What Is Water on the Knee?
Water on the knee, also known as knee effusion or fluid on the knee, is a condition where excess fluid accumulates around and inside the knee joint. This can cause swelling, pain, stiffness, and reduced range of motion in the knee. Water on the knee can affect anyone, but it is more common in older adults, athletes, and people with certain medical conditions.
What Causes Water on the Knee?
There are many possible causes of water on the knee, but some of the most common ones are:
- Injury: Trauma to the knee, such as a ligament tear, cartilage tear, or bone fracture, can trigger an inflammatory response that leads to fluid production. This is the body’s way of protecting and healing the injured tissue. However, sometimes the fluid can be excessive and cause more problems than benefits.
- Arthritis: Arthritis is a group of diseases that cause inflammation and damage to the joints. There are different types of arthritis that can affect the knee, such as osteoarthritis, rheumatoid arthritis, gout, and pseudogout. These conditions can cause the cartilage that covers the ends of the bones to wear away, resulting in bone-on-bone friction and fluid accumulation.
- Infection: Infection can occur in the knee joint or in the surrounding tissues, such as the skin, muscles, or bursae (fluid-filled sacs that cushion the joint). Bacteria can enter the knee through a wound, a surgery, or a blood stream. Infection can cause fever, redness, warmth, and pus in the knee, along with fluid buildup.
- Cysts: Cysts are fluid-filled sacs that can form in or around the knee joint. One common type of cyst is called a Baker’s cyst, which occurs when fluid from the knee joint leaks into a pouch behind the knee. This can cause a bulge and swelling in the back of the knee. Cysts can be caused by injury, arthritis, or other conditions that affect the knee joint.

How Is Water on the Knee Diagnosed?
If you have symptoms of water on the knee, you should see a doctor for a proper diagnosis and treatment. The doctor will ask you about your medical history, your symptoms, and any possible causes of your condition. The doctor will also examine your knee and perform some tests, such as:
- X-ray: An X-ray can show the bones of the knee and rule out any fractures or arthritis.
- Ultrasound: An ultrasound can show the soft tissues of the knee, such as the ligaments, tendons, cartilage, and fluid. It can also detect any cysts or infections.
- MRI: An MRI can provide a detailed image of the knee and show any damage to the structures inside the joint. It can also detect any tumors or other abnormalities.
- Arthrocentesis: Arthrocentesis is a procedure where the doctor inserts a needle into the knee joint and draws out some fluid for analysis. This can help determine the cause and type of fluid, as well as rule out any infection or crystals.
How Is Water on the Knee Treated?
The treatment of water on the knee depends on the cause, severity, and symptoms of the condition. Some of the common treatments are:
- Medication: The doctor may prescribe some medication to reduce the pain, inflammation, and infection in the knee. These may include anti-inflammatory drugs, such as ibuprofen or naproxen, corticosteroids, such as prednisone or hydrocortisone, or antibiotics, such as penicillin or cephalexin.
- Aspiration: Aspiration is a procedure where the doctor uses a needle and syringe to remove the excess fluid from the knee joint. This can provide immediate relief from the pressure and pain in the knee. However, this is not a permanent solution, as the fluid may return if the underlying cause is not addressed.
- Arthroscopy: Arthroscopy is a minimally invasive surgery where the doctor inserts a thin tube with a camera and light (arthroscope) into the knee joint through a small incision. The doctor can then use small instruments to repair any damage to the structures inside the joint, such as removing loose tissue, trimming torn cartilage, or reconstructing torn ligaments. This can help restore the normal function and stability of the knee joint and prevent further fluid accumulation.
- Physical therapy: Physical therapy can help strengthen the muscles around the knee and improve the range of motion and flexibility of the joint. This can help reduce the stress and strain on the knee and prevent further injury or inflammation. Physical therapy may include exercises, stretches, massage, heat, ice, or electrical stimulation.
How Can You Prevent Water on the Knee?
Water on the knee can be prevented by taking some simple steps to protect and care for your knee joint, such as:
- Strengthening your muscles: Strong muscles can support and stabilize your knee joint and reduce the risk of injury or arthritis. You can do some exercises to strengthen your quadriceps, hamstrings, and calf muscles, such as squats, lunges, leg presses, or leg curls. You can also use some resistance bands, weights, or machines to add some challenge to your workout.
- Choosing low-impact activities: Low-impact activities, such as swimming, cycling, or walking, can help you stay fit and healthy without putting too much pressure on your knee joint. You can also avoid activities that involve twisting, jumping, or pivoting your knee, such as basketball, soccer, or tennis, as these can increase the risk of injury or arthritis.
- Maintaining a healthy weight: Excess weight can put extra stress and strain on your knee joint and wear away the cartilage faster. This can lead to osteoarthritis and fluid accumulation. You can maintain a healthy weight by eating a balanced diet and limiting your intake of sugar, salt, and fat. You can also drink plenty of water and avoid alcohol and tobacco.
- Wearing proper footwear: Wearing shoes that fit well and provide adequate cushioning and support can help you avoid injuries and reduce the impact on your knee joint. You can also wear orthotics, such as insoles or arch supports, to correct any foot problems that may affect your knee alignment. You can also wear knee braces, pads, or sleeves to protect your knee from injury or inflammation.
