The knee joint is surrounded by three major bursae. At the tip of the knee, over the kneecap bone, is the prepatellar bursa. This bursa can become inflamed (prepatellar bursitis) from direct trauma to the front of the knee. This commonly occurs when maintaining a prolonged kneeling position. It has been referred to as “housemaid’s knee,” “roofer’s knee,” and “carpet layer’s knee,” based on the patient’s associated occupational histories.
Bursitis of the knee can occur when the bursa fills with blood from injury and overuse, such as from athletic competition. Bursitis can also occur from rheumatoid arthritis and from deposits of crystals, as seen in patients with gouty arthritis andpseudogout. The prepatellar bursa can also become infected with bacteria (septic bursitis). When this happens, fever may be present. This type of infection usually occurs from breaks in the overlying skin or puncture wounds. The bacteria involved in septic bursitis of the knee are usually those that normally cover the skin, calledStaphylococcus. Rarely, a chronically inflamed bursa can become infected by bacteria spreading through the blood.
Treatment for Knee Bursitis depends on whether it’s caused by infection. Here are the following treatment procedures:
o NSAIDs: These medicines decrease swelling, pain, and fever. NSAIDs are available without a doctor’s order. Ask your caregiver which medicine is right for you. Ask how much to take and when to take it. Take as directed. NSAIDs can cause stomach bleeding and kidney problems if not taken correctly.
o Antibiotics: These help fight an infection caused by bacteria. You may need antibiotics if your bursitis is caused by infection.
o Steroid injection: This shot will help decrease pain and swelling.
• Bursectomy: This is surgery to remove your bursa. Surgery is only done when other treatments do not work.
