Infrapatellar bursitis: symptoms and care

Repeated kneeling, pressure, friction, a knock or infection can irritate this bursa. A clinician can distinguish it from tendon, joint and skin problems by examining the exact location and movement of your symptoms.

The infrapatellar bursa sits between tissues at the front of the knee and helps them move with less rubbing. When inflamed, it may feel sore when kneeling or pressing the area, and a soft or firm lump may appear below the kneecap. The knee joint itself may still move fairly well. A history and physical examination are often enough to guide care; imaging or fluid testing may be considered when the diagnosis is uncertain or infection is a concern.

Reduce kneeling and direct pressure while the area settles. Use a cushion or knee protection for unavoidable tasks, and ask a clinician or pharmacist whether an anti-inflammatory medicine is suitable for you. Gentle movement can help prevent stiffness, but stop activities that sharply increase pain. If swelling persists, a clinician may discuss an injection or aspiration after checking for infection and other causes. Do not puncture or drain the swelling yourself.

Arrange medical review if swelling does not settle, keeps returning, limits walking or follows an injury. Seek urgent care if the area becomes hot and red, pain escalates quickly, pus appears, fever develops or you feel generally unwell. Infection in a bursa needs timely treatment and should not be managed by home drainage.

Ask whether the swelling is in the bursa or the knee joint, whether fluid testing is needed, which activities should be modified, and what signs would make an injection or aspiration unsafe or unnecessary.
