How do you fix Blount’s disease?
Many different types of surgeries can correct Blount disease — some involve cutting the tibia, realigning it, and holding it in place with a plate and screws (this is called an osteotomy); some involve removing the damaged growth plate; and some use a device called an external fixator to hold the bones in place from …
