Prepatellar bursitis

Prepatellar bursitis, also known as housemaid's knee or knee bursitis, is a common condition that causes inflammation of the bursa sac located in front of the kneecap. The bursa is a small fluid-filled sac that acts as a cushion between the bone and surrounding soft tissues, helping to reduce friction and pressure. Prepatellar bursitis can cause pain, swelling, and discomfort in the knee joint, and can be caused by a variety of factors.

Causes

Prepatellar bursitis can be caused by a variety of factors, including:

• Trauma: Direct trauma to the knee, such as a fall or blow, can cause inflammation of the bursa sac.
• Overuse: Repetitive activities that involve kneeling or crawling, such as gardening or cleaning, can put pressure on the bursa sac, causing inflammation.
• Infection: In rare cases, prepatellar bursitis can be caused by a bacterial infection.
• Medical conditions: Certain medical conditions, such as gout or rheumatoid arthritis, can increase the risk of developing bursitis.
