What is Osgood Schlatter's Apophysitis?

Osgood-Schlatter Apophysitis is a condition that affects the area just below the kneecap, where the patellar tendon attaches to the shinbone (tibia). It occurs when the growth plate in this area becomes irritated and inflamed, leading to swelling, tenderness, and sometimes the development of a bony bump. This condition is most common in children and adolescents who are still growing.

What Causes Osgood Schlatter's Apophysitis?

Osgood-Schlatter Apophysitis is caused by repetitive stress and strain on the growth plate located at the top of the shinbone (tibia), just below the knee. During activities like running, jumping, or kneeling, the quadriceps muscle pulls on the patellar tendon, which then tugs on the growth plate. In children and adolescents, these growth plates are softer and more vulnerable to irritation than fully developed bone.

Common contributing factors include:

  • Sports or physical activities that involve repetitive jumping, sprinting, or kneeling, such as basketball, soccer, or gymnastics.
  • Rapid growth spurts, which can increase tension in the muscles and tendons.
  • Tight quadriceps or hamstring muscles, which add extra strain on the knee and shin area.

 

These factors can cause inflammation, pain, and the characteristic bump at the site of the growth plate.

Symptoms of Osgood Schlatter's Apophysitis

Osgood-Schlatter disease causes pain just below the knee, where the patellar tendon attaches to the shinbone. There may be a bump or swelling in this area, and it’s often tender to touch. The pain gets worse with activities like running, jumping, or squatting.

The knee can also feel stiff, and the muscles around it, especially the quadriceps, may become tight. While pain is more intense during activity, it tends to improve with rest. Symptoms can vary, with some people feeling only mild discomfort, while others experience more severe pain that limits movement.

What Can Be Done To Treat Symptoms?

Treating Osgood-Schlatter’s apophysitis focuses on addressing factors that can be modified, such as training routines, exercise programs, and muscle tightness. The primary goal is to relieve pain and teach effective self-management strategies for your child at home.
 
Each treatment plan is personalized based on a thorough lower limb assessment and your child’s specific symptoms. Common treatments may include:
  • Strengthening and stretching exercises for surrounding muscles
  • Footwear assessments to ensure shoes provide proper alignment and support
  • Footwear modifications to improve comfort and reduce strain
  • Guidance on warm-up and cool-down techniques to prevent further strain
  • Custom orthotics to address any alignment issues that may be contributing to knee pain

 

This approach is designed to manage symptoms and improve overall mobility while minimising future discomfort.
