Knee Effusion Causes Symptoms And Treatments
Posted on February 13th, 2017 by Orthopaedic Specialty Group
Knee effusion, commonly known as water on the knee, occurs when excess fluid accumulates in and around your knee joint. This can cause a tremendous amount of pain and discomfort. If you suffer from knee effusion, it is important to be well-informed so that you can make educated decisions about your health and treatment.
Read below to learn about the common causes, symptoms, and treatment options for knee effusion:
Seeing A Doctor Is Important
Because of the detrimental and debilitating effect that knee synovial fluid accumulation can have on a patients life, it is essential to do everything possible to avoid it in the first place. Caution is always recommended when practicing any brusque physical activity. Weight management is also a valid preventative technique as excess weight puts an unnecessary strain upon the joints of the body.
It is also important to listen to your bodys signals and warnings. If you feel pain or discomfort on the knee joint, stop whatever it is you are doing and give your body a chance to rest. Doing this will significantly reduce the risk of suffering any eventual pain, stiffness, and swelling.
Do You Drain Bursitis
If the bursa is also infected with bacteria, surgery is often recommended right away in order to drain pus or remove the entire bursa. But if you dont have an increased risk of complications, you can wait: Then the bursa is only removed if its still inflamed after several days of treatment with antibiotics.

The Problems Of Excess Weight And Obesity Causes More Inflammation
When we suggest to the patient that their knee can benefit from weight loss, we typically hear, I know, I know, or I have been trying. These are the typical responses of someone who has tried to lose weight and is tired of being lectured. Weight gain, like knee osteoarthritis, is a slow methodical problem that cannot be made to go away overnight. To lose weight you must find the inner motivation to do so. Maybe research can help.
In July 2020, researchers writing in the medical journal Skeletal Radiology looked at three patient groups. All the patients had knee osteoarthritis. The three groups were: people with normal weight people who were overweight people who were obese. What they were looking for was a relationship between excess weight and increases knee inflammation. Here are the results:
- Being overweight or obese was significantly associated with a greater prevalence and severity of synovial inflammation imaging biomarkers. Substantial reproducibility and high correlation with knee structural, cartilage compositional degeneration, and pain scores validate the synovial inflammation biomarkers used in this study.
What does all this mean? The more weight, the more inflammation, the more pain, the greater the need for medication, the greater the knee pain, the greater the eventual need for knee replacement.
Inflammation Comes Before Cartilage Breakdown Inflammation Therefore Causes Bone On Bone Not The Other Way Around
Here is what this paper said:
- . . . our results suggest that inflammation of the synovium, which occurs prior to cartilage degradation, is an early event during osteoarthritis initiation and progression.
- Note: Inflammation comes before cartilage breakdown. Inflammation, therefore, causes bone on bone, not the other way around.

