Angular Deformity Correction

What are Knee Angular Deformities?

Angular deformities of the knee are common during childhood and usually are variations in the normal growth pattern. Angular deformity of the knee is a part of normal growth and development during early childhood. Physiologic angular deformities vary with age as:

• During the first year: Lateral bowing of tibia
• During the second year: Bow legs (knees and tibia)
• Between 3-4 years: Knock knees

The condition usually becomes more evident when the child is 2 to 3 years old and normally corrects itself by the time a child is 7 or 8 years old. However, if the condition is not corrected, it could be a sign of an underlying problem that requires treatment.

Diagnosis of Angular Deformities

The diagnosis of bow legs or knock knees is made through a physical examination. In addition, X-rays may be taken if a child is older than 2 ½ years and has symmetrical legs.

Treatments for Angular Deformities

Treatment for Bow Legs

As the child grows, the condition usually corrects itself. For children with severe, unresolved bow legs, doctors may recommend non-surgical treatment options such as bracing, physical therapy and medications. If non-surgical treatment options do not correct your child’s bow legs, then surgery is considered.

Treatment for Knock Knees

Most children with knock knees do not require any treatment, but if the condition persists after age 7, then a night brace attached to an orthopaedic shoe may be recommended. If the separation between the ankles is severe, surgery may be an option.
