What about the other knee bursae?

A second bursa of the knee is located just under the kneecap beneath the large tendon that attaches the muscles in front of the thigh and the kneecap to the prominent bone in front of the lower leg. This bursa is called the infrapatellar bursa, and when inflamed, the condition is called infrapatellar bursitis. It is commonly seen with inflammation of the adjacent tendon as a result of a jumping injury, hence the name "jumper's knee." This condition is generally treated with ice, rest, and oral anti-inflammatory and/or pain medicines.

A third bursa of the knee is called the "anserine bursa." It is located on the lower inner side of the knee. This bursa most commonly becomes inflamed in middle-aged women. This condition is referred to as anserine bursitis. Anserine bursitis is particularly common in those who are obese. These patients can notice pain in the inner knee while climbing or descending stairs. Anserine bursitis is generally treated with ice, rest, and oral anti-inflammatory and/or pain medicines, although cortisone injections are also given.

What is the prognosis (outlook) of knee bursitis?

The outlook for knee bursitis is generally very good. Mild bursitis resolves spontaneously with rest. More significant bursitis can require medications (either taken by mouth or locally injected) to reduce inflammation. Infectious bursitis requires drainage, possibly surgical resection, and antibiotics.

Can knee bursitis be prevented?

To the extent that the bursitis is caused by injury or athletic activity, it can be prevented by avoiding reinjury to the bursa and adjacent tissues.
