The most common reason your legs might not appear straight when you walk, especially if it's been this way since childhood, is due to a condition called physiologic genu varum, often referred to as bow legs.
Understanding Physiologic Genu Varum
This condition frequently develops because of the cramped position you were in while developing in your mother's uterus. Your bones had to rotate to fit in the limited space, leading to a bowed appearance in the legs.
Other Potential Causes of Non-Straight Legs
While physiologic genu varum is common, other factors can also contribute to non-straight legs, including:
-
Blount's Disease: This condition affects the growth plates around the knee and can cause bowing, particularly in children.
-
Rickets: A deficiency in vitamin D or calcium can lead to weakened bones and skeletal deformities, including bow legs or knock knees.
-
Bone Fractures or Injuries: Past injuries that didn't heal correctly can also cause leg misalignment.
-
Genetic Factors: Some individuals may have a genetic predisposition to develop bow legs or knock knees.
What to Do
If you're concerned about the alignment of your legs, it's best to consult a doctor or physical therapist. They can properly diagnose the cause and recommend appropriate treatment options if necessary. For most cases of physiologic genu varum, the condition resolves on its own as the child grows. However, in other cases, treatment might be needed.
