 Osgood-Schlatter disease results from stress on the epiphyseal plate in the tibia, leading to excess bone growth and a painful lump at the knee.There are important clinical implications of the growth plate physiology.For example guided growth surgery, also known as temporary hemiepiphysiodesis is used to achieve correction or straightening of the bone deformities in a variety of pediatric orthopedic disorders such as Blount's disease, rickets, arthrogryposis multiplex congenita and osteochondrodysplasias among others.
