How Does A Meniscal Cyst Develop

What are the causes of swelling in knees? – Dr.Nagesh HS

Usually, a tear forms in the meniscal cartilage from degeneration or an acute meniscus injury. Fluid from the knee joint then leaks out of the tear, forming a cyst. So, a meniscal cyst is not a true cyst but an outpouching of displaced knee fluid. Also, the cartilage tear can form a one-way valve preventing the fluid from returning to the knee. The liquid then collects as a cyst below the knee cap.

Often, meniscal cysts form in people with a history of a knee injury, cartilage damage, or contact or twisting sports. Also, the presence of arthritis predisposes to the formation of a cyst on the side of the knee.

What Can You Do For The Pain

Your plan will depend on your specific injury. Mild to moderate issues will often get better on their own. To speed the healing, you can:

  • Rest your knee. Take a few days off from intense activity.
  • Ice it to curb pain and swelling. Do it for 15 to 20 minutes every 3 to 4 hours. Keep doing it for 2 to 3 days or until the pain is gone.
  • Compress your knee. Use an elastic bandage, straps, or sleeves to wrap the joint. It will keep down swelling or add support.
  • Elevate your knee with a pillow under your heel when you’re sitting or lying down to cut down on swelling.
  • Take anti-inflammatorymedications. Nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen will help with pain and swelling. Follow the instructions on the label. These drugs can have side effects, so you should only use them now and then unless your doctor says otherwise.
  • Practice stretching and strengthening exercises if your doctor recommends them. You may want to do physical therapy, too.

Make an appointment with a doctor if you still have pain after 2 weeks of home treatment, if the knee becomes warm, or if you have fever along with a painful, swollen knee.

Some people with knee pain need more help. For instance, if you have bursitis, your doctor may need to draw out extra fluid from the bursa in your knee. If you have arthritis, you may need an occasional corticosteroid shot to settle down inflammation. And if you have a torn ligament or certain knee injuries, you may need surgery.

Treatments That Have Already Been Instituted

Many patients have undergone physiotherapy, steroid injection or previous arthroscopy. The success of previous therapies guides further management.

If a patient has not undergone physiotherapy this may be the first port of call particularly in anterior knee pain related to patellofemoral joint dysfunction. History of previous surgery, in particular total knee replacement or cruciate ligament reconstruction, associated with new onset of symptoms should warrant a referral to the orthopaedic surgeon.

Things To Know About Knee Injury

The knee is a hinge joint that has a simple purpose. It needs to flex or extend to allow the body to perform many activities, like running, walking, kicking, and sitting. Imagine standing up from a chair if your knees couldnt bend.

While four bones come together at the knee, only the femur and the tibia form the joint itself. The head of the fibula provides some stability, and the patella helps with joint and muscle function. Movement and weight-bearing occur where the ends of the femur called the femoral condyles match up with the top flat surfaces of the tibia .

Two major muscle groups are balanced and allow movement of the knee joint. When the quadriceps muscles on the front of the thigh contract, the knee extends or straightens.

  • The hamstring muscles on the back of the thigh flex or bend the knee when they contract.
  • The muscles cross the knee joint and are attached to the tibia by tendons.
  • The quadriceps tendon is special, in that it contains the patella within its fibers.
  • The patella allows the quadriceps muscle/tendon unit to work more efficiently.
  • The quadriceps tendon is renamed the patellar tendon from the kneecap to its attachment in the tibia.

The stability of the knee joint is maintained by four ligaments, and thick bands of tissue that stabilize the joint.

Inside the knee, there are two shock-absorbing pieces of cartilage called menisci that sit on the top surface of the tibia.

Pain Swelling And Knee Stiffness

Pin on Fitness

First lets talk about pain: Its the bodys way of preventing you from making an injury worse. Since pain may limit movement, it can cause stiffness in the knees, as can any ongoing injury.

Knees become swollen when excess fluid builds up inside the knee due to an injury, overuse, or medical condition. This can cause sensations of tightness as well as pain. Swelling may be subtle, so you may not always notice it unless its a severe injury. Since the swelling may not be visible, you may feel this as stiffness in the knee.

Any type of swelling will cause limited movement since theres less space in the knee. Irritation, internal bleeding, and injuries in the knee can lead to fluid buildup. Arthritis, gout, and tumors or cysts are conditions that can also cause swelling.

Pain and swelling are two mechanisms your body uses to protect itself. Together they can lead to stiffness in your knee. Next, lets look at possible causes.

How Is Knee Pain On The Outside Of The Knee Diagnosed

When you see a doctor about lateral knee pain, theyll first ask you to describe the location and type of pain, for example is the pain sharp or aching? Theyll also ask you when the pain started and what activity you were doing when your symptoms began.

