Knee Bursitis: Causes, Symptoms and Treatment

knee bursitis symptoms

What Is Bursitis?

Bursitis is the inflammation or inflammation of the bursa. The bursa is a sac filled with lubricating fluid, situated between tissues such as bone, muscle, tendons, and skin, that reduces rubbing, friction, and irritation.

  • A bursa is a fluid-filled sac that works as a sliding surface to decrease friction between moving tissuesof the body.
  • There are three significant bursae of the knee.
  • Bursitis is generally not contagious, but the bursa can end up being infected.
  • Treatment of noninfectious bursitis includes rest, ice, and medications for inflammation and pain. Transmittable bursitis is treated with antibiotics, goal, and surgery.

What causes bursitis?

Bursitis is usually caused by repetitive, small impact on the area, or from an unexpected, more major injury. Age also plays a role. As tendons age they are able to tolerate stress less, are less flexible, and are much easier to tear.

Overuse or injury to the joint at work or play can also enhance a person’s risk of bursitis. Examples of high-risk activities consist of gardening, raking, woodworking, shoveling, painting, scrubbing, tennis, golf, skiing, throwing, and pitching. Incorrect posture at work or home and bad extending or conditioning before exercise can also result in bursitis.

What are causes of knee bursitis?

Bursitis of the knee can happen when the bursa fills with blood from injury and overuse, such as from athletic competition. Bursitis can also happen from rheumatoid arthritis and from deposits of crystals, as seen in patients with gouty arthritis and pseudogout. The prepatellar bursa can likewise end up being infected with bacteria (septic bursitis). When this occurs, fever might be present. This type of infection usually occurs from breaks in the overlying skin or puncture wounds. The bacterium involved in septic bursitis of the knee is typically Staphylococcus, which is usually present on the skin. Hardly ever, a chronically irritated bursa can become infected by bacteria spreading out through the blood.

Symptoms and signs

Bursitis can cause differing degrees of swelling, warmth, inflammation, and redness in the overlying area of the knee. As compared with knee joint swelling (arthritis), it is typically just mildly painful. It is regularly associated with increased pain up to severe when kneeling and can cause tightness and pain with walking. Likewise, in contrast to problems within the knee joint, the range of movement of the knee is frequently protected.

Knee bursitis and severe pain

Bursitis of the knee is detected based upon the normal location of a bursa displaying signs of inflammation consisting of severe knee pain, tenderness, tightness, and often redness and heat. Generally, there is point tenderness at the site of the swollen bursa.

Treatment for knee bursitis

The treatment of any bursitis dependson whether or not it includes infection. Aseptic prepatellar bursitis can be treated with ice compresses, rest, and anti-inflammatory and pain medications. Occasionally, it needs aspiration of the bursa fluid. This treatment includes removal of the fluid with a needle and syringe under sterile conditions and can be performed in the doctor’s workplace. In some cases the fluid is sent to the lab for further analysis. Noninfectious knee bursitis can also be treated with an injection of cortisone medication into the swollen bursa. Cortisone injections are in some cases done at the same time as the aspiration treatment.

Septic bursitis requires even greatly assessment and treatment. The bursal fluid can be examined in the lab to recognize the microbes causing the infection. It needs antibiotic therapy, typically intravenously. Repetitive aspiration of the swollen fluid may be required. Surgical drain and removal of the infected bursa sac (bursectomy) might also be needed.


The outlook for knee bursitis is typically excellent. Moderate bursitis deals with spontaneously with rest. More substantial bursitis can need medications (either taken by mouth or in your area injected) to lower inflammation. Contagious bursitis requires drain, perhaps surgical resection, and antibiotics.

Can knee bursitis be prevented?

To the level that the bursitis is triggered by injury or athletic activity, it can be avoided by avoiding reinjury to the bursa and surrounding tissues.
