Water on the knee is a condition where fluid builds up in the knee joint. Known also as knee effusion, it can happen due to various reasons. These include osteoarthritis, injury, infection, or being overweight. It’s seen more in older people but can also affect the young, especially if they do certain activities a lot or have a family history of it. Signs of this issue are pain, swelling, stiffness, trouble moving, and a noise when the knee moves.
Doctors find out if you have water on the knee by asking about your health, checking your knee, and possibly using pictures like X-rays or MRI scans. Ways to treat it vary. They can start by suggesting weight loss or more exercise, or give you medicine for the pain. In serious cases, you might need shots or even an operation. But these days, a treatment called stem cell therapy stands out. It works by possibly fixing your knee’s cartilage and making the swelling go down.
Key Takeaways:
- Water on the knee, also known as knee effusion, is the accumulation of synovial fluid in the knee joint.
- Causes of water on the knee include osteoarthritis, injury, infection, and being overweight.
- Symptoms of water on the knee can include pain, swelling, stiffness, decreased mobility, and a creaking sound during knee movement.
- Diagnosis is typically made through a physical exam, medical history, and imaging tests.
- Treatment options for water on the knee include weight loss, exercise, pain relievers, injections, and surgery.
- Stem cell therapy has shown promise in cartilage regeneration and reducing inflammation.
Causes and Risk Factors of Water on the Knee
Water on the knee, or knee effusion, has several causes. Knowing about these reasons can help prevent and manage it better.
Osteoarthritis
Osteoarthritis is a big cause of knee effusion. It happens as joints wear down over time. This can damage the cartilage and lead to fluid buildup.
Age
As we get older, the risk of knee effusion increases. This is because our joints have seen more wear and tear. Anyone over 45 starts facing a higher chance of knee problems.
Weight
Being overweight or obese can stress knees more. This extra stress can wear down the cartilage. And, it can lead to more fluid and inflammation in the knee.
Heredity
Your genes can also affect your knee health. If you have certain genetic traits, you might be at a higher risk. These traits can contribute to osteoarthritis and hence knee effusion.
Gender
Women face knee osteoarthritis more often than men after 55. This could be due to hormones and different joint structures. These factors can make women more prone to knee issues as they get older.
Repetitive Stress Injuries
Activities like kneeling or lifting heavy objects can hurt knees over time. This stress can cause swelling and fluid buildup.
Athletics
Playing sports like soccer or running a lot can stress knees too. The constant movement and impact can inflame knees. This can lead to water on the knee.
Other Illnesses
Some diseases can make knee effusion more likely. Conditions like rheumatoid arthritis can cause fluid buildup in knees. Others include troubles like having too much iron.
It’s key to know about knee effusion causes and risks. This helps in preventing it. It also guides on what treatments might work well. By focusing on these areas, one can lower their knee effusion risk and keep their joints healthy.
Diagnosis and Treatment of Water on the Knee
Diagnosing water on the knee uses a physical exam and medical history. Doctors may order x-rays and MRIs too. The exam checks for pain and swelling, while the history looks at past injuries or activities. These help find out why the knee is swollen.
Imaging tests are used to see the joint’s condition. X-rays can show if bones are affected. MRIs give detailed images of soft tissues. They look for any damage or inflammation.
If needed, joint fluid analysis confirms the diagnosis. Doctors remove fluid from the knee to check for infection or other problems. This test is important for the right treatment.
Treatment Options
Once water on the knee is confirmed, the goal is to ease pain and improve movement. Treatment varies based on the cause and how serious the condition is.
Weight loss: Losing weight can lessen knee pressure and pain.
Exercise and physical therapy: These can strengthen the knee muscles and make the joint work better.
Pain relievers: Medications can help with pain and reduce swelling.
Injections: Shots of corticosteroids or hyaluronic acid in the knee can ease pain and swelling.
Surgery: For severe cases, surgery might be necessary. Options include arthroscopy or joint replacement.
The best choice of treatment depends on the person’s health and the knee’s condition. Always talk to a healthcare expert for advice.
| Treatment Options | Benefits | Considerations |
|---|---|---|
| Weight loss | – Reduces pressure on the knee joints – Alleviates pain and inflammation |
– Requires commitment and lifestyle changes – May take time to see significant results |
| Exercise and physical therapy | – Strengthens muscles around the knee joint – Improves joint stability and flexibility |
– Requires regular commitment – May need guidance from a professional |
| Pain relievers | – Provides temporary relief from pain – Reduces inflammation in the knee joint |
– Can have potential side effects – Not a long-term solution |
| Injections | – Delivers targeted pain relief – Helps reduce inflammation in the knee joint |
– Temporary effects – Potential risks such as infection or allergic reactions |
| Surgery | – Can provide long-lasting pain relief and improve joint function – Suitable for severe cases |
– Involves risks associated with surgery – Requires a recovery period |

Stem Cell Therapy for Water on the Knee
Stem cell therapy is a new hope for treating water on the knee. It aims to grow new cartilage and lower swelling. With PRP injections, platelets and plasma from blood are put into the knee. This helps heal and may ease knee effusion symptoms.
MSCs from a person’s own bone marrow can also be used. They are great at making new cartilage and reducing knee joint inflammation. Using the person’s own cells, bone marrow aspirate concentrate boosts the knee’s healing. It might make symptoms better.
Doctors often use patients’ own chondrocytes, too. In this case, cartilage cells are grown and later injected for repair. Though these approaches show promise, more study is required on how well they work and when to use them.
Keep in mind, these treatments can be pricey. The FDA warns against not-approved stem cell treatments. It stresses the importance of safe and regulated practices. Always talk to a doctor before considering stem cell therapy for knee issues.
