Diagnosing A Fluid In The Knee
Visually, a knee with fluid will usually look swollen and puffy. If your physician suspects that fluid in the knee may be an issue, he or she may extract some fluid from the knee using a sterile syringe to assess what type of fluid is present. A lab test may be requested to test for the presence of infection or other types of issues. Your doctor may also suggest an imaging test, such as X-ray , MRI or ultrasound which will help him or her evaluate the situation.
What Are The Causes Risk Factors And Symptoms Of A Bone Spur In The Knee
There is no one answer to the question of what causes bone spurs in the knee. Each case of bone spur can be different but the list we provide here covers the most common causes. These causes are associated with a disease/condition that leads to cartilage degeneration or is a reaction to a bone injury.
Knee osteoarthritis: This is a form of arthritis that is caused by constant wear and tear of the knee joints. With excessive pressure, friction between the knee joints, as well as stretching of the joints, the cartilage in the bones can wear out. When the body attempts to repair itself, it can create bone spurs between the joints.
Knee injuries: A trauma or injury to the knee and specifically the cartilage tissue can cause bone spurs. There are crescent-shaped shock absorbers between the femur and the tibia that when damaged or torn, can cause bone spurs. This is what is often referred to as a meniscus injury.
Age: Data shows that knee pain bone spurs can be a result of natural wear and tear associated with aging. In other words, the older we get, the more likely we are to experience a bone spur.
Other causes: Some people get a bone spur in the knee due to lack of physical activity, nutritional deficiencies, structural abnormalities during birth, or a build-up of calcium deposits in the body. Obesity has also been linked to bone spurs.
- Severe pain in the knee
- Numbness, tingling, or weakness in the knee joint
- Knee stiffness
- Pain when bending or extending the knee
What Are The Most Common Causes Of Joint Effusion
There are several reasons why your knee or other joints might swell with fluid. The most common reasons include:
- Infection. An infection in your joint is called septic arthritis. Septic arthritis is a serious disease that can damage or even destroy your joint. You might need a joint replacement a type of surgery because of it. When you have an infection, your joint tissues can fill with pus. Pus is a protein-rich liquid thats full of dead white blood cells.
- Inflammation. This may be from conditions such as arthritis especially osteoarthritis gout or rheumatoid arthritis.
- Overuse. This is when you use a joint too much. For example, running too hard and often might cause your knee to swell.
- Trauma. A ligament injury or a broken bone are examples of trauma that can lead to swelling. Possible causes of such injuries include contact sports and car accidents.
- Tumor. A mass of tissue that might be benign or cancerous.

The Doctor Should Consider The Problem Worse Than The Patient Is Suggesting
Getting back to the idea that the patient does not know how bad it is. In March 2019, doctors at Brigham and Womens Hospital, Harvard Medical School, Boston University School of Medicine, Weil Cornell Medicine, and the Mayo Clinic released their findings that basically said, patients, do not know how bad their inflammation is. When a patient reports to the doctor that they have problems with swelling, the doctor should consider the problem worse than the patient is suggesting.
Listen to the learning points of the research published in the journal Arthritis Care & Research.
- Synovitis is a prevalent feature in patients with knee osteoarthritis and meniscal tear and is associated with pain and cartilage damage.
- The researchers analyzed data from 276 patients. The patients self-reported their swelling episodes.
- Twenty-five percent of patients reported no swelling,
- 40% of patients reported had intermittent swelling,
- and 36% of patients reported had constant swelling.
When these patients had an MRI. The MRI found much more swelling than the patients reported. The conclusion of this study urged doctors to use caution against using patient-reported swelling as a proxy of inflammation manifesting as effusion-synovitis. In other words, the swelling is worse than the patients think it is. Simply, the knee is worse than they think it is.
What Is Bursitis Of The Knee
Bursitis occurs when one or more of the bursae become irritated and inflamed.
There are more than 150 bursae found throughout the body, and you can experience bursitis in any of your joints. The knee joint is one of the most commonly affected because it regularly undergoes a lot of stress.
Common symptoms of bursitis of the knee include pain, stiffness, redness, swelling, and difficulty moving the joint through a full range of motion.

Surgical And Other Procedures
Treating the underlying cause of a swollen knee might require:
- Arthrocentesis. Removing fluid from the knee can help relieve pressure on the joint. After aspirating joint fluid, your doctor might inject a corticosteroid into the joint to treat inflammation.
- Arthroscopy. A lighted tube is inserted through a small incision into your knee joint. Tools attached to the arthroscope can remove loose tissue or repair damage in your knee.
- Joint replacement. If bearing weight on your knee joint becomes intolerable, you might need knee replacement surgery.
Your doctor might also recommend physical therapy to improve your knee’s function and strength.
Can Fluid On The Knee Get Worse
Yes. Its important to get a correct diagnosis of why your knee is swollen and follow proper treatment. A bacterial infection could spread and lead to permanent cartilage damage. If the problem is an internal tear, youre likely to have long-term, progressively more debilitating pain and loss of mobility if its not treated.

