Prepatellar bursitis

Prepatellar bursitis is a condition characterized by inflammation of the prepatellar bursa, a small fluid-filled sac located in front of the kneecap (patella).

The primary function of the bursa is to reduce friction and cushion pressure points between the bones and tendons or muscles around the knee joint.

When inflamed, it can cause swelling, pain, and tenderness in the front of the knee, often making activities such as kneeling or bending the knee uncomfortable or painful.

This condition is commonly caused by repetitive kneeling, direct trauma to the knee, or infections.

It is often seen in individuals who work in occupations that require frequent kneeling, such as carpet layers, plumbers, and gardeners, leading it to be colloquially known as "housemaid's knee.

" Diagnosis of prepatellar bursitis is typically clinical, based on physical examination and medical history, although imaging such as MRI or ultrasound can be used if the diagnosis is uncertain or if there is suspicion of other knee pathologies.

Treatment generally involves rest, ice application, compression, elevation (RICE), and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain.

In cases where infection is present, antibiotics may be prescribed, and occasionally, aspiration of the bursa fluid or surgical intervention may be necessary.
