  • If your child can walk without causing the knee to dislocate, the doctor will ask him to walk around and to straighten and bend his knee.
  • Then, the doctor will feel around the kneecap area to make sure the bones and muscles feel normal.
  • X-rays may be needed to determine how well the kneecap can fit into the groove.
  • Occasionally, your doctor also may order an MRI to check for ligament tears in the knee.
