Distal Femoral Extension Osteotomy

Why is this surgery recommended?

  • Increase the ability of the knee to straighten (extend)
  • Improve walking pattern for children who walk with knees bent (crouch position).

What happens during the surgery?

Your child's surgeon will make a cut across the front of the thigh just above the knee. 

A wedge of bone is cut out of the thigh bone.

The leg is straightened and then a metal plate and screws are used to hold it in place.

This is often combined with a patellar plication.
