Common types of bursitis

Most cases of bursitis are of the non-infected type, and resolve on their own. The most common bursitis in the knee is pre-patellar bursitis, often seen in someone who has done uncommon exercise while kneeling, such as scrubbing a floor or fitting floor tiles. If there is any penetration of the bursa then it may become infected. Pes anserine bursitis may ocur in breaststroke swimmers.
