Knock-Kneed Legs Treatment: Practical Options

Knock knees, or genu valgum, bring the knees closer together while the ankles remain apart. In a growing child, the appearance may be part of changing leg alignment. In an adult, symptoms may relate to altered loading, muscle control, an old injury, or joint changes. One-sided or progressively changing alignment deserves closer review.

An assessment may include standing alignment, walking, squatting, joint motion, muscle strength, foot position, and pain location. Imaging is considered when the alignment is marked, persistent, painful, or relevant to a surgical decision.

If there is no pain or functional problem, monitoring may be all that is needed, particularly during growth. When movement control contributes to symptoms, physiotherapy can address hip and thigh strength, balance, mobility, and activity technique. [Paediatric Physiotherapy](/treatments/physiotherapy-and-rehabilitation/paediatric-physiotherapy/) offers age-specific assessment for children.

Supportive footwear and sensible activity changes may improve comfort, but inserts or braces should be selected with professional advice. If fixed bone alignment causes ongoing symptoms or uneven joint loading, an orthopaedic surgeon may discuss [Osteotomy](/treatments/reconstructive-orthopedic-surgery/osteotomy/), a procedure that realigns bone.

Arrange care for persistent pain, limping, reduced endurance, difficulty with stairs, repeated falls, or alignment that is worsening or clearly different on one side. Seek urgent help after injury when the leg is visibly deformed, cannot bear weight, becomes rapidly swollen, or the joint is hot with fever.

Ask whether the alignment is flexible or fixed, whether both legs are affected, and what finding is driving the treatment recommendation. Ask which activities are safe, how progress will be measured, and when imaging or an orthopaedic referral is needed. For a child, ask how growth may change the plan.