How Do I Know If I Have Fluid On The Knee
Do you feel you have water on the knee? Anyone can have knee pain for a few days. You can try to apply ice, elevate your legs above heart level, and rest. However, in some cases, you need to consult your healthcare provider. If you would like to reduce tissue pressure and support muscles and joints, studies show that using taping the knee helps you recover faster from pain, swelling, and inflammation.
If you know you had a serious injury, or you cannot bend or extend the knee, seek a doctors advice.
Causes Of Swollen Knee
If your pain and swelling have come on suddenly, it may be due to an injury from playing sport or after an accident or fall. Common injuries include:
- A fracture
- Taking nonsteroidal anti-inflammatory drugs eg ibuprofen to relieve your pain
Chronic swelling, often with night-time pain, could be due to an underlying disease. These conditions, such as arthritis, are more likely as you age.
If you have arthritis, you will have chronic inflammation but you may also have symptoms of acute inflammation. There are different types of arthritis, which can all cause a swollen knee. These include:
- Gout caused by too much uric acid in your blood
- Infectious arthritis caused by an infection of a joint that leads to swelling
- Juvenile arthritis occurs in people aged up to 16 years
- Osteoarthritis the most common form of arthritis caused by break-down of cartilage in the joints
- Reactive arthritis usually occurs after an infection of your genitals or urinary tract and becomes chronic this is not common
- Rheumatoid arthritis your immune system mistakenly attacks your joints
If your doctor thinks your swollen knee could be caused by arthritis, they will ask you about any other symptoms and your medical history. They may refer you for further investigations, such as blood tests or an X-ray.
Treatments for arthritis vary depending on the type you have. They include:
- Lifestyle changes eg exercise
- Self-help devices eg easy-grip utensils, jar openers and reachers
What Causes Fluid In The Knee
Several issues may cause fluid in knee joints. Some may be infectious. Determining what causes fluid in your knee will inform your treatment plan. Listed below are potential causes of fluid in knees.
- Injury or trauma: This happens when the knee joint receives a direct blow from an outside force. A trauma or injury to the knees tendons, bones, meniscus, bursae, ligaments, or articular cartilage can cause inflammation.
- Knee osteoarthritis: This common type of arthritis causes excessive knee fluid. Knee osteoarthritis is the degeneration of the cartilage around the knee joint due to aging and repetitive stress.
- Rheumatoid arthritis: This autoimmune disease causes the immune system to attack the bodys own cells and damage the delicate lining of the joints.
- Infection: Gonorrhea, tuberculosis, brucellosis, and lyme disease may all affect the knee.
- Gout: When levels of uric acid get too high, the acid will form into microscopic crystals and build up in the joints.
- Bursitis: An inflamed knee bursaa tiny, fluid-filled sac that separates knee bones from nearby tendons and musclescan fill with excess fluid.
- Tumor: Both benign and cancerous masses sometimes infiltrate the knee.
Comprehensive Prolotherapy For Problems Of Knee Instability And Wear And Tear And Bone On Bonerepetitive Inflammation As An Anti
Comprehensive Prolotherapy is an injection technique that uses a simple sugar, dextrose, and in some cases, it is combined with Platelet Rich Plasma Therapy to address damage and micro-tearing of the ligaments or soft tissue in the knee. A series of injections are placed at the tender and weakened areas of the affected structures of the knee. These injections contain a proliferant to stimulate the body to repair and heal by inducing a mild inflammatory reaction.
The localized inflammation causes healing cells to arrive at the injured area and lay down new tissue, creating stronger ligaments and rebuilding soft tissue. As the ligaments tighten and the soft tissues heal, the knee structures function normally rather than subluxing and moving out of place. When the knee functions normally, the pain and swelling go away.
In published research in the Journal of Prolotherapy, we investigated the outcomes of patients receiving Prolotherapy treatment for unresolved, difficult-to-treat knee pain at a charity clinic in Illinois. Here are the bullet points of our research:

What Is The Best Treatment For A Swollen Knee
Basic treatment for a swollen knee should start with the RICE formula Rest, Ice, Compression , Elevation and analgesics such as paracetamol and ibuprofen.
Please visit this page for more on the RICE formula.
Many people will quickly begin treatments such as physiotherapy, chiropractic or osteopathy, without getting a clear knee pain diagnosis.
If you take this approach, you may have to go through a great deal of pain and spend lots of time and money on the wrong treatment without getting any better .
In This Case Excess Fluid In The Knee Is Essentially What Joint Effusion Is
Research from the Journal of The Royal Society of Medicine says that knee effusion is more common than in any other joint because of 2 connected reasons:
- You bear weight on it, but
- Your knee joint isnt as congruent as your other weight-bearing joints
Soft tissues such as the menisci right in the middle of the joint, as well as the ligaments and joint capsule that tie them all together, make up for the incongruency.

How To Drain Fluid From Knee At Home
While you technically cant drain fluid without the help of a professional, there are a few home remedies that can reduce inflammation at the site of your injury. These include the following:
- RICE method
- Massage , and
- Isometric exercises
For more information on how to drain fluid from knee at home, theres a section near the top of this page that describes these methods in detail.
What Does 18 Months Of Continued Inflammation Do To Your Knee When You Have A Meniscus Tear
Early in January 2019, the same research team published in the journal Arthritis & Rheumatology a study of 221 patients with knee osteoarthritis and meniscal tear. They examined these patients over a time period of 18 months.
- effusion-synovitis was persistently minimal in 45.3% and persistently extensive in 21.3% of the patients.
- The remaining 33.5% of the patients had minimal synovitis on one occasion and extensive synovitis on the other.
- Patients with extensive effusion-synovitis at baseline persistently extensive effusion-synovitis had a significantly increased risk of progression of cartilage damage depth. .

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.
Why Is Your Knee Always Swollen
The simple answer to why is your knee is always swollen is because it is in a constant state of injury. Your immune system is constantly sending fluids to help cushion your knee and repair damaged tissue and remove dead tissue. The problem is, thhe knee is beyond its ability to repair the damage in your knee and the fluids remain constant.
So then, why is your knee always swollen?
- You have swelling because your knee lives in a toxic, inflammatory environment and that toxic inflammation runs deeper than conservative anti-inflammatory care can handle.
- The swelling is a toxic soup. It bathes your knee in a constant inflammation that causes knee breakdown.
- As your knee is in a corrosive state where it is breaking down faster than your body can repair it you get caught in a cycle breaking down causing swelling, swelling causing breakdown.
- The inflammatory process is corrosive. This is why there is an urgency to shut down the inflammation to stop knee destruction.

