I am bow legged. What can I do to fix it?

Depends. If you are bowlegged, the problem could be in your thighbones (femurs), the bones in you leg (the tibia and fibula) or it could be that your knee ligaments could be relatively loose on the outside portion. Further, you could have any combination of these problems. If this is bothering you, you should see an orthopaedic surgeon, particularly one who specializes in limb deformity correction.
