Are Knock Knees Genetic?

Family members may share patterns of bone shape, joint alignment, growth, or movement control. That does not mean a child will have the same degree of knock knees or develop symptoms. Growth-related alignment, previous injury, bone or joint conditions, and nutritional or developmental factors can also be relevant. A clinician looks at the person’s age, growth pattern, symmetry, medical history, and examination findings rather than relying on family history alone. The appearance of knock knees is not a diagnosis of a specific inherited disorder.

Ask relatives whether similar alignment was present during childhood and whether anyone needed treatment, while remembering that family recollection is not a diagnosis. Keep a record of pain, limping, falls, activity limits, and changes in appearance. A clinician can examine the hips, knees, ankles, feet, walking pattern, and growth. Physiotherapy may help strength and coordination when those affect movement; Paediatric Physiotherapy offers child-focused support. Further tests are guided by examination findings.

Arrange review for one-sided or worsening alignment, persistent pain, limping, unusual short stature, repeated fractures, weakness, or difficulty keeping up with normal activity. Seek prompt advice for sudden deformity, severe pain, swelling, or inability to bear weight. A family history becomes more useful when several relatives have similar symptoms, early limitations, or known bone conditions.

Does the pattern look like a normal growth variation or something needing investigation? Does family history change the assessment? Are there signs of a bone or joint condition? Would physiotherapy help function? When would an osteotomy be considered?
