PreventionBy Mayo Clinic staff
Water on the knee is typically the result of a chronic health condition or traumatic injury. To prevent water on the knee, work with your doctor and other members of your health care team to manage the condition or traumatic injury that causes it. For example:
- See your doctor regularly. See your doctor regularly if you have a chronic joint condition, such as osteoarthritis, rheumatoid arthritis or gout.
- Follow through on your doctor's orders. Take the medications your doctor prescribes to treat the underlying disease or condition that causes water on the knee. If your doctor, physical therapist or sports trainer recommends you wear a knee brace because of a prior injury, be sure to follow through.
- Strengthen your thigh muscles. If your thigh muscles are weak, your doctor may refer you to a physical therapist to learn how to strengthen these muscles to better support your knee.
- Be gentle with your knees. If you're overweight and plan to start exercising as part of a weight-loss program, select an activity that doesn't place continuous weight-bearing stress on your knee joints — such as water aerobics or swimming.
