How Is Knee Bursitis Treated?

A bursa is a small, fluid-filled cushion near the knee. Repeated kneeling, a knock, friction, arthritis or an infection can irritate it. A clinician checks where the swelling sits, whether the skin is hot or red, and whether movement is restricted. This helps distinguish bursitis from a deeper joint problem. Learn more about [Knee Bursitis](/conditions/knee-bursitis/) and related [Knee Pain](/symptoms/knee-pain/).

Early care may include avoiding kneeling and the activity that triggers symptoms, applying a wrapped cold pack, resting with the leg supported, and gradually restoring movement. A clinician may recommend anti-inflammatory medication when it is suitable for your health and other medicines; see [Anti-Inflammatory Medication](/treatments/non-surgical-orthopedics/anti-inflammatory-medication/). Physiotherapy can improve knee movement and strength without repeatedly loading the irritated bursa. If fluid needs assessment or relief, [Joint Aspiration](/treatments/non-surgical-orthopedics/joint-aspiration/) may be considered. Persistent, recurrent bursitis that does not respond to conservative care may rarely lead to discussion of [Bursa Removal](/treatments/reconstructive-orthopedic-surgery/bursa-removal/).

Arrange prompt medical assessment if swelling is rapidly worsening, the area is hot and red, pain is severe, you have fever, or the skin is broken near the swelling. These features can occur with an infected bursa and need timely treatment. Seek urgent help after a major injury, if you cannot bear weight, or if the foot becomes numb, cold or unusually pale.

Ask: Is the swelling in a bursa or inside the joint? Could infection be present? Which activities should I pause, and what movement is safe? Would aspiration or fluid testing help? When should I start physiotherapy, and what would make surgery worth discussing?
