<unk> , commonly called "knock-knees", is a condition where the knees angle in and touch one another when the legs are straightened. Individuals with severe<unk>  deformities are typically unable to touch their feet together while simultaneously straightening the legs. The term originates from the Latin<unk> , "knee", and<unk> , "bowlegged".
Mild<unk>  is relatively common in children up to two years of age, and is often corrected naturally as children grow and develop. However, the condition may continue or worsen with age, particularly when it is the result of a disease, such as rickets or obesity.  Idiopathic is the term used to describe<unk>  that is congenital or has no known cause.
Other systemic conditions may be associated, such as Schnyder Central Corneal Dystrophy, an autosomal dominant condition frequently reported with hyperlipidemia.
