Fluid on the knee -- also referred to as a knee effusion or water on the knee -- means there is excessive fluid building up around your knee joint, according to MayoClinic.com. Fluid on the knee can be the result of a number of ailments, including overuse injuries, traumatic injuries, infection and disease. A knee effusion can cause swelling, pain and stiffness, making daily activities and participating in your favorite physical activities difficult. Fortunately, there are ways of relieving fluid on the knee.
Step 1
Try home-care methods first. If you experience knee pain, stiffness and swelling, try resting your knee for a few days. Avoid physical activity, and stay off of your knee as much as possible. Try icing your knee for 20 minutes at a time, three to four times per day. You should also elevate your leg above your heart for as much as possible during the first 24 hours after injury or onset of pain. Take over-the-counter anti-inflammatory medications for pain relief.
Step 2
If your pain does not subside after a few days of home care, make an appointment with your physician. He or she can help diagnose the problem and come up with a treatment plan. Tests may include a blood test to test for infections, an X-ray, MRI or joint aspiration to examine the fluid in your knee.
Step 3
Weigh your treatment options. Your doctor will provide you with treatment options. Depending on your diagnosis, treatment may include prescription pain medication, steroid injections, antibiotics, joint aspiration and surgery. Arthroscopic surgery can help diagnose and fix knee problems as well. A total joint replacement may be recommended as a last resort.
