Pes Anserine Bursitis/Tendinopathy: A Painful Knee Condition

Pes anserine bursitis, also known as pes anserine tendinopathy, is a painful condition that affects the inside of the knee. It occurs when the bursa (a small fluid-filled sac) and/or the tendons (three tendons that run along the inner lower aspect of the knee joint) become inflamed.

Causes and Symptoms

• Overuse or repetitive strain on the knee can lead to pes anserine bursitis.
• Pain and tenderness over the inner knee are common symptoms, often accompanied by local swelling.
• The condition can be triggered by activities such as running, jumping, or climbing stairs.
• In some cases, trauma or direct injury to the pes anserinus area can cause swelling of the bursa.

Key Points

• Pes anserine bursitis is a painful inflammation of the fluid-filled sac in the knee joint.
• Tendinitis is a condition characterized by inflammation of the tendons.
• Both conditions have similar symptoms and treatment options.
• The pes anserinus area is located two inches below the medial knee joint line, between the shinbone (tibia) and three tendons of the hamstring muscle.

Diagnosis

A diagnosis of pes anserine bursitis is made through a combination of:

• History of onset and symptoms
• Physical examination and clinical tests
• Applying pressure over the pes anserine bursa, which will be sore if it is inflamed

Common Signs and Symptoms of Pes Anserinus Tendinitis or Bursitis

Pes anserinus tendinitis or bursitis is a condition that affects the pes anserine bursa, which is located on the inner side of the knee. The symptoms of this condition can vary from person to person, but here are some common signs and symptoms:

• Pain and Tenderness: Pain and tenderness over the inner knee, particularly in the lower part, are common symptoms of pes anserinus tendinitis or bursitis [1][2].
• Local Swelling: The affected area may become swollen, which can be tender to the touch [3].
• Chronic Refractory Pain: People with this condition often experience chronic pain in the affected area that does not go away even after rest [4].
• Pain when Bending or Straightening the Knee: Bending or straightening the knee can cause pain and discomfort, especially if you have pes anserinus tendinitis or bursitis [5][6].
• Swelling around the Knee: Swelling around the knee joint is another common symptom of this condition [7].
• Pain when Touching the Inner, Lower Side of the Knee: Pain when touching the inner, lower side of the knee is a specific symptom that can indicate pes anserinus tendinitis or bursitis [8].

Other Symptoms

In addition to these symptoms, people with pes anserinus tendinitis or bursitis may also experience:

• Pain on the Inside of the Knee: Pain on the inside of the knee, particularly in the lower part, is a common symptom of this condition [9].
• Gradual Development of Pain: The pain associated with pes anserinus tendinitis or bursitis often develops gradually over time [10].

Diagnostic Tests for Pes Anserinus Tendinitis and Bursitis

Pes anserinus tendinitis and bursitis can be challenging to diagnose, but various diagnostic tests can help confirm the condition. Here are some of the common diagnostic tests used:

• Clinical Examination: A thorough clinical examination is essential in diagnosing pes anserinus tendinitis or bursitis. The doctor will examine the affected area, check for pain and swelling, and assess the range of motion in the knee joint.
• Imaging Tests: Imaging tests such as X-rays, Magnetic Resonance Imaging (MRI), and Computed Tomography (CT) scans can help confirm the diagnosis and rule out other conditions. MRI is considered the preferred imaging technique for diagnosing pes anserine bursitis [4][5].
• Physical Examination Tests: Physical examination tests such as applying pressure over the pes anserine bursa, resisting the action or stretching the three muscles that insert at the pes anserine, can also trigger symptoms and help confirm the diagnosis [13].

Other Diagnostic Considerations

It's essential to consider other conditions that may mimic the symptoms of pes anserinus tendinitis or bursitis. These include:

• Stress Fractures: Stress fractures of the proximal medial tibia may produce pain in the area of the pes anserine bursa [2].
• Panniculitis: Panniculitis of the underlying medial knee fat can also cause pain and swelling in the affected area.
• Extra-articular Cystic Lesions: Extra-articular cystic lesions such as synovial cyst, ganglionic cyst, parameniscal cyst, pigmented villonodular synovitis, and synovial sarcoma should be considered [3].

Diagnostic Accuracy

Diagnostic screening tests have been conducted to calculate sensitivity and specificity. The results show that a combination of clinical examination, imaging tests, and physical examination tests can help diagnose pes anserinus tendinitis or bursitis accurately.

Non-Surgical Drug Treatment Options

Pes anserinus tendinitis or bursitis can be effectively managed with non-surgical drug treatments, which aim to reduce inflammation and alleviate pain. The following are some commonly used medications:

• NSAIDs (Non-Steroidal Anti-Inflammatory Drugs): Ibuprofen is the drug of choice for patients with mild to moderate pain [5]. It inhibits inflammatory reactions and pain by decreasing prostaglandin synthesis.
• Corticosteroid Injection: An injection of cortisone, which is an anti-inflammatory steroid medication, may be given to relieve pain. Relief from a cortisone injection is usually highly effective, but the duration of relief varies [8].
• NSAIDs for Pain Management: NSAIDs can be used if required to help manage your pain. However, these aren't recommended for long-term use, as they can have adverse effects on the stomach and kidneys [9].

Important Considerations

It's essential to note that while drug treatments can provide relief from symptoms, they may not address the underlying cause of pes anserinus tendinitis or bursitis. In some cases, additional treatment modalities, such as local injection of a corticoid like methylprednisolone [13], may be indicated.

The differential diagnosis for pes anserine tendinitis or bursitis can be extensive and is crucial for accurate diagnosis and treatment [10]. The conditions can be categorized based on their likelihood and prevalence.

Some possible differential diagnoses include:

• Other causes of medial knee pain: Pes anserinus bursitis is often confused with other causes of medial knee pain, such as osteoarthritis, meniscal tears, or ligament sprains [11].
• Tendinopathy: Many patients with pes anserinus bursitis and tendinopathy start to feel better within a few weeks of the injury. However, if left untreated, tendinopathy can lead to chronic pain and disability.
• Bursitis: Bursitis is inflammation of the fluid-filled sacs (bursae) that cushion joints and reduce friction between bone and soft tissue. In the case of pes anserine bursitis, the bursa becomes inflamed and distended with repetitive microtrauma [2].
• Osteoarthritis: Pes anserinus bursitis is commonly associated with osteoarthritis and/or overweight females [3]. The condition can be exacerbated by valgus stress and tendon tightness.
• Other conditions: Other conditions that may be considered in the differential diagnosis of pes anserine tendinitis or bursitis include pes anserinus syndrome, pes anserinus tendino-bursitis (PATB), and snapping tendinitis of the semitendinosus tendon [7].

It's essential to note that early diagnosis and proper treatment can give you the best chances of healing from pes anserine bursitis. While this condition can be easily treated, it's crucial to work to avoid recurrence, as the pain of pes anserine bursitis can interfere with your ability to move normally and maintain your quality of life [14].