Getting Rid Of Swelling And Inflammation And Degeneration Requires A Health Professional Familiar With Using Inflammation As A Healing Tool
Above we said that a joint that lives in constant inflammation is a joint in a state of unrelenting erosion. Your knee is in a place where it is breaking down faster than your body can repair it. We are not just talking about a piece of the knee like its just the cartilage, or it is just a tendon, or it is just a ligament, it is the whole knee spontaneously degenerating. This is why your whole knee is swelled up.
The focus of our treatment is the strengthening and repair of the knee ligaments. Why is this our focus?
If you want to get rid of chronic knee swelling you must have a treatment that repairs the entire knee. The ligaments are the structures that hold the entire knee together. This means to help repair a meniscus, you must strengthen the ligaments. To heal cartilage damage, you must treat the ligaments. To prevent the recurrence of a Bakers Cyst, you must treat the ligaments. To prevent continued knee degeneration from the destructive forces of osteoarthritis, you must treat the ligaments with a treatment that correctly turns off the inflammation in such a way that beneficial inflammation, the inflammation process that repairs, is left behind to heal the damage.
What Can I Do At Home To Treat Joint Effusion
If your joint swells from fluid, there are a few steps you can take yourself. At-home remedies for joint effusion include:
- Heat, especially moist heat, can help with joint effusion and joint pain. People who have arthritis or a swollen joint because of an injury might want to try heat.
- Ice works well on swollen joints. Try it if you have arthritis or an injury.
- Maintaining a healthy weight to reduce stress on your joints.
- Nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen . NSAIDs help treat the swollen joint of people who are injured or have arthritis.
- Resting your joint effusion might help it heal. Try taking weight off your joint by raising it and use a mobility aid like a cane.

Chronic Knee Swelling Is Developing And Worsening Knee Osteoarthritis
In this video Danielle R. Steilen-Matias, MMS, PA-C offers a brief summary of the constant degenerative process going on in your knee that shows itself every day to you as swelling.
Summary and learning points:
- Many patients tell us that their other health care providers and doctors dismiss or ignore their complaints of knee swelling. However, as research suggests, such as the research examined in this article, is that chronic knee swelling signifies the early development of osteoarthritis.
- The reason the knee is swelling relates to the strength or integrity or lack thereof of the soft tissue around the knee. So the knee swelling can be coming from knee ligament injury or instability. Your body, in an attempt to provide stability for the unstable knee, will swell the knee as a protective mechanism to provide stability to the need temporarily. It should be temporary. Your body is swelling the knee until healing of an injury can take place. The fluid fills the knee to also prevent excessive movement to accelerate healing. When the injury is healed the swelling goes away.
- If you do a job that is very physically demanding, you are on your feet all day, you climb ladders or steps, etc, that is a lot of strain to be putting on your knees and your body does the best it can to provide the swelling necessary to keep your knee together. The problem is chronic swelling is causing a rapid degeneration in the knee.
What Happens During A Joint Aspiration
A joint aspiration may be done on an outpatient basis or as part ofyour stay in a hospital. Procedures may vary depending on yourcondition and your healthcare providerâs practices.
Generally, a joint aspiration procedure follows this process:
You will be asked to remove clothing and will be given a gown to wear.
You will be positioned so that the healthcare provider can easily reach the joint that is to be aspirated.
The skin over the joint aspiration site will be cleansed with an antiseptic solution.
If a local anesthetic is used, you will feel a needle stick when the anesthetic is injected. This may cause a brief stinging sensation.
The healthcare provider will insert the needle through the skin into the joint. You may feel some discomfort or pressure.
The healthcare provider will remove the fluid by drawing it into a syringe that is attached to the needle.
The needle will be removed and a sterile bandage or dressing will be applied.
The fluid sample will be sent to the lab for examination.

