If you or your child has been diagnosed with femoral anteversion — or if you've spent years wondering why your hips look rotated, your knees tend to cave inward, or your gait simply feels off — you've probably encountered advice that ranges from "wait and see" to generic stretching or, in more severe cases, surgery.

Proximal focal femoral deficiency is one of the rarest and most structurally complex congenital limb conditions. Families navigating it, and adults managing it long-term, rarely receive information that goes deeper than surgical options and prosthetic timelines.

For many adults, discovering they have developmental dysplasia of the hip (DDH) comes as a quiet but life-altering shock. It usually starts as an occasional ache deep in the groin, a clicking sensation during a normal walk, or a feeling of instability when standing up.

Coxa valga is not something most people go looking for. Usually a doctor mentions it after an X-ray taken for something else — a limp that would not resolve, a hip that felt loose, a routine scan in a child with cerebral palsy or a connective tissue condition.
