Pes Anserine (Knee Tendon) Bursitis

What is pes anserine bursitis?

There is a pocket-like structure in the inside, or medial, aspect of the lower knee that can get inflamed. It is called the pes anserine bursa. This is where three different tendons of the thigh attach below the knee. This pocket can get inflamed in a condition known as pes anserine bursitis or tendonitis. The condition often results from weak or tight tendons, leading to inflammation at their attachment.

What are the symptoms?

Pes anserine bursitis can lead to pain and sensitivity in the inner lower aspect of the knee. This region will be sensitive to the touch. The pain is often exacerbated by knee bending.

How is it diagnosed?

Diagnosis is generally made through a discussion with your doctor and thorough examination. X-rays are often used to rule out other conditions.

How is knee bursitis or tendonitis treated?

There are a variety of treatments. Your doctor might recommend physical therapy, a home stretching program, anti-inflammatories and icing. A cortisone injection to reduce inflammation may be recommended in more severe cases.
