Causes and Symptoms of Sinding-Larsen-Johansson Disease

Sinding-Larsen-Johansson DiseaseSinding-Larsen-Johansson (SLJ) Disease is an overuse injury of the knee commonly seen in growing, active adolescents between the ages of 11 and 15 years. It is often referred to as Jumper's Knee and coincides with growth spurts.

Sinding-Larsen-Johansson causes pain and swelling at the lower end of the kneecap where the patellar tendon originates, caused by the increased tension and pressure applied to the kneecap during activities like running and jumping. The repetitive stresses of these activities can produce increased inflammation where the tendon attaches to bone. Tight quadriceps muscles, most common during a growth spurt, can also place increased pressure on the patellar attachment.

Treatment Options for Sinding-Larsen-Johansson Disease

While there is no 100% guarantee to prevent an active adolescent athlete from developing Sinding-Larsen and Johansson Disease, warming up and stretching before and after an activity may help to prevent the development of this painful condition.

For patients who develop Sinding-Larsen-Johansson disease, treatment options include:

  • Anti-inflammatory medication (as directed by the doctor)
  • Application of ice to the affected knee
  • Quadriceps and hamstring strengthening exercises and stretches to loosen tight muscles
  • Wearing a knee strap to decrease the amount of tension on the patellar tendon
  • Rest and activity modifications

By using a combination of conservative treatments, pain and discomfort in the affected knee will generally resolve over time.
