What is it?

Prepatellar (kneecap) bursitis refers to swelling of the front of the knee due to inflammation of the bursa, which is a fluid filled sac. It occurs due to irritation, damage or infection of the bursa. Actions that increase the risk for prepatellar bursitis include frequent kneeling, a direct hit to the knee, bacterial infection or having rheumatoid arthritis or gout. When the bursa is inflamed, there is an accumulation of fluids, causing it to get swollen and put pressure on the knee.
