Osgood–Schlatter Disease

Causes of Osgood-Schlatter Disease

Osgood-Schlatter disease is caused by repeated stress and strain on the knee, specifically at the tibial tuberosity where the patellar tendon connects to the shinbone. This stress typically comes from activities like running, jumping, or kneeling, leading to inflammation and irritation of the growth plate in that region. Adolescents are particularly vulnerable during rapid growth phases due to the continuous development of their bones and tendons.

Risk Factors of Osgood-Schlatter Disease 

The risk factors for Osgood-Schlatter disease include:

• Age: It is most common in adolescents between 10 and 15 years old, particularly during growth spurts.

• Sex: While it occurs more frequently in boys, active girls can also be affected.

• Physical Activity: Engaging in sports that involve running, jumping, or frequent kneeling raises the risk.

• Growth Spurts: Rapid periods of growth can lead to the onset of the condition.

• Tight Muscles: Tight quadriceps or hamstring muscles can add extra strain on the knee joint.

• Biomechanical Issues: Improper alignment or movement patterns can also play a role in developing the condition.

Signs and Symptoms of Osgood-Schlatter Disease

• Knee Pain: Sharp or dull ache below the knee during activities like running or jumping.

• Swelling: Possible swelling at the tibial tuberosity just below the knee.

• Tenderness: Sensitivity in the affected area.

• Pain During Activity: Discomfort that worsens with knee movements, especially extension, and improves with rest.

• Stiffness: Increased stiffness after prolonged sitting or in the morning.

• Lump: A noticeable bump at the tibial tuberosity that may become more prominent during growth spurts.
