Have you ever noticed that the front of your knee suddenly swells up and hurts so much that you can't even touch it? Maybe you can't even bend or straighten your knee. It's not good when something like this happens, right? This is a condition that can cause symptoms like this, called `Prepatellar Bursitis`. Let's talk about this simply, in a way that you can understand.
What is `Prepatellar Bursitis`?
Simply put, this is when a small fluid-filled sac called a bursa , located in front of your kneecap, the patella , becomes inflamed. The function of this bursa is to reduce friction during knee movements, acting like a cushion. However, if there is any impact, infection, or damage to this fluid sac, more fluid begins to accumulate inside this fluid sac. This is when the bursa swells, putting pressure on other parts of the knee. Often, this swelling can be clearly seen in front of the knee.
This condition is called by other names. You may have heard of it:
- `Housemaid's knee` (because people who clean houses often kneel)
- `Carpenter's knee` (That's what carpenters do)
- `Coal miner's knee` (also occurs in people who work in coal mines)
- `Carpet layer's knee`
What are the types of `Prepatellar Bursitis`?
There are two main types of `Prepatellar Bursitis`:
`Acute Prepatellar Bursitis`
This is when the bursa is damaged suddenly. Most often, this is caused by a strong blow to the knee (trauma) or a bacterial infection . Imagine, you suddenly hit your knee somewhere, or you have a small wound on your knee that has become infected.
``Chronic Prepatellar Bursitis''
This takes a while to develop. This condition occurs when the knee is used continuously, especially from things like frequent kneeling, which puts constant pressure on the bursa.
What are the symptoms of `Knee Bursitis`?
Okay, now let's see what symptoms this `Knee Bursitis` presents. The symptoms may vary depending on the severity of the condition. But there are three common symptoms. Not all three need to be present, however.
- Knee pain: Some people experience knee pain even when standing still, and pain when straining. Others experience no pain when standing still, but experience pain when bending or twisting their knees.
- Swelling in the front of the knee: You can see this swollen `bursa` through the skin and feel it with your hand. It usually feels soft when pressed with your hand.
- Limited knee range of motion: If you have severe prepatellar bursitis, you may not be able to bend or straighten your knee normally.
Now, if the cause of this `Knee Bursitis` is an infection, there may be some additional symptoms:
- The skin on the swollen knee may be red, pink, or purple .
- The swollen area of the knee may feel warmer than other areas.
- You may get a fever .
- You may feel achy and cold .
Most importantly! If you have symptoms of an infection (fever, swelling, redness, warmth), you should see a doctor or go to the nearest hospital immediately. Prepatellar Bursitis that is accompanied by an infection requires medical attention. If left untreated, it can lead to serious, even life-threatening, complications.
What are the causes of `Prepatellar Bursitis`?
Okay, so what causes this `Prepatellar Bursitis`?
- Frequent kneeling: This condition is most often caused by the pressure and irritation of the `bursa` caused by frequent kneeling. For example, when doing housework, gardening, and in some jobs (carpentry, tilers), people often have to kneel.
- Direct blow to the knee: This can occur due to trauma, either from a fall or something hitting the knee.
- Bacterial infection: If you have a sprain, insect bite, or cut on your knee and it becomes infected, the infection can spread to your prepatellar bursa. This is called infectious bursitis .
- Rheumatoid arthritis and/or gout: Although these are not very common, the conditions rheumatoid arthritis and gout can also cause prepatellar bursitis.
Who is at higher risk of developing this?
Anyone can develop `Prepatellar Bursitis`, but the following people are at higher risk:
- For people between 40 and 60 years old.
- For men.
- For those who do jobs or hobbies that require frequent kneeling , such as carpentry and gardening.
- For those who play sports that can cause severe blows to the knees, such as football, wrestling, and rugby.
- For those with a health condition that weakens the immune system.
Complications that may occur if left untreated
As I mentioned earlier, if untreated, Prepatellar Bursitis with an infection can lead to serious conditions like septic shock, and even death . Therefore , it is essential to seek medical advice immediately if there are signs of infection.
How do doctors diagnose this?
How does a doctor accurately diagnose `Prepatellar Bursitis`?
First, the doctor will ask you about your symptoms and your health history. Then, they will do a physical exam, focusing on your knee. They will check for knee pain, tenderness, and range of motion.
