What Can Cause Swelling Above Knee & What Is Its Treatment

Swelling above knee is a fairly common condition and observed when knee joint or the soft tissues surrounding knee joint is inflamed or injured. Swelling above or over the knee joint is a condition often observed following the knee joint disease. It is sometimes also referred to as water on the knee.

Joints are junctions at which two bones meet with the help of soft tissues or surrounding structures. Swelling above knee indicates accumulation of fluid around the knee joint. Synovial fluid is normally present in the knee joint for lubrication, protection and nutrition of the cells in the joint.1 However, excessive accumulation of fluid in the knee joint causing knee swelling may mean some disturbance in the normal structure and functioning.

What Causes Knee Swelling

Knee swelling is most commonly caused by blood or fluid either inside or around the knee joint. Accumulations of the fluids are usually caused by injury. This is especially true if the swelling in the knee is sudden. Aside from injury, conditions such as arthritis and gout can also lead to knee swelling.

There are four major ligaments associated with the knee joint, and the one that is most prone to injury or tearing is called the anterior cruciate ligament . ACL tears are often sports related, but can be sustained in many other activities. Most of the time, this ligament is torn when too much pressure is put on the knee when jumping or pivoting. Knee swelling from ACL tears is usually very sudden, and is caused by blood rushing to the inside of the knee. In some cases, ACL tears are so severe that reconstructive surgery is necessary, however, with minor tears, the knee often heals on its own within a couple of months.

In many cases, ligament sprains can also lead to swelling in and around the knee. Sprains are generally not as serious as tears, and do not usually require surgery. Most of the time sprains, though very painful, are completely healed within a few weeks time. Unlike ACL tears, swelling resulting from sprains may take several hours or even days to occur, and the fluid buildup in the knee is usually not bloody.

What Is Heart Failure

Heart failure doesnât mean the heart has stopped working. Rather, it means that the heart works less efficiently than normal. Due to various possible causes, blood moves through the heart and body at a slower rate, and pressure in the heart increases. As a result, the heart canât pump enough oxygen and nutrients to meet the bodys needs.

The chambers of the heart may respond by stretching to hold more blood to pump through the body or by becoming stiff and thickened. This helps to keep the blood moving, but the heart muscle walls may eventually weaken and become unable to pump as efficiently. The kidneys may respond by causing the body to retain fluid and salt. If fluid builds up in the arms, legs, ankles, feet, lungs, or other organs, the body becomes congested. Congestive heart failure is the term used to describe the condition.

What To Expect At Your Office Visit

What Does It Mean If My Knee Is Swollen?

Your provider will take a medical history and do a thorough physical examination, paying special attention to your heart, lungs, abdomen, lymph nodes, legs, and feet.

Your provider will ask questions such as:

  • What body parts swell? Your ankles, feet, legs? Above the knee or below?
  • Do you have swelling at all times or is it worse in the morning or evening?
  • What makes your swelling better?
  • What makes your swelling worse?
  • Does the swelling get better when you raise your legs?
  • Have you had blood clots in your legs or lungs?
  • Have you had varicose veins?
  • What other symptoms do you have?

Diagnostic tests that may be done include:

Your treatment will focus on the cause of the swelling. Your provider may prescribe diuretics to reduce the swelling, but these can have side effects. Home treatment for leg swelling that is not related to a serious medical condition should be tried before drug therapy.

Acute Kidney Failure Diagnosis

Your doctor will start with a physical exam. Then, theyâll order tests of your blood, urine, and kidneys.

Blood tests. These measure substances in your blood.

  • Creatinine is a waste product in your blood thatâs made by muscle activity. Normally, itâs removed from your blood by your kidneys. But if your kidneys stop working, your creatinine level rises.
  • Urea nitrogen is another waste product in your blood. Itâs created when protein from the foods is broken down. Like creatinine, your kidneys remove this from your blood. When your kidneys stop working, your urea nitrogen levels rise.
  • Serum potassium is a substance found in your blood that balances water levels in your bloodstream. Kidney disease can cause either high or low potassium levels.
  • Serum sodium is another substance in your blood that helps with fluid balance in your body. High sodium levels can mean that your kidneys arenât working properly because your body canât get rid of the right amount of sodium.

