The inflammation of a bursa, which is a small, fluid-filled sac at the knee joint, is known as Knee bursitis. The bursa helps in reducing the friction between the bones. The symptoms of this disease include swelling, warmth, tenderness, and redness in the knee area.
Anybody can get bursitis. It is more common among people who have jobs or hobbies that involve repetitive movement of a particular joint or groups of joints, or constant pressure on a particular area (e.g. playing lots of tennis or golf, sitting for long periods of time). The extrapolated prevalence is found to be 637,220 for two times of 19,913,144 population estimation used.
The Knee bursitis in initial stages can be treated by self-care and upon progression can be treated by anti-inflammatory and pain medications. The self-care includes usage of ice and rest. The medication involves aspirin, paracetamol or ibuprofen, corticosteroids and antibiotics. Occasionally, aspiration of the fluid is also required.
