A genu valgum is considered pathological as a condition past the age of 7. Prior to that age, children are physically maturing and developing. Pathological genu valgum is also known as knock-knee and is seen when the knee, femur and tibia angle inward noticeably. Treatment is possible at younger ages due to the pliability of tissues in youth.
- Knock-knee is asymmetric and occurs in only one limb
- Excessive femoral anteversion
- Rotation of the tibia
- Unbalanced gait
There are different forms and causes for genu valgum including: metabolic bone diseases. skeletal dysplasias and physical trauma. To diagnose genu valgum, a clinician will perform a physical examination and order imaging studies to examine the degree of severity and physical causation of genu valgum.
In young children with developmental genu valgum, the condition should be self-correcting. In adult cases, surgical treatment is common in order to reform the physical structure of the limb.
