Pes anserine bursitis

Pes Anserine Bursitis is a condition characterized by inflammation of the pes anserinus bursa, located between the shinbone (tibia) and three tendons of the hamstring muscle at the inner side of the knee. This condition can cause pain and tenderness in the inner knee area, particularly just below the joint. Pes anserine bursitis is often seen in athletes, especially runners and swimmers, but it can also affect individuals who are overweight or have osteoarthritis.

Causes

Pes anserine bursitis is primarily caused by repetitive stress or overuse of the knee, leading to inflammation of the bursa. Other contributing factors include:

• Incorrect or excessive exercise
• Tight hamstring muscles
• Obesity, which puts extra stress on the knee
• Osteoarthritis in the knee
• Medial meniscus tear
• Valgus knee deformity

Symptoms

The main symptom of pes anserine bursitis is pain on the inner side of the knee, which may extend down the inner side of the shin. Other symptoms include:

• Tenderness and swelling over the pes anserinus area
• Pain that worsens with activity or when climbing stairs
• Stiffness in the knee, especially in the morning

Diagnosis

Diagnosis of pes anserine bursitis typically involves a physical examination, during which a doctor will assess pain and tenderness in the inner knee area. Medical history is also considered. Imaging tests, such as MRI or ultrasound, may be used to rule out other conditions with similar symptoms, such as a medial meniscus tear.

Treatment

Treatment for pes anserine bursitis focuses on reducing inflammation and pain, as well as addressing any underlying causes or contributing factors. Treatment options include:

• Rest and avoiding activities that exacerbate symptoms
• Ice application to reduce swelling
• Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief
• Physical therapy exercises to stretch and strengthen the hamstring muscles
• Corticosteroid injections to reduce inflammation (in severe cases)

Prevention

Preventive measures for pes anserine bursitis include:

• Gradually increasing the intensity of exercise
• Maintaining a healthy weight
• Strengthening and stretching the leg muscles, particularly the hamstrings
• Wearing appropriate footwear for activities
