Knee Bursitis Home A-Z Health Information Health Library A-Z Knee Bursitis Overview Knee bursitis is defined as inflammation of bursae, tiny fluid-filled sacs that minimise friction. It serves as a cushion between bones, tendons, muscles, and skin around joints, absorbing pressure and protecting the joints. This condition frequently affects the region above the kneecap or the inner region of the knee (beneath the joint); it limits knee movement and causes pain and discomfort. Causes Knee bursitis can result from prolonged pressure on the knees (e.g., kneeling), overuse of the knee joint, direct blows, bacterial infections, or medical conditions like osteoarthritis, rheumatoid arthritis, or gout. Risk factors Extended pressure on the knee from activities like prolonged kneeling (common in carpet layers and plumbers).Repetitive knee strain associated with specific sports (e.g., wrestling and football) or from direct impact.Underlying health conditions, including bacterial infections, osteoarthritis, rheumatoid arthritis, gout, or obesity.Preventive measures include wearing kneepads, taking breaks between intense physical activities, and maintaining a healthy body weight. Symptoms Symptoms differ depending on the bursa involved and the cause of inflammation. Common symptoms include warmth, soreness, swelling, and pain while moving or resting the knee.Sudden symptoms may occur after a direct hit.Kneeling on hard surfaces can cause chronic symptoms.Fever, bruising, swelling and skin changes near the knee, along with difficulties moving the knee, may also be observed. Diagnosis Reviewing medical history.Conducting physical examinations.Performing imaging tests (e.g., X-ray, MRI, and/or ultrasound) or fluid aspiration. Treatment Non-surgical treatmentNon-surgical options include medications, such as antibiotics for infections, and physical therapy. At-home care may involve rest, over-the-counter pain relievers, applying ice, compression, elevation, and, if necessary, weight management.Surgical treatmentIn some cases, corticosteroid injections or fluid drainage through aspiration may be recommended; this enables outpatient recovery. Surgery to remove the bursa is rarely needed. Following treatment, patients are advised to engage in basic or advanced physiotherapy. However, returning to normal activities should be discussed with an orthopaedic specialist for injury prevention (especially, reinjuries) and ensure a faster recovery.