Urine tests. Your doctor will check your pee for blood and protein. Theyâll also look for certain electrolytes. The results help your doctor understand whatâs causing your kidney failure.

Urine output measurement. This measures how much urine you pass in 24 hours. You will get a container to take home, pee into, and then return to the lab after a full 24 hours. It can help your doctor determine why youâre having kidney failure.

Knee Pains – Causes | Knee Pain Reasons | Sudden Knee Pain | Knee Joint Pain Causes | Knee Swelling

When a woman is pregnant, it is normal for some swelling to occur in the feet and ankles. The swelling may be worse if a woman is on her feet during the day.

However, sudden or severe swelling in the legs, ankles, or feet could be a sign of preeclampsia. Preeclampsia is a condition characterized by high blood pressure during pregnancy. It can threaten the safety of the woman as well as the unborn fetus.

Other potential signs and symptoms of preeclampsia include:

  • swelling in the face and hands
  • vision changes
  • nausea and vomiting

Treatment

Preeclampsia subsides after a woman has given birth. A woman should talk to a doctor about the symptoms she is experiencing so the doctor can help to determine the best way to handle the pregnancy.

A person should see their doctor or healthcare provider if they experience any of the following symptoms in the legs and ankles:

  • sudden swelling
  • unexplained swelling
  • additional symptoms, including shortness of breath, fever, and pain

A doctor can help diagnose underlying conditions. In most cases, treating the underlying condition will help alleviate swelling in the legs and ankles.

In some cases, making certain lifestyle changes may help prevent or alleviate swollen legs and ankles. These lifestyle changes include:

  • frequently checking the feet for bruises, cuts, and scrapes, especially if diabetic
  • performing regular exercise

Is This An Emergency

Chronic swelling in the legs as a symptom by itself isn’t typically a medical emergency, Dr. Bhakta said. “Call and make an appointment with your primary care physician or cardiologist. The biggest concern with vein-related leg swelling, he said, is that the signs also could be connected to pulmonary hypertension.

The first thing your primary care physician or cardiologist likely will do is perform an ultrasound examination of your leg veins and an ultrasound of your heart an echocardiogram, Dr. Bhakta said.

The most often recommended non-medical treatment is compression stockings, which compress the veins and ensure that blood continues to flow.

If the exam shows that the valve in a leg vein is deteriorating to a significant degree, your doctor may recommend venous ablation. In this procedure, a medical-grade adhesive seals off the damaged vein.

If your doctor determines that your leg swelling is related to pulmonary hypertension or heart failure , you’ll probably undergo additional tests to determine the best treatment. Treatments for both pulmonary hypertension and heart failure include medications and surgery.

Causes Of Swollen Knee

If your pain and swelling have come on suddenly, it may be due to an injury from playing sport or after an accident or fall. Common injuries include:

  • A fracture
    • Taking nonsteroidal anti-inflammatory drugs eg ibuprofen to relieve your pain
  • Tendinopathy

Chronic swelling, often with night-time pain, could be due to an underlying disease. These conditions, such as arthritis, are more likely as you age.

If you have arthritis, you will have chronic inflammation but you may also have symptoms of acute inflammation. There are different types of arthritis, which can all cause a swollen knee. These include:

  • Gout caused by too much uric acid in your blood
  • Infectious arthritis caused by an infection of a joint that leads to swelling
  • Juvenile arthritis occurs in people aged up to 16 years
  • Osteoarthritis the most common form of arthritis caused by break-down of cartilage in the joints
  • Reactive arthritis usually occurs after an infection of your genitals or urinary tract and becomes chronic this is not common
  • Rheumatoid arthritis your immune system mistakenly attacks your joints

If your doctor thinks your swollen knee could be caused by arthritis, they will ask you about any other symptoms and your medical history. They may refer you for further investigations, such as blood tests or an X-ray.

Treatments for arthritis vary depending on the type you have. They include:

  • Lifestyle changes eg exercise
  • Self-help devices eg easy-grip utensils, jar openers and reachers
  • Surgery

The lymphatic system filters clear fluid that is outside of the veins back into the venous system to be carried back to the heart.

Swelling of the lower legs is common in older adults and is sometimes associated with minor problems, but other potential causes are heart, kidney or liver failure, reports MedlinePlus. For minor problems, elevating the legs or avoiding prolonged standing in the same position often brings relief.
