Bursitis is inflammation of the fluid-filled sac (bursa) that lies between a tendon and skin, or between a tendon and bone.

The condition may be acute or chronic.

Examples

The most common examples of this condition:

• • Prepatellar bursitis, "housemaid's knee"

  • Infrapatellar bursitis, "clergyman's knee"

  • Trochanteric bursitis, giving hip pain

  • Olecranon bursitis, characterised by pain and swelling in the elbow

  • Subacromial bursitis, giving shoulder pain

Causes, incidence, and risk factors

Bursae are fluid-filled cavities near joints where tendons or muscles pass over bony projections. They assist movement and reduce friction between moving parts.

Bursitis can be caused by chronic overuse, trauma, rheumatoid arthritis, gout, or infection. Sometimes the cause cannot be determined. Bursitis commonly occurs in the shoulder, knee, elbow, and hip. Other areas that may be affected include the Achilles tendon and the foot.

Chronic inflammation can occur with repeated injuries or attacks of bursitis.

Symptoms

You may notice:

• • Joint pain and tenderness when you press around the joint

  • Stiffness and achiness when you move the affected joint

  • Swelling, warmth or redness over the joint

Treatment

Your health care provider may recommend temporary rest or immobilization of the affected joint.

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may relieve pain and inflammation. Formal physical therapy may be helpful as well.

If the inflammation does not respond to the initial treatment, it may be necessary to draw out fluid from the bursa and inject corticosteroids. Surgery is rarely required.

Exercises for the affected area should be started as the pain goes away. If muscle atrophy (weakness or decrease in size) has occurred, your health care provider may suggest exercises to build strength and increase mobility.

Bursitis caused by infection is treated with antibiotics. Sometimes the infected bursa must be drained surgically.

Expectations (prognosis)

The condition may respond well to treatment, or it may develop into a chronic condition if the underlying cause cannot be corrected.

Complications

• • Chronic bursitis may occur.

  • Too many steroid injections over a short period of time can cause injury to the surrounding tendons.

Calling your health care provider

Call your health care provider if symptoms recur or do not improve after 2 weeks of treatment.

Prevention

Avoid activities that include repetitive movements of any body parts whenever possible.

Prepatellar bursitis (housemaid's knee)

Inflammation causes the knee to become tender and swollen, making it difficult and painful to move the joint.

What is prepatellar bursitis?

The knee has 15 bursae, fluid-filled sacs that act as shock absorbers and protect the bones, joints and tendons from the harm friction can cause.

The prepatellar bursa, is located in front of the kneecap (patella). When this becomes inflamed, as the result of repeated friction between the skin and patella, it's known as prepatellar bursitis.

Symptoms

Along with the bursa becoming tender and swollen, complications can arise when fluid within the bursa becomes infected, causing the area to become red, hot and painful.

Top

Causes and risk factors

Friction between the skin and the patella can be caused by someone spending a lot of time on their knees, doing repetitive movements. Inflammation can also occur as the result of injury, infection or an underlying inflammatory condition.

However, often it's not clear why someone has developed a prepatellar bursitis.

Treatment and recovery

Rest is one of the most important treatments. Cold and heat therapy can also be used to relieve inflammation:

• • A bag of frozen vegetables wrapped in a tea towel is a simple means of providing cold therapy.

  • A hot water bottle wrapped in a towel is an effective form of heat therapy.

  • Alternating hot and cold water from a showerhead is another idea.

Painkillers and anti-inflammatory medication such as ibuprofen are also usually recommended.

Persistent fluid accumulation in the bursa increases the risk of further episodes of inflammation. Under these circumstances, the fluid may need to be aspirated, and hydrocortisone may be injected to relieve any inflammation and prevent further fluid accumulation.

If the problem persists despite these measures, surgical excision of the bursa may be necessary.

The best way to avoid inflammation of the bursa is to steer clear of any action that causes repeated friction between the skin and patella.

In some occupations, such as carpet-fitting, this may not be possible, although it's not unheard of for people to change profession because of recurring knee problems.

Infrapatellar Bursitis or Clergyman's Knee: Symptoms, Treatment-Cold Therapy

A bursa is a small sac containing fluid which is responsible for lubrication during movement between bone and tendons.

Infrapatellar bursitis (clergyman's knee) is the inflammation of the infrapatellar bursa located just below the kneecap.

The deep bursa is situated between the patellar ligament and the upper front surface of the tibia.

The superficial bursa is located between the patellar ligament /patellar tendon and the skin.

Friction or chafing between the skin and the bursa results in infrapatellar bursitis. This may sometimes occur along with Jumper's knee.

Symptoms of Infrapatellar Bursitis or Clergyman's Knee

• • Pain in the anterior region of the knee.

  • Swelling in the region of bursa.

  • Pain can be similar to that of jumper's knee.

Treatment of Infrapatellar Bursitis or Clergyman's Knee

• • Rest.

  • Direct pressure on the knee should be avoided such as when kneeling.

  • Cold therapy helps in reducing the pain and swelling.

  • Compression helps in reducing the pain and swelling.

  • Anti-inflammatory medications such as ibuprofen help in pain and inflammation.

  • If patient does not benefit from conservative treatment, then aspiration of the fluid from bursa can be done along with an injection of corticosteroids into the bursa.

  • If all fails, then surgical removal of bursa is done as a last resort.
