Prepatellar Bursitis

The prepatellar bursa, also known as the “kneecap bursa,” is a small fluid-filled sac located just in front of the kneecap (patella) in the knee joint. Its purpose is to reduce friction and cushion the patella, which moves with the knee when it bends and extends. The prepatellar bursa acts as a protective layer, allowing smooth movement of the patella over the underlying tissues, such as muscles and tendons, as the knee joint flexes and extends.

Prepatellar bursitis is a condition characterized by inflammation of the prepatellar bursa. This condition is often referred to as “housemaid’s knee” or “carpet layer’s knee” because it can result from repeated or prolonged kneeling on hard surfaces, causing irritation and inflammation of the bursa.

Prepatellar bursitis is typically caused by repetitive trauma or excessive pressure on the kneecap area. Common causes include frequent kneeling, activities that involve pressure on the knee, or direct trauma to the bursa. In some cases, it can also be linked to infections.

Symptoms of prepatellar bursitis often include localized pain, swelling, redness, and warmth over the front of the knee. The affected area may be tender to the touch, and it can limit your ability to bend or extend the knee comfortably.

Diagnosis of prepatellar bursitis typically involves a combination of a comprehensive physical examination, x-rays, and possibly an MRI or ultrasound to confirm the diagnosis and rule out other conditions.

Prepatellar bursitis is an inflammation of the bursa in front of the kneecap, often caused by prolonged kneeling, direct trauma, or repetitive stress. Symptoms include swelling, tenderness, and restricted knee movement. Dr. Jorge Chahla offers both non-surgical and surgical treatments for prepatellar bursitis, helping patients relieve pain and restore normal function.