Causes Of Water On Knee
While a small amount of fluid is normal for the knee joint, excess of fluid on the knee is a serious indication for some underlying disease.
In medical terminology it is called knee effusion. This excess of fluid can cause joint degradation as time passes.
The accumulation of fluid on the knee can be due to acute cause such as trauma, injury such as fracture, meniscus tear, ligament injury etc. This most often occurs when a person plays sports such as football, tennis etc. The other most important cause is arthritis of the knee joint. Gout and excessive use of knee are other known causes for knee swelling.
Fluid In Knee Symptoms
Symptoms of fluid on knee include:
- Swelling all around the knee.
- Difficult knee joint movements.
- Pain while walking, climbing stairs and various other different activities.
- Stiffness of knee joint.
- In case of septic arthritis, it may turn warm, red and extremely painful.
It is best for you to get a medical checkup in case of fluid on knee your doctor may suggest fluid removal if the fluid is in excess and you are having pain and difficulty in movement.

First Of All You Need To Understand The Basic Anatomy Of Your Knee
Its a synovial joint which means it allows a lot of movement. This degree of movement is made possible largely because of fluid within and around the bones and other soft tissue that make up your knee.
The synovial fluid in the knee basically reduces friction between the joints moving parts, similar to how gear oil helps your car to run smoother. Its also what most people consider water on the knee.
So, if youve ever wondered, is it bad if you have fluid in your knee?
No, its not. Having fluid in the knee joint is actually normal. But, also like gear oil, the problem begins when you have too little or too much.

You may develop a Baker’s cyst. This is when joint fluid leaks out into the back of the knee and causes pain and swelling. Treatment usually involves compression and applying ice packs. However, if your swelling is severe, you may need to have the fluid removed using a fine needle.
You may lose muscle mass, especially in your thigh muscles. This is because fluid in your swollen knee can prevent your thigh muscles from working properly over time this causes them to weaken and deteriorate.
Why Nothing Is Helping You
There may be two reasons that you are reading this article. You did a casual search to see what you can do for your recent knee swelling event, perhaps you worked the long shift in the warehouse, decided to play 27 holes instead of 18, or did something to aggravate your knee beyond normal everyday function. Then you may have landed here because your knee swelling has been going on for years and you have tried everything.
Lets see some stories from the emails we get from people who have tried everything.
I want to return to activities without pain and swelling and tightness and sleep without pain.
Here is a story, probably sounds like many of yours: I want to return to activities without pain and swelling and tightness and sleep without pain. My right knee has been causing me pain for the last five years. It all started with some minor sprains and tears. First was to MCL, then the meniscus had a small tear. I had an MRI and X-rays and the surgeon recommended I get a cortisone shot before considering arthroscopic surgery. The surgery is to clean up some debris.
The cortisone injection did not help. I was prescribed physical therapy which made my knee worse. I was not sleeping so I scheduled the surgery. I am waiting for the surgery now.

Questions To Ask The Doctor
Once you have gotten the appointment, its essential you ask all the necessary questions:
- What is the cause of these symptoms?
- What sort of tests do I need?
- What types of treatment are available?
- I have several other health conditionscan they be treated together?
Furthermore, in order to get a better view of the knee, you may need to request a certain test, depending on the cause.
- X-ray: An x-ray can help rule out broken or bones, and can determine if you have arthritis.
- Ultrasound: Ultrasounds can determine arthritis and other disorders that may be affecting the tendons or ligaments.
- MRI: An MRI can detect anything that an x-ray misses, such as torn ligaments or torn tissues.
You should never try and diagnose your own injuries. If the natural methods dont work, or if the swelling continues and the pain becomes severe to the point where no weight can be placed on it, then contact your doctor immediately. The longer the injury is left untreated, the worse the injury can become.
When To See A Doctor
A swollen knee is a common occurrence. If mild, it can go away on its own after some good rest. However, if it persists for more than three days or gets severe, it could be a serious underlying condition. Medical attention, in this case, will be necessary. Also, see a doctor if your knee prevents you from doing things like bending, walking, or sitting.
Using heat worsens the condition? Therapeutic heat is not recommended in reducing inflammation or swelling.

Joint Or Bursal Aspiration
When a patient has a swollen knee, a doctor may want to verify or rule out certain diagnoses by analyzing the accumulated fluid. To do this, the doctor will remove fluid from the affected knee joint capsule or bursa using a needle and syringe. When performed on a joint capsule, this process is called joint aspiration or arthrocentesis. When performed on a bursa, this process is called bursal aspiration.
The doctor will take note of the aspirated fluid’s color and viscosity and may send it to a lab for further analysis. Determining the contents of the fluid can lead to an accurate diagnosis. For example, uric acid crystals in the joint fluid indicate gout, and bacteria in the fluid indicate infection.
See The Joint Aspiration Procedure
Aspiration and examination of the fluid are important diagnostic steps because the underlying cause of knee swelling will determine the appropriate medical treatment.
Aspirated fluids are not always sent to a lab for analysis. If a diagnosis is already known, a physician may perform an aspiration to improve joint function and patient comfort.