Theyll then perform a physical examination that will typically involve extending and flexing your knee, as well as moving it gently from side to side. This may reveal whether theres any swelling, areas of tenderness, or looseness in any of the ligaments.

Imaging tests may also be appropriate, including one or more of the following:

Based on your symptoms, the physical exam and imaging, a doctor should be able to diagnose the cause and severity of your knee injury and propose a treatment plan.

For minor lateral knee injuries, rest and conservative measures are all that are needed to allow them to heal. However, ligament tears, meniscus tears, and advanced arthritis may require surgery.

Types Of Outer Knee Pain

There are several health conditions that may cause outer knee pain.

Iliotibial band syndrome develops if a band of connective tissue rubs on the outside of your knee. The iliotibial band is a thick band of fibrous tissue that runs from your hip to below your knee on the outside of your leg. If you bend and straighten your leg a lot, it can cause this tissue to become sore and inflamed where it passes over the bottom of your thigh bone and meets your knee. This type of problem is most common in runners and cyclists.

Lateral collateral ligament injury is caused by a blow to the inside of your knee, which stretches the outside of your knee and injures the ligament. A ligament is a band of tissue that connects one bone to another. The lateral collateral ligament runs down the outer side of your knee.

Meniscal injury is damage to the meniscal cartilages inside your knee. These cartilages act like shock absorbers and may tear when you twist your knee with your foot still on the ground. This type of injury is common in sports where you have to change direction suddenly for example, football and skiing. It can also happen in jobs that involve lifting and twisting for example, construction or manual labour. The meniscus can tear without any particular injury as you get older because of wear and tear.

Symptoms Of Outer Knee Pain

The symptoms of outer knee pain will vary depending on the type of injury you have. Outer knee pain may feel dull and your knee may ache, or the pain can be sharp and limited to one area. You may have swelling from fluid that collects, or your knee may click or lock .

If you have iliotibial band syndrome, you may have pain all over the outside of your knee or the pain may be sharp and in one area. If your injury is mild, you might notice the pain come on after a certain time or distance when youre running, for example. And it may get better when you stop. If your injury is more severe, it might be painful to walk or even sit with your knee bent.

If you have a lateral collateral ligament injury, the outside of your knee will be painful. This ligament helps to keep your knee stable, so you may feel as if your knee is going to give way. You may have swelling around your knee, or pins and needles in your foot. You might find the pain is worse when you walk or run on uneven ground.

Symptoms of a torn meniscal cartilage include pain and your knee may also feel stiff, and lock or catch. There may be some swelling that may gradually get worse and you may find it difficult to fully straighten your leg. Pain can come and go, as can the swelling.

Pain from an anterior cruciate ligament injury will be sudden and you may hear a pop. Your knee is likely to swell from internal bleeding and may feel as if its going to give way.

Lateral Tibial Plateau Fracture

Prepatellar Bursitis (Anterior knee pain and swelling)

The tibial plateau is located at the top of the shin at the knee. A break on the outer or lateral part of the tibial plateau can cause considerable knee pain. A lateral tibial plateau fracture is often the result of a vehicle accident or a bad fall that impacts the outer knee directly.

If the bones are still aligned, surgery may not be required to treat the injury. If not, you may need surgery to place the affected bones in their proper position and secure them with screws or plates.

You May Have An Autoimmune Condition

In addition to rheumatoid arthritis, a number of other autoimmune conditionsin which the immune system attacks the body in various wayscan contribute to swelling and pain throughout the body, including in the knees.

Though less common, systemic autoimmune conditions, like lupus, may cause swelling, Dr. Gladstone says. Like Lyme, these conditions may explain inflammation in the knees when nothing else can. Along with pain and swelling, people with autoimmune conditions often experience chronic fatigue, muscle aches, and low fevers.

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:

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

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

When Should You Call The Doctor For A Knee Injury

Emergent medical care should be sought if, due to injury,

  • there is almost immediate swelling in the knee,
  • if the bones appear deformed,
  • if there is the inability to bear weight,
  • if the pain is intolerable,
  • if there is a loss of sensation below the injury site,
  • if the foot and ankle turn cold and no pulses can be felt.

Medical care should be considered if a knee injury does not resolve with routine home care, including rest, ice, compression, and elevation . Other symptoms that may suggest the need for medical care include recurrent pain and swelling.

A swollen joint is never normal, and if it is red and warm or if there is an associated fever, more urgent medical attention should be accessed because of the worry of infection being present. This is particularly a warning sign in infants and children, people who have had knee joint replacements, intravenous drug abusers, and those who have compromised immune systems.