What Happens After A Joint Aspiration
Once you are home, it is important for you to keep the joint aspirationsite clean and dry. Leave the bandage in place for as long asinstructed by your healthcare provider.
The aspiration site may be tender or sore for a few days after thejoint aspiration procedure. Take a pain reliever for soreness asrecommended by your healthcare provider. Aspirin or certain other painmedicines may increase the chance of bleeding. Be sure to take onlyrecommended medicines.
Notify your healthcare provider to report any of the following:
Fever of 100.4°F or higher, or as directed by your healthcare provider
Redness, swelling, bleeding, or other drainage from the aspiration site
Increased pain around the aspiration site
Your healthcare provider may give you additional or alternateinstructions after the procedure, depending on your particularsituation.
Knee Effusion And Bone Marrow Loss
Knee effusions or water on the knee can harm the muscles and various structures of the knee over time. This may lead to thigh muscle to weaken and atrophy if not treated promptly. Knee joint effusions are also associated with an increase in knee cartilage defects and bone marrow lesions, according to recent studies.
Researchers from the University of Tasmania in Hobart completed a cross-sectional and longitudinal analysis involving more than 900 participants affected by knee effusion. They found that knee effusionsparticularly of the suprapatellar pouchmay be causally related to cartilage defects, which could subsequently lead to bone marrow lesions and cartilage loss over time. Higher grades of effusions were associated with an increased percentage of cartilage defects.
The average age of the participants was 62 years. All underwent MRI of the right knee and assessment of knee synovial effusionsynovitis to obtain a baseline. Contrast imaging using T2-weighted MRI was used to assess different regions of the knee, which included four sub-regions: the suprapatellar pouch, the central portion, posterior femoral recess, and subpopliteal recess.
How To Get Rid Of Water On The Knee Or Fluid On The Knee
All of our joints contain small amounts of fluids that aid their proper functioning. This lubricant helps us reduce friction inside the joint. Joint effusion, or fluid on the knee, occurs when too much of this liquid build up around the joint.
Excessive liquid like this can incapacitate us, make daily activities a real burden, and significantly reduce our mobility. If you suspect that extra fluid is pressing on your knee joint, continue on reading the next sections. This condition is commonly known as Water on the Knee.

What Does A Tumor In The Knee Feel Like
Bone pain and swelling Pain at the site of the tumor in the bone is the most common symptom of osteosarcoma. The most common sites for these tumors in younger people are around the knee or in the upper arm, but they can occur in other bones as well. At first, the pain might not be constant and might be worse at night.

Why Rice And Ice Is Not The Answer
You may be recommended to use ice to reduce the swelling. For many athletes, a doctors recommendation of the RICE protocol for healing their sports-related soft tissue issue injury was seen as the gold standard of care. However, this treatment is now under criticism from a surprising source, the doctor who created the RICE treatment guidelines, Gabe Mirkin, MD.
In a recent article on his own website, Dr. Mirkin admits that both ice and rest may delay healing. This insight comes nearly 40 years after Dr. Mirkin authored The Sportsmedicine Book , where he coined the acronym RICE for the 4 elements which became the standard of care in treating soft tissue injuries- Rest, Ice, Compression, and Elevation. Coaches, physicians, physical therapists, and the lay public have recommended and followed the RICE guidelines for decades, but as Mirkin states:
- it now appears that both ice and complete rest may delay healing, instead of helping.
Knee Arthritis Common Water On The Knee Cause
The two most common types of arthritis are rheumatoid and osteoarthritis. Both of these conditions result in the gradual breakdown of the knee joint but in two completely different ways. Rheumatoid arthritis occurs when the bodys immune system malfunctions and starts attacking otherwise healthy joint tissue. This leads to the joint to slowly degenerate causing pain and inflammation.
According to the Arthritis Foundation, osteoarthritisis the most common type of arthritis affecting over 31 million Americans.Osteoarthritis is characterized by the breakdown of cartilage between the bones in the knee joint. As the cartilage wears, bone on bone friction begins to occur and eventually results in the formation of bone spurs. The lack of cartilage and abnormal bone growth causes joint swelling, pain, and stiffness. Treatment for osteoarthritis depends on a variety of factors, to learn more about the disease check out: Guide to Osteoarthritis Treatment Options

Everything You Need To Know About Water On The Knee
What is it and how is it treated?
Your knee typically has an ounce of liquid inside of it. However, when you have an injury, arthritis, or another problem that irritates your knee, fluid accumulates to cushion and protect your joints.
Clinically, this is known as knee effusion, but most people call it water on the knee.
