Pes Anserine Tendinobursitis Syndrome

(Goosefoot Bursitis; Pes Anserine Bursitis; Anserine Tendonitis)


Pes anserine tendinobursitis syndrome is pain on the inside of the knee just below the joint. It happens when three tendons at the inside of the knee become inflamed. This is called tendonitis. The thin sac (bursa) between the shinbone and the three tendons also becomes inflamed. This is called bursitis.

Tendons Meet and Connect to Bone.

The reason why this problem develops is not clear. Some causes are:

  • Overuse
  • Trauma

Risk Factors

This problem is more common in women. It is also more common in people who are 50 to 80 years of age.

Other things that may raise the risk of this problem are:

  • Some activities such as long-distance running, racquet sports, or basketball
  • Tight hamstrings


The main symptoms are pain and swelling on the inside of the knee just below the joint. The pain may be worse with activity, such as going up or down stairs. It may also be worse at night or first thing in the morning.


The doctor will ask about symptoms, past health, and physical activities. A physical exam will be done that will focus on the knee. This is often enough to make the diagnosis.


The goal of treatment is to ease pain and swelling. Choices are:

  • Supportive care, such as cold compresses and avoiding activities that cause pain
  • Physical therapy to help with strength, flexibility, and range of motion
  • Medicines to ease pain and swelling, such as:
    • Over the counter or prescription pain relievers
    • A steroid injection


The risk of this health problem may be lowered by slowly increasing the intensity and duration of activities.
