A pre-patellar bursa is a space between the tissues in front of the knee which is enclosed like an envelope and lined with lubricating cells.

There are several bursae around the knee. The pre-patellar bursa is just in front of the kneecap.


Function of the pre-patellar bursa

As the knee bends and straightens with ordinary activities, the bursae - being lubricated - allow the tissues to slide and accommodate the activity. When a bursa becomes inflamed, perhaps from impact or involvement in repeated movement, it may fill with fluid and become painful, and range of motion of the knee may be reduced.


Pain syndromes related to the patella

A syndrome is a collection of signs and symptoms that tend to occur together.