Sometimes, imaging tests may be performed to confirm the presence of `Knee Bursitis` or to rule out another medical condition.
Diagnostic tests
Here are some tests that doctors use to diagnose Prepatellar Bursitis and to check for other causes:
- Knee X-rays: An X-ray may be done to see if a bone disorder is causing your pain and swelling.
- CT scan or MRI: A CT scan or MRI may be done to see if there is any damage to the soft tissue in or around the knee, or if it is causing the swelling.
- Ultrasound: An ultrasound can be performed to determine if you have inflammation of the prepatellar bursa or another condition such as pes anserinus bursitis.
- Prepatellar bursa aspiration: If your doctor suspects that you have an infection in your bursa, he or she will use a thin needle to take (aspirate) some fluid from the bursa and test it for bacteria.
How to treat `Knee Bursitis`?
Treatment for `Prepatellar Bursitis` depends on the severity of the condition. In most cases, cases of `Prepatellar Bursitis` that are not infected, but are simply inflamed, can be treated at home without medical intervention. However, if the cause is an infection, it will need to be treated with `antibiotics` .
Treatment for non-infectious bursitis:
- Rest and limit certain activities: Stay away from activities and movements that aggravate your symptoms as much as possible until the bursitis is better.
- Ice application: Applying ice to the knee at regular intervals can reduce swelling and pain.
- Elevating the leg: When resting, try to elevate the leg with the affected knee slightly.
- Compressing the knee: Compression helps reduce swelling.
- Taking painkillers and non-steroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen and naproxen, can help reduce pain and inflammation.
- Bursa injection: In some cases, if rest and anti-inflammatory medications do not help, the doctor may give a steroid injection into the bursa to reduce inflammation.
Treatment for an infected bursitis:
- Antibiotics: Antibiotics are essential to treat a bacterial infection. Your doctor may give you antibiotics either by mouth or intravenously (IV).
- Surgical drainage: If antibiotics alone do not control the infection, your doctor may need to surgically drain your prepatellar bursa.
- Bursectomy: If the infection does not clear up with antibiotics and surgical drainage, your doctor may need to completely remove your bursa in a single operation (bursectomy).
When should I see a doctor?
As I said before, if you have symptoms of an infection , such as fever and chills, see a doctor or go to the nearest hospital immediately. Prepatellar Bursitis with an infection requires immediate medical attention.
How to prevent `Prepatellar Bursitis`?
There are several things you can do to prevent this `Prepatellar Bursitis` from occurring:
- Using knee pads: If you have a job that requires you to kneel frequently, or if you play a sport that can put pressure on your knees, wearing knee pads can act as a cushion for your knees and reduce the pressure on the bursa.
- Preventing Infection: If you have a cut or insect bite on your knee, keep it clean to prevent infection from spreading to the bursa.
- Ice and Elevate Your Knees After Exercise: After doing activities or exercises that involve frequent kneeling, squatting, or other activities, apply ice and keep it on your legs.
What is the prognosis of this condition?
Most cases of prepatellar bursitis can be treated with home remedies such as rest, ice, compression, and elevation of the leg. Swelling and other symptoms usually go away within two to three weeks , and there are no long-term side effects. However, if prepatellar bursitis does not improve after two to three weeks of rest, see your doctor.
Chronic knee bursitis can be difficult to treat, especially if you have a job that requires you to kneel frequently. Your medical team will develop a treatment plan that best suits you and your condition. If left untreated, Chronic Prepatellar Bursitis can last for months, even years.
Your knee is a hard-working joint. We often don't think much about it until it's a problem. Prepatellar bursitis is a common condition that can often be treated at home with things like rest, ice, and elevating your leg. However, if your symptoms continue to affect your daily life or don't improve after a few weeks, see your doctor. They can develop a treatment plan that's right for you. If you have signs of infection, such as a fever or warmth in the affected area, be sure to seek medical attention as soon as possible.
So, let's remember these things?
- `Prepatellar Bursitis` is an inflammation of the fluid-filled sac called the `bursa` located in front of the kneecap.
- Frequent kneeling, a blow to the knee, or an infection can be the main causes.
- If you experience symptoms such as knee pain, swelling, redness, and fever , see a doctor.
- If there is no infection, it often heals with simple things like rest and ice.
- If there is an infection, you need to seek treatment immediately.
- Things like using knee pads and keeping wounds clean can help prevent this.
