Skeletal problems, infection, and tumors can also affect
the growth
of the leg, sometimes giving
rise to a one-sided bow-leggedness. The remaining causes are occupational, especially among jockeys, and from physical trauma, the condition being very likely to supervene after accidents involving the condyles of the femur.
When the deformity arises in older patients, either from trauma or occupation, the only treatment is surgery.
Have you got any investigatins like X ray, MRI done?
Best.
