Medical terms 

  • Prepatellar inflammation (also referred to as housemaid’s knee, carpet layer’s knee, coal miner’s knee or carpenter’s knee) is inflammation of the bursa (a fluid-filled sac) that's ahead of your kneecap (patella). Prepatellar bursitis happens once your bursa is often irritated, broken or infected and makes an excessive amount of fluid. The additional fluid causes your bursa to swell and puts pressure on alternative elements of your knee. you'll be able to usually “see” prepatellar bursitis as a result of the front of your knee can look swollen.

  • Prepatellar bursitis is the inflammation of a small fluid-filled sac (bursa) located in front of the kneecap (patella). This condition is also known as “housemaid’s knee” or “clergyman’s knee.” The bursa acts as a cushion between the kneecap and the skin. Bursitis occurs when the bursa becomes inflamed.

  • Prepatellar bursitis is when the small, fluid-filled sac in front of your knee becomes irritated or inflamed. It can happen when you kneel a lot, like when you’re scrubbing floors or gardening. When it gets inflamed, it can swell and hurt. The bursa is a small sac of fluid that sits in front of your knee.

What is a bursa?

An adult person has over one hundred fifty bursae (plural for “bursa”) throughout their body. A bursa may be a small, fluid-filled sac that cushions a neighborhood wherever your bone would otherwise rub on your muscle, tendons or skin. By artifacting these areas, bursae facilitate stop friction and inflammation.

Once your bursa sac is repeatedly irritated, broken or infected, its skinny lining thickens and makes extra fluid. The additional fluid collects in your bursa sac and causes it to swell. This is often referred to as bursitis. inflammation most frequently happens to bursae around joints. Prepatellar bursitis is that the second commonest type of inflammation

Symptoms Knee bursitis

Signs and symptoms of knee bursitis vary depending on which bursa is affected and what caused the inflammation

In general the affected part of your knee might feel warm and tender when you put pressure on it You might also feel pain when you move or even at rest

A sharp blow to the knee can cause symptoms to appear rapidly But most cases of knee bursitis result from friction and irritation of the bursa that occurs in jobs that require a lot of kneeling on hard surfaces — so symptoms usually begin gradually and they can get worse over time

When to see a doctor

The bursa a small sac inside the knee joint sometimes becomes infected If you have pain swelling and a fever in your knee see your doctor

Causes Knee bursitis

If you have a bursa it is because of some form of irritation Irritation can come from pressure trauma or inflammation Your body produces synovial fluid to lubricate the joint and its surrounding structures so they move smoothly over each other Bursas are small inflatable sacs that receive this fluid when there is joint movement When the fluid enters the bursa-sac it acts as a cushion between two structures that rub together If you keep moving without rest or further aggravate the area by excessive use or abnormal movement then inflammation results and causes irritation that leads to pain and puffiness around.

Knee bursitis can be caused by:

  • Pressure on your knees: kneeling especially on hard surfaces

  • Overuse or strenuous activity

  • A direct blow to your knee

  • Bacterial infection of the bursa

  • Complications from osteoarthritis rheumatoid arthritis or gout in your knee can include:

  • Participation in certain sports.Sports that result in direct blows or frequent falls on the knee — such as wrestling football and volleyball — can increase your risk of bursitis Runners can develop pain and inflammation in the pes anserine bursa situated below the joint

  • Obesity and osteoarthritis.Pes anserine bursitis is a chronic condition that affects the inner side of your knee below the joint It is more common in obese women with osteoarthritis

Prevention Knee bursitis

  • Achieve and maintain a healthy weight.This can help take the pressure off of your knee

Does stretching help knee bursitis?

According to the American Academy of Orthopaedic Surgeons knee pain can be caused by several conditions including osteoarthritis bursitis and tendinitis Runners cyclists and other athletes strain the knees on a regular basis Occasionally taking a break from physical activity or switching to new exercises that are less intense can help prevent knee injuries A consistent stretching regimen may also help reduce feelings of stiffness and soreness in the knees.

Is walking good for bursitis?

But there are a number of benefits that walking can provide for your bursitis Walking helps reduce inflammation and swelling in the affected area which two very common symptoms of bursitis While treating your pain with ice may be effective in reducing inflammation and swelling it is not always practical to apply ice to the inflamed area around-the-clock Walking offers an alternative option – one that is available all day long at any moment.

What can be mistaken for bursitis?

Athletes and non-athletes alike can experience symptoms that are mistakenly diagnosed as bursitis Activities that cause inflammation include: Repetitive motions such as scrubbing floors or raking leaves which apply pressure to joints while they're in motion Pulling and lifting objects with your arms particularly if you have osteoarthritis in the shoulder Heavy lifting without warming up first Overexertion after minor injuries like twisted ankles or knees pulled muscles and strains.

How do you get rid of knee bursitis?

Knee bursitis or inflammation of the fluid-filled sacs that cushion and protect your knee occurs in both adults and children With regular activity it may disappear with no treatment within a few weeks If left untreated however the bursa can become swollen and painful for months Dry Needling Therapy: Knee dry needling is an evidence based treatment for: • Muscular pain (e.g. sports injuries) when standard treatments have failed to help.

What does knee bursitis feel like?

Knee Bursitis or “housemaid’s knee,” is an inflammation of the small sac that lies above the kneecap The pain and swelling may get so bad that you can’t bend your knee and walking becomes unbearable Knee Bursitis happens most commonly to people who are middle-aged or elderly but it also affects athletes whose knees take a pounding every day—like ballerinas football players and ballet dancers.

Diagnosis Knee bursitis

Doctors often make a diagnosis of knee bursitis after obtaining a medical history and performing a physical exam Your doctor will:

  • Compare the condition of both knees to see if only one knee is hurting

  • You can feel heat swellings on your knee by gently pressing on the area

  • If the skin above the tender area is red or has other signs of infection it needs to be examined

  • To determine if your knee hurts when you bend it or flex it move your legs and knees to see how far you can extend them

Imaging tests

To help rule out injuries that cause signs and symptoms similar to those of bursitis your doctor might request one or more of the following imaging tests:

  • X-ray.These X-rays can be useful in revealing a problem with a bone or arthritis

  • MRI.MRIs use radio waves and a powerful magnetic field to produce detailed images of structures within your body This technology can visualize soft tissues such as bursae which are fluid-filled sacs that help to cushion joints

  • Ultrasound.Ultrasound has the ability to produce images in real time It can be used to more clearly visualize swelling in a bursa


If your doctor suspects that you have an infection or gout in the bursa he/she may take a sample of the fluid present in this area and test it for pathogens by inserting a needle into the affected area and extracting some of the fluid This can also be used as treatment to reduce inflammation

Surgical and other procedures

The more invasive treatments for knee bursitis include:

  • Corticosteroid injection.If the bursitis is severe and not responding to basic treatments your doctor might inject a corticosteroid drug into an affected bursa to reduce inflammation The inflammation usually subsides rapidly but you might have pain and swelling from the injection for a couple of days

  • Aspiration. Your doctor might aspirate the bursa to reduce excess fluid and treat inflammation He or she will insert a needle into the affected bursa and draw fluid into the syringe Aspiration might cause short-term pain and swelling but it is not likely to require immediate treatment You might need to wear a knee immobilizer for a short period after aspiration is performed To reduce the chance of recurrent swelling an injection can be given to the affected area

  • Surgery.If you have severe chronic or recurrent bursitis and don't respond to other treatments your doctor might recommend surgery
