Knock knees is when a child stands with their knees together and their ankles at least 2.5cm apart (intermalleolar distance). A gap of 6 – 7 cm between the ankles (intermalleolar distance) is normal between the ages of two and four years. Knock-knees usually resolve spontaneously approximately by the age of six years.
