Children are prone to a selection of painful growth related lower limb conditions, commonly referred to as ‘growing pains’ and one of these is Sinding-Larsen Johansson Syndrome. Sinding-Larsen Johansson syndrome shows up as knee pain in children and is one of the paediatric podiatry conditions our Brisbane and Mount Isa podiatrists are trained to identify and treat.
Between the ages of about 10-14 years old, children can develop a specific type of knee pain called Sinding-Larsen Johansson syndrome. The condition occurs during these ages because 10-14 years is the typical range at which the patella (kneecap) and tibial (shin) growth plates are rapidly developing.
While the growth plates of the patella bone are developing, the patella bone is prone to injury from excessive force from the patella tendon pulling on the growth plate. This can happen due to a rapid growth spurt or high activity levels e.g. playing school sports.
If your child has Sinding-Larsen Johansson Syndrome, they will experience pain on their kneecap, where it connects into the patella tendon right at the bottom of the knee cap. Symptoms commonly include:
Pain Triggers
A number of conditions may be co-occurring with Sinding-Larsen Johansson Syndrome, such as Osgood Schlatter’s Syndrome, Sever’s disease, and hypermobility. It is best to get the exact problem diagnosed and treated by an Advance Foot Clinic podiatrist.
Sinding-Larsen Johansson Syndrome is primarily caused by age-related change to the bony growth plates, however a combination of factors can also contribute. The main contributing factors include:
Increased activity levels: Active children who regularly play multiple sports are much more likely to experience Sinding-Larsen Johansson Syndrome due to the increased stress on the patella tendon.
Genetics: We find that growth-related conditions tend to run in families. If an older sibling experienced Sinding-Larsen Johansson Syndrome or a similar condition (e.g. Sever’s disease), it is much more likely to occur in the family.
Foot structure and mechanics: Conditions such as overpronation (where the feet roll inward), genu valgum (knock knees), and hypermobility can all predispose a child to Sinding-Larsen Johansson Syndrome.
Inadequate footwear: Footwear without adequate arch support, cushioning, or stability can exacerbate symptoms and make your child more likely to experience Sinding-Larsen Johansson Syndrome or other growing pains. Footy boots, basketball shoes, ballet flats and other flat unsupportive shoes can worsen symptoms.
Your child’s medical history and a physical exam of their lower limbs including their knee will help diagnose Sinding-Larsen Johansson Syndrome. The main methods for treating the condition are:
