Fluid in the knee, often referred to as joint effusion, occurs when there's an abnormal buildup of fluid in and around the knee joint. According to provided references, this increase in fluids in the tissues around your joint causes the knee to swell up.
Understanding Joint Effusion
Joint effusion isn't just limited to the knee; it can affect other joints like the shoulder or ankle. It's a symptom indicating an underlying issue within the joint.
Causes of Fluid Buildup
While the provided reference doesn't detail specific causes, fluid buildup in the knee (joint effusion) can occur due to:
- Injury: Trauma to the knee, such as a ligament tear or cartilage damage.
- Overuse: Repetitive stress or strain on the knee joint.
- Arthritis: Conditions like osteoarthritis or rheumatoid arthritis.
- Infection: In rare cases, an infection within the joint.
Treatment and Home Care
The reference mentions that treatments aim to address the cause of the swelling. Furthermore, you can take actions at home to help heal the joint effusion:
- Rest: Avoid activities that aggravate the knee.
- Ice: Apply ice packs to the knee for 15-20 minutes at a time, several times a day.
- Compression: Use a compression bandage to reduce swelling.
- Elevation: Keep the knee elevated to help drain excess fluid.
- Medical Consultation: Consult with a healthcare provider is crucial for proper diagnosis and treatment of underlying cause.
