Bow Leg and Knock Knees

Specialised treatment for bow leg and knock knees

Both bow legs and knock knees are common in children as they grow and almost always correct by themselves.

When standing with their feet and ankles together, a child with bow legs will have knees that stay apart. With knock knees, when the knees are together, the ankles stay apart.

bow leg and knock knees frequently asked questions

The following symptoms should be checked by a GP or Paediatrician:

Knock knees or bow legs are severe

  • A limp or pain
  • Bow legs remaining after the age of three years
  • Knock knees worsening after the age of eight years
  • Only one leg is affected

Symmetric bow legs and knock knees usually just a normal part of development as a child grows.

Your child’s Doctor will examine the child. You may be referred to a specialist if

  • Your child has a limp or pain
  • Only one leg is affected
  • The knocked knees/bows are severe or getting worse
  •  If bow legs worsen after 3 years of age
  • If knock knees persist after 8 years of age

No treatment is required unless the case is severe.  Surgery is rarely required – sometimes Guided growth surgery is needed which entails inserting small plates and screws to provide gradual correction while the child grows.

Your records and your care: important information for patients

Doctors will cease consulting patients at Orthopaedics SA from 1 June 2026 and Orthopaedics SA will also be closing down permanently from this date. We want to make sure all of our patients understand what this means for their ongoing care and any medical records held by Orthopaedics SA.

What is happening to my records? Your records will transfer to your surgeon’s new practice on 1 June 2026, so they remain accessible to them as your treating doctor. If your surgeon is retiring, we will transfer your records to the new practice and surgeon they have nominated to continue your care.

What if I don’t want my records transferred? You have the right to opt out. To do so, please contact our rooms:

  1. on 8267 8267 during our business hours of 9.00 am to 5.00 pm (SA time), Monday to Friday; or
  2. by replying to this email: info@orthosa.com.au; or
  3. in person, at your usual Orthopaedics SA clinic,

on or before Friday, 1 May 2026 to discuss your options. We will need to verify your identity, before discussing your records with you. If we do not hear from you by that date, we will proceed with the transfer as described above. We encourage you to speak with your surgeon well ahead of this date, to obtain details of the new practice and how it will handle your personal information.

What if I have more questions? Please contact our clinic directly using the number you already have on file.
