Osgood-Schlatter Disease: Causes, Symptoms, Treatment

Osgood-Schlatter disease, also known as jumper’s knee or growing pains, is a common condition that affects adolescents during their growth spurts. It causes pain in the knee and upper shin due to the pulling of tendons against the top of the shinbone.

In this article, we will explore the causes, symptoms, and treatment options for Osgood-Schlatter disease, providing helpful information for parents and teenagers alike.

What is Osgood-Schlatter disease?

Osgood-Schlatter disease occurs when the patellar tendon, which connects the muscles to the shinbone, pulls against the growth plate in the knee. This leads to pain and inflammation, often accompanied by a hard bump below the kneecap. Rest, over-the-counter pain medication, and time are usually sufficient to alleviate the symptoms of this condition.

How common is Osgood-Schlatter disease?

Osgood-Schlatter disease is the most common cause of knee pain in children and teenagers. It frequently affects individuals between the ages of 11 and 14 who are undergoing a growth spurt. It is more prevalent in adolescents who engage in sports that involve jumping or bending the knee, such as basketball or volleyball. In addition, those with tight quadriceps muscles are at a higher risk of developing this condition.

Understanding the patellar tendon

The patellar tendon is a band of tissue that connects the kneecap to the shinbone. It plays a crucial role in stabilizing the knee joint. During periods of rapid growth, the patellar tendon may exert excessive force on the growth plate, leading to pain and discomfort.

Causes and risk factors

Osgood-Schlatter disease is often associated with sports and activities that place repetitive stress on the patellar tendon. Running and jumping, in particular, can strain the leg muscles, causing the tendon to pull on the growth plate. Furthermore, the condition tends to arise during growth spurts when the bones, muscles, and tendons undergo significant changes.

Identifying the symptoms

The primary symptoms of Osgood-Schlatter disease include swelling, tenderness, and pain just below the kneecap. The pain may develop gradually or suddenly and can worsen with activities like running, jumping, or climbing. In addition, a hard, painful bump may form on the front of the knee, which is a result of new bone growth where the tendon pulls on the growth plate.

Diagnosis and treatment

Osgood-Schlatter disease is typically diagnosed based on symptoms and a physical examination. X-rays may be used to confirm the diagnosis and rule out other conditions like fractures. Most cases can be managed at home with rest, ice application, and over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief. It is essential to avoid activities that exacerbate the symptoms.

Stretching exercises that target the quadriceps can help release tension on the patellar tendon and provide relief. Some healthcare providers may recommend a patellar tendon strap, a brace worn around the knee, to reduce stress on the tendon.

Potential side effects and complications

While rare, long-term use of NSAIDs can lead to side effects such as heartburn, stomach pain, dizziness, and headaches. Stomach ulcers and high blood pressure are also possible, but they typically occur in individuals who use these medications for an extended period.

Complications from Osgood-Schlatter disease are uncommon. In severe cases, cortisone injections may be recommended to reduce swelling and alleviate pain. Surgery is a last resort and is only considered in rare cases when the pain persists for an extended period and significantly impairs daily activities.

Relieving symptoms and prevention

To alleviate the pain associated with Osgood-Schlatter disease, individuals can employ several strategies. Resting and avoiding activities that stress the knees, applying ice packs to reduce swelling, and taking NSAIDs as directed by a healthcare professional can provide relief. Regularly stretching the quadriceps muscles and attending physical therapy sessions, if recommended, can also be beneficial.

While it is not possible to prevent Osgood-Schlatter disease entirely, individuals can reduce the risk by participating in sports that do not stress the knees, taking breaks from activities when knee pain occurs, and engaging in regular stretching exercises to enhance flexibility and reduce pressure on the patellar tendon. Wearing supportive athletic shoes with good shock absorption is also advisable.

Most adolescents with Osgood-Schlatter disease recover fully without any lasting health effects. As the body continues to grow, the condition typically resolves. Although the bony growths may remain visible on the knees throughout adulthood, they are generally not painful.

When to seek medical attention

If your child experiences knee pain, especially after physical activity, it is important to consult a doctor. Seeking medical attention allows for an accurate diagnosis, ruling out other potential causes of pain and swelling.


Osgood-Schlatter disease is a common condition that causes knee pain in adolescents during their growth spurts. Understanding its causes, symptoms, and treatment options can help parents and teenagers effectively manage this condition.

By following the recommended self-care measures and seeking medical advice when necessary, individuals can alleviate the pain and discomfort associated with Osgood-Schlatter disease and continue to enjoy an active lifestyle.
