The knee may become swollen due to injuries to the tendons, ligaments or meniscus. Other health problems, such as arthritis and even overwork, can also contribute to knee swelling. The swelling may manifest in the knee joint or surrounding tissue. People call it “water at the knee “. Once you find that your knee is swollen, you can try treating it at home, but if the swelling doesn’t stop or you hurt too much, you should see a doctor.
Diagnosis of a swollen knee
Compare a sore knee with a healthy one. Look for swelling around the patella or on the sides of the knee. Comparing both knees is a good way to find out if your knee is swollen or red, and therefore if something is wrong.
Swelling can also occur on the back of the knee. Such swelling could be a symptom of Baker’s cyst, which manifests itself when fluid in the knee enters the tissue behind it. In this case, trying to get up can make your knee very bad.
If your knee is redder and warmer to the touch, see your doctor.
Bend and straighten your leg. If you have difficulty moving your legs, there will probably be something wrong that needs to be treated. You may feel pain or stiffness. Stiffness will most likely be due to fluid in the knee.
Try walking. Standing on an injured leg can be painful. Try to stand on your sore leg carefully and see if he can handle a certain load.
See your doctor. Although you can diagnose swelling in your knee, you may not know the exact cause. Therefore, it is better to consult your doctor if the swelling does not subside or is painful.
Swelling of the knees mainly causes injuries such as ligament or cartilage rupture, irritation of the knee overload, osteoporosis, rheumatoid arthritis, gout, infections, bursitis and others.
Make an appointment with a doctor. If you have any major flow, or if you cannot transfer weight to that knee, see a doctor. You should see a doctor if you have any obvious deformity, or if you have a fever or redness in your shin, which are signs of an infection, and also if your knee does not improve after 4 days. It could damage the ligaments.
The doctor will examine your knee, find out what condition your knee is in and what is causing the swelling. He or she may also perform X-ray, ultrasound, or MRI scans to determine if there are any injuries to bones, tendons, or ligaments.
Your doctor may try to aspirate the knee joint to control the infection based on the number of white blood cells and bacteria in the fluid.
Your doctor may apply a steroid to your knee to reduce swelling.
Operation. Depending on the condition of your knee, your doctor may recommend surgery. The most common types of knee surgery include:
Arthrocentesis – removal of fluid from the knee to relieve pressure
Arthroscopy – removal of loose or damaged tissue from the knee
Endoprosthesis – knee replacement. If your knee does not improve and you suffer from unbearable pain, your doctor may suggest a knee replacement.
Visit a physiotherapist. Your doctor may refer you to a physiotherapist who will examine our leg and provide you with exercises to strengthen the muscles around the knee joint based on your condition.
Visit an orthopedist. Other leg problems, such as a flat foot, can also contribute to knee pain and swelling. Visit an orthopedist who will examine your foot. An orthopedist may recommend wearing insoles.
The orthopedist may need to examine your back and hips in addition to your legs. Pain in the back, hips and legs is called transmitted pain.
Prevention of knee swelling
Wear knee pads. Wear padded knee pads if you spend a significant amount of time sitting on your knees, as is the case with some minor landscaping or housework.
If possible, do a “micro break ” for 10-20 seconds as long as possible. During these breaks, get up and stretch your legs to return to a resting position.
Avoid squatting and kneeling. If you want to avoid a swollen knee, try to avoid repetitive movements in which there is a thrust on the knees.
Avoid heavy exercise and sports. Many sports, especially those that require a lot of jumping and running, can be dangerous for the knees. So avoid snowboarding, running and basketball until your knee is fully recovered.
Eat foods with anti-inflammatory effects. Your diet can also contribute to the risk of swelling of the knees or elsewhere in the body. So try to stay away from instant, fried and sweet foods. Increase your intake of fruits, vegetables, proteins and whole grains.
Omega-3 fatty acids have a lot of anti-inflammatory properties. So eat salmon and tuna more often.
Try Mediterranean cuisine. This diet is rich in a variety of proteins, such as fish, chicken and lots of vegetables, olive oil and beans.
Avoid smoking. Smoking reduces the supply of oxygen and blood flow to the body, which limits the ability to regenerate tissue.
Give your knees a rest. Try to use your foot as little as possible, even when walking.
When lying down, keep your knee above heart level and support it with a pillow or sofa back.
If your leg hurts and you can’t transfer weight to it, use a crutch.
Watch your knee. Apply ice directly to the sore spot for 10-20 minutes three times a day to help reduce swelling.
Alternatively, you can use a frozen cold compress or a bag of frozen vegetables (peas, etc.).
Avoid heat for the first 48 hours. If you have suffered an injury that has caused your knee to swell, avoid warming your knee (wraps, hot shower, whirlpool).
Use a compression bandage. Wrap the knee with an elastic bandage to reduce swelling. You can try an elastic bandage with staples that stick to the bandage so you don’t need any additional staples.
You can buy a compression bandage at the pharmacy.
Be careful not to wrap the knee too tightly. If you feel any numbness, strange color or increased pain, the bandage should be loosened.
Gently massage the knee. A gentle massage will help increase blood flow to your knee. If your knee hurts, do not massage it.
Relieve pain with over-the-counter pain medications. You can try anti-inflammatory drugs such as aspirin, paracetamol, naproxen or ibuprofen – these are all anti-inflammatory drugs.
When taking these medicines, the dosing instructions on the package must be followed.
You can also try local painkillers. Consult your pharmacist about their application. You can also try a medicine that contains analgesic lidocaine for pain relief.
