Pes Anserine Bursitis


Pes Anserine Bursitis is a condition that results in significant knee pain. It’s a common issue, impacting thousands of Australians each year. Despite often being mistaken for typical knee arthritis due to similar symptoms, Pes Anserine Bursitis has distinct characteristics.

The condition involves inflammation of the bursa, a small fluid-filled sac, located between the shinbone and the three tendons of the hamstring muscle on the inner side of the knee. This inflammation can lead to discomfort and often affects mobility.

Pes Anserine Bursitis, a common cause of medial knee pain, often surfaces due to repetitive overuse or strain of the hamstring muscles. This tendon bursitis primarily affects athletes engaged in high-impact sports and individuals suffering from conditions such as knee arthritis.

The condition can also be triggered by meniscal cysts or even obesity, leading to an overburdening of the knee joint.

Symptoms are typically noticeable and distressing for those afflicted. Initial indications include sharp or dull shinbone pain that might worsen with certain activities like climbing stairs and stiffness near the inner part of your knee, which intensifies at night, causing sleep disturbances.

Some patients may notice a palpable mass corresponding to an inflamed bursa beneath their skin — this is another warning sign not to ignore. Over time you might experience weakness in your leg or find yourself dealing with a locking knee – further affecting mobility.

Moreover, inflammation can escalate into visible swelling around the area, adding another layer to discomfort levels.

Diagnosis and Treatment of Pes Anserine Bursitis

  • Diagnosis Process
    • Your healthcare provider will take a detailed medical history and physical examination.
    • They may ask about your symptoms, such as knee pain, swelling, sleep disturbance, weakness, and stiffness.
    • During the physical exam, they will check for specific signs like medial or anterior knee pain and palpable mass in the area.
    • In some cases, imaging tests like X-rays or MRI scans may be ordered to rule out other conditions and confirm the diagnosis. These tests can help identify any underlying issues such as meniscal cysts or knee arthritis, contributing to your symptoms.
  • Treatment Options
    • Once diagnosed with pes anserine bursitis, treatment options are available to alleviate your discomfort.
    • Initially, non-surgical approaches are typically recommended. Resting the affected knee is essential to reduce inflammation and promote healing.
    • Applying ice packs several times daily can help reduce swelling, while compression with a bandage provides additional support.
    • Your doctor may prescribe nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and decrease inflammation in the bursa.
    • Physical therapy exercises specifically designed for pes anserine bursitis can aid in reducing symptoms and improving mobility.
  • Surgical Intervention
    • If conservative measures fail to provide relief after several weeks or if there are persistent issues like locking knees or severe pain that interfere with daily activities despite nonsurgical treatments, surgical intervention might be considered as a last resort option.
  • Consultation
    • Remember that each case of pes anserine bursitis is unique; therefore, it’s important to consult with your healthcare professional for proper diagnosis and individualised treatment recommendations tailored to you.

Pes Anserine Bursitis is a painful condition that affects the knee. It is caused by inflammation of the bursa, usually due to overuse or injury. The symptoms include knee pain, swelling, and stiffness.

Diagnosis involves physical examination and imaging tests such as MRI or ultrasound. Treatment options include rest, ice, compression, and elevation (RICE therapy), anti-inflammatory medications like NSAIDs, and physical therapy for rehabilitation and strengthening exercises of affected muscles.

Seeking medical attention promptly can help in managing this condition effectively.


1. What causes pes anserine bursitis?

Pes anserine bursitis is commonly caused by overuse or repetitive stress on the knee joint, such as excessive running or jumping. It can also result from obesity, improper biomechanics, or trauma to the area.

2. What are the symptoms of pes anserine bursitis?

Common symptoms of pes anserine bursitis include pain and tenderness on the inside of the knee, especially when climbing stairs or after prolonged activity. Swelling and warmth in the affected area may also occur.

3. How is pes anserine bursitis diagnosed?

A medical professional will typically diagnose pes anserine bursitis through a physical examination and evaluation of your medical history. They may also order imaging tests like X-rays or MRI scans to rule out other possible causes for your knee pain.

4. What are the treatment options for pes anserine bursitis?

Treatment for pes anserine bursitis usually involves a combination of rest, ice therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy exercises to strengthen muscles around the knee joint. In severe cases, corticosteroid injections or surgical intervention may be necessary

5. Can pes anserine bursitis lead to complications?

Pes anserine bursitis, if left untreated, can lead to chronic pain and limited mobility in the knee. It can also increase the risk of recurring knee injuries. Therefore, it’s important to seek medical attention if you’re experiencing persistent knee pain.

6. Does age affect the risk of developing pes anserine bursitis?

Yes, age can be a factor. Pes anserine bursitis is more common in adults over the age of 50, primarily because the risk of conditions that can lead to bursitis, such as osteoarthritis, increases with age.

7. Can pes anserine bursitis be prevented?

While not all cases of pes anserine bursitis can be prevented, maintaining a healthy weight, exercising regularly to keep your knee muscles strong, and avoiding activities that put excessive stress on your knees can help reduce your risk.

8. How long does it take to recover from pes anserine bursitis?

The recovery time for pes anserine bursitis can vary depending on the severity of the condition and the effectiveness of the treatment. With proper treatment, most people see improvement in their symptoms within a few weeks. However, it’s important to continue with the recommended physical therapy exercises even after the pain subsides to prevent recurrence.
