Knee effusion
Hello Doctor, I have been experiencing discomfort in my knee for 2 to 3 years.
When I squat down, my right knee makes a popping sound, and I feel a momentary weakness along with some pain.
I previously consulted a doctor who performed an ultrasound and mentioned that my right knee did not develop properly and has fluid accumulation.
I was advised to take medication and undergo rehabilitation, but there has been no improvement.
I also experience knee discomfort when performing deep squats during weight training, and I am afraid of the popping sound and the sudden weakness causing me to drop the barbell.
This situation is very troubling for me.
Could you please advise on how to restore my knee to normal? I really appreciate your response, Doctor.

Hello: The noise in the knee joint is often caused by incomplete development of the synovial membrane folds within the joint.
If it is accompanied by pain that makes squatting difficult, it is advisable to visit an orthopedic clinic for an examination.
Thank you!

More Info
Knee effusion, commonly referred to as "water on the knee," is a condition characterized by the accumulation of excess fluid in or around the knee joint. This condition can arise from various causes, including injury, inflammation, or underlying medical conditions. Understanding the causes, symptoms, and treatment options for knee effusion is crucial for effective management and recovery.
Causes of Knee Effusion
1. Injury: Trauma to the knee, such as ligament tears (e.g., ACL or MCL injuries), meniscus tears, or fractures, can lead to swelling and fluid accumulation. In your case, the history of knee discomfort and the audible "pop" sound during squatting may suggest an underlying injury.
2. Inflammation: Conditions such as arthritis (osteoarthritis or rheumatoid arthritis) can cause inflammation of the knee joint, leading to effusion. Inflammatory responses can result from wear and tear on the joint or autoimmune processes.
3. Infection: Septic arthritis, an infection in the joint, can lead to significant swelling and pain. This is a medical emergency and requires prompt treatment.
4. Overuse: Repetitive activities, especially those involving heavy lifting or deep squats, can irritate the knee joint and lead to fluid accumulation.
5. Bursitis: Inflammation of the bursae (small fluid-filled sacs that cushion the knee joint) can also contribute to effusion.
Symptoms of Knee Effusion
The primary symptom of knee effusion is swelling around the knee, which may be accompanied by:
- Pain or tenderness in the knee
- Stiffness or reduced range of motion
- A feeling of tightness in the knee
- A "popping" or "clicking" sensation during movement
- Warmth or redness around the joint
Treatment Options
1. Rest and Activity Modification: Avoid activities that exacerbate the pain, such as deep squats or heavy lifting. Allowing the knee to rest can help reduce inflammation and fluid accumulation.
2. Physical Therapy: Engaging in a structured rehabilitation program can strengthen the muscles around the knee, improve stability, and enhance range of motion. A physical therapist can tailor exercises to your specific needs, focusing on strengthening the quadriceps and hamstrings, which support the knee joint.
3. Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. However, if you have allergies to NSAIDs, alternative pain relief options should be discussed with your healthcare provider.
4. Aspiration: In cases of significant effusion, a healthcare provider may perform a procedure to aspirate (drain) the excess fluid from the knee joint. This can provide immediate relief and allow for further evaluation of the fluid.
5. Corticosteroid Injections: If inflammation is a significant issue, corticosteroid injections into the knee joint may help reduce swelling and pain.
6. Surgery: If conservative treatments fail and the underlying cause is severe (e.g., significant meniscus tear or ligament injury), surgical intervention may be necessary. This could involve arthroscopy to repair damaged structures within the knee.
Prevention Strategies
To prevent further knee issues, consider the following:
- Strength Training: Focus on strengthening the muscles around the knee to provide better support and stability.
- Proper Technique: When performing exercises like squats, ensure proper form to avoid undue stress on the knee joint.
- Gradual Progression: Increase the intensity of your workouts gradually to avoid overuse injuries.
- Use of Supportive Gear: If necessary, consider using knee braces or supports during activities that put stress on the knee.
Conclusion
Knee effusion can be a complex condition that may require a multifaceted approach for effective management. Given your history of knee discomfort and the lack of improvement with previous treatments, it may be beneficial to consult with an orthopedic specialist for a comprehensive evaluation. They can provide a tailored treatment plan based on the specific underlying issues contributing to your knee effusion. Early intervention and appropriate management can significantly improve your quality of life and restore your ability to engage in activities without discomfort.
