Final answer:
The first line of treatment for Blount's disease if the age is less than 3 is usually a conservative approach that involves the use of braces or orthotics. Surgery is typically reserved for older children or those with more severe forms of Blount's disease.
Step-by-step explanation:
The first line of treatment for Blount's disease if the age is less than 3 is usually a conservative approach that involves the use of braces or orthotics. The aim is to correct the alignment of the legs and promote normal growth.
Braces and orthotics can help to redistribute the weight and stress on the legs, allowing the bones to grow in a more normal alignment. This treatment approach is usually effective in younger children with mild to moderate Blount's disease.
In some cases, if the conservative approach is not effective or the condition is severe, surgery may be considered. However, surgery is typically reserved for older children or those with more severe forms of Blount's disease.
