fixators or plates. The bone immaturity gives us the ability to direct the growth of the physics, providing another therapeutic option less invasive and more biological. Its progressive correction nature makes unnecessary performing a soft tissues elongation that usually accompany these deformities, and also avoid osteotomies and big scars. In this article we will present an overview of the history of growth modulation in the sagittal plane, its foundations, chronological evolution of the implants, considerations when selecting the implant and concepts in our experience will help the reader understand how to perform successful pediatric knee lack of extension correction.
