What Causes Knock Knees?

Video of the Day

Knock knees, also known by the technical name of genu valgum, is when the knees touch or angle inward, while the ankles do not touch and angle outward. Many toddlers have this condition, but it often corrects itself by the time they reach adolescence, states the Pediatric Orthopaedic Society of North America (POSNA).

Individuals with genu valgum have a more inward twist of their thigh bone (femur) and an outward twist of the shin bone (tibia), which gives the appearance of knock knees. This condition can be caused by an injury to the growth plate, or it can be a developmental issue.

Although knock knees occur often in toddlers, if it appears later in childhood, it could be a sign of rickets or osteomalacia. Also, note that children who have overweight or obesity are more likely to develop genu valgum or knock knees, as well as flat feet. The best thing you can do as a parent is to see a doctor for a thorough evaluation.

Treatment Options for Knock Knees

Young kids with knock knees usually don't require bracing, surgery or physical therapy as this condition often resolves on its own, says POSNA. For older kids and adults, it's important to talk with a doctor who can determine the best course of action.

Knock knees may cause muscle imbalances and knee pain because the kneecap or patella is not tracking correctly, says the Hospital for Special Surgery (HSS). It may also lead to ankle, hip and back pain due to alignment issues of the knee and ankle.


In some cases, knock knee surgery for adults is indicated to relieve the pain. HSS reports that young adults may require an osteotomy surgery to correct the alignment, while older adults may need knee replacement surgery.

Lifestyle changes, such as losing weight, may help reduce stress on the knees. To stay safe, avoid high-impact activities like running or jumping. With knock knee braces, adults and children may experience a reduction in pain.


Although exercise alone can't correct the angle of your bones, it may relieve your symptoms. Knock knees create muscle imbalances that can be corrected with specific exercises, notes the University of California San Francisco (UCSF),
