Knee Joint Effusion - Symptoms, Causes & Prevention

Dr. Pramod Bhor May 15, 2024

What is Knee Joint Effusion?

Water collection on the knee is medically known as knee effusion and is a condition in which there is an excess of fluid accumulation in and around the knee joint. Some of the most common causes of this condition include arthritis and injury to the ligaments present in the cartilage in the knee. The presence of fluid in acceptable amounts is a normal phenomenon in joints. However, in certain conditions such as rheumatoid arthritis excess fluid can build up thus making the knee puffy and swollen.

Knee Joint Effusion Symptoms

The build-up of excessive fluid in the joint areas results in puffiness around the bony parts of the knee. This can occur unilaterally and can cause difficulty while bending or straightening the knee joint.

The common water in knee symptoms include:

  1. Swelling or puffiness
  2. Stiffness in the joint
  3. Reduced motion in the knee

Certain symptoms require immediate medical attention. These include:

  1. Inability to stand or put weight on the joint
  2. Fever
  3. Loss of sensation and pulse below the knee

Knee infusion or fluid accumulation in the knee can be caused due to certain underlying conditions. These can cause discomfort and difficulty in performing daily functions.

Causes of Knee Effusion

Generally, arthritis, infection, or traumatic injuries can result in swelling and inflammation of the knee joint. This results in fluid build-up in the knee that can cause discomfort and disability in extreme cases. The type of fluid accumulation in the knee depends on the underlying condition or the type of traumatic injury.

3. Traumatic injury 

Traumatic injuries can result in bruising and severe pain in the joint that can lead to discomfort while walking and while putting weight on the knee joint.

4. Septic arthritis 

This is a painful infection in the joint that is a result of germs that travel throughout the bloodstream originating from another part of the body.

5. Gout

This is a form of arthritis that results in extreme pain, inflammation, and tenderness in joints.

6. Pseudogout

This is a temporary episode of a painful type of arthritis that results in swelling in one or more of the joints. These episodes last for days or weeks in some cases. 

7. Tuberculous arthritis

This type of arthritis is caused due to an infection of the joints due to the presence of tuberculosis. 

8. Juvenile rheumatoid arthritis

This form of arthritis is the most common type affecting children and is characterized by inflammation in the joints that is short-term or can even last for a lifetime. 

9. Wear and tear due to sports

Certain strenuous physical activities or sports can lead to the breakdown of the knee joint in extreme cases. 

How can water on the knee be prevented?

There are certain precautions and lifestyle changes that can be made to prevent knee effusion. It is recommended to seek medical advice if there is any new or sudden swelling in the knee. Immediate medical attention is required if there is no sensation of pulse below the knee along with a fever.

  1. Avoid high-impact sports activities on a daily basis 
  2. Avoid sudden jerking or jolting movement in the joints 
  3. Maintain an optimum body weight 
  4. Avoid repetitive movements 
  5. Seek medical attention for existing arthritis


Is knee effusion serious?

Knee effusion, or the accumulation of excess fluid in the knee joint, can be a serious condition if it is left untreated or is caused by an underlying injury or disease. It can cause pain, swelling, and difficulty moving the knee joint. It is important to seek medical treatment to determine the cause and address any potential underlying issues.

Can knee effusion go away by itself?

It is possible for knee effusion (excess fluid in the joint) to resolve on its own, particularly if it is caused by minor inflammation or injury. However, if the underlying cause is not addressed, the effusion may persist or reoccur. Seeking medical treatment and following a prescribed treatment plan can help to reduce the risk of long-term issues with knee effusion.

What happens if knee effusion is left untreated?

If knee effusion (excess fluid in the knee joint) is left untreated, it can cause increased swelling and discomfort, difficulty moving the joint, and potentially lead to more serious issues such as joint damage or infection. It is important to seek medical treatment to properly diagnose and address the cause of the effusion.
