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

The most common causes of knee pain are related to aging, injury or repeated stress on the knee.
Common knee problems include sprained or strained ligaments, cartilage tears, tendonitis and arthritis.
Diagnosing a knee injury or problem includes a medical examination and usually the use of a diagnostic procedure such as an x-ray, MRI, CT scan or arthroscopy.
Both non-operative and surgical treatment options are available to treat knee pain and problems depending on the type and severity of the condition.

There Are Many Possible Causes Of Knee Pain Radiating Down Shin:

The knee joint can become inflamed and inflamed arthritis, which can lead to stiffness and pain. Sometimes the pain can be debilitating and lasting for a long time. Arthritis in the knee usually results from wear and tear, osteoarthritis but other forms of arthritis can affect the knee joint, such as blood pressure and gout uric acid crystal buildup, and pseudo-gout calcium crystal buildup. Severe complications that cause joint knee pain may include fractures and infections septic arthritis.

Myofascial pain occurs due to stress with the surrounding muscles, ligaments and tendons of the knee. Muscles can develop small thin knots taut bands that are called interesting myo-fascial markers. Stimulant components are unsightly spots in the fascia covering that surrounds the muscles and can be very painful and completely debilitating. When a touch cell is touched or examined, it can cause severe pain in and around the area.

Injury of the frontal ligament ACL can be demolished by sports such as football, basketball and skiing.

Meniscus The meniscus is a hard, soft cartilage that acts as a knee joint. It is similar to a record within the spine. The meniscus can break in some cases as with a sudden knee.

Patellar Tendonitis pain in the patella tendon can occur when the kneecap tendon is swollen and swollen. Sometimes the patella may disintegrate.

What Is The Long

Some knee pain, especially pain caused by osteoarthritis, will likely be permanent. Thats because the structure of the knee is damaged. Without surgery or another type of extensive treatment, youll continue to feel pain, inflammation, and swelling in your knee.

The long-term outlook for chronic knee pain involves managing pain, preventing flare-ups, and working to reduce irritation to the knee.

The treatment for conditions that cause swelling, redness, and dull, burning pain usually starts with resting the joint. Ice your knee to control swelling. Elevate and stay off your joint to promote healing.

Your doctor may recommend or prescribe NSAIDs like ibuprofen. Lifestyle changes, such as wearing protective kneepads and going to physical therapy, can help you manage pain and experience fewer symptoms.

You may need to make changes to your diet, especially if youre treating gout.

Diagnosis And Treatment Of A Swollen Knee

When a person is experiencing a swollen knee, the doctor may either take a sample of the fluid inside the knee, or order X-rays or an MRI to confirm a diagnosis. If its a minor injury, the medical provider may recommend rest, icing, compression, and elevation of the knee .

Depending on the severity, the doctor may also recommend medication, steroid injections, or physical therapy. In extreme cases, a patient may require surgery.

What Are The Causes Of Knee Pain In Teenagers

Common knee pain problems in your teenager can be generally divided into three types:

Anterior knee pain, also called patellofemoral pain.
Injures to ligaments and tendons of the knee or to the kneecap itself.
Medical conditions that affect the knee.

Anterior knee pain happens when your teens kneecap is pulled out of its groove from increased pressure. Increased pressure on the knee joint is caused by:

Abnormal hip rotation due to imbalances in muscle strength and flexibility around the hips.
Improper training methods or equipment.
Poor flexibility of the thigh muscles, which support the knee joint. Thigh muscle weakness or tightness.
Overuse of the knee from repetitive bending of the knee during running, jumping, and other activities.
Problems with alignment, for example, the kneecap not being properly aligned within the knee or having flat feet, which changes the normal gait.

Knee pain resulting from sprains, strains and tears to ligaments and tendons or injuries to other soft tissues. These conditions include:

Medical conditions that can affect your teens knee include:

What Else Could It Be

There are a number of other conditions that can cause pain behind the knee without typically causing much, if any, back of knee swelling visit the back of knee pain section to find out loads more.

Alternatively, it may be that there is swelling all around the knee, not just at the back, in which case, visit the swollen knee section.

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.

How Are Knee Problems Diagnosed

Knee Swelling – Adam V. Metzler, M.D.

In addition to a complete medical history and physical exam, other tests for knee problems may include:

X-ray. This test uses invisible electromagnetic energy beams to make images of internal tissues, bones, and organs onto film.
Magnetic resonance imaging . This test uses large magnets, radiofrequencies, and a computer to make detailed images of organs and structures within the body can often determine damage or disease in a surrounding ligament or muscle.
Computed tomography scan . This test uses X-rays and computer technology to make horizontal, or axial, images of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
Arthroscopy. A minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube , which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen used to evaluate any degenerative or arthritic changes in the joint to detect bone diseases and tumors to determine the cause of bone pain and inflammation.
Radionuclide bone scan. A nuclear imaging technique that uses a very small amount of radioactive material, which is injected into the patient’s bloodstream to be detected by a scanner. This test shows blood flow to the bone and cell activity within the bone.

Complementary And Alternative Therapies

A number of mind-body therapies, such as acupuncture and tai chi, may be used to treat knee pain, especially knee osteoarthritis.

While once popular, the dietary supplements glucosamine and chondroitin have fallen out of favor for treating knee osteoarthritis. This is due to their lack of benefit based on scientific studies although, some people may obtain mild relief. Like any medication, vitamin, or supplement, be sure to talk with your doctor first before taking it to be certain it is safe for you.

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.

Can A Bulging Disc Cause Knee Pain

Because your lower spine carries a significant amount of weight and is constantly in motion, your spinal discs are vulnerable to injury and pain.

Injuries to your disc can cause the soft inner core to migrate from its normal position and push against the fibrous outer layers . Alternatively, the fibrous rings can be torn, allowing the soft material to leak out.

A disc is typically found close to the spinal cord and spinal nerve roots .

A Herniated disc can affect many nerve roots, including the sciatic nerve. Once the sciatic nerve is affected, knee pain is highly possible.

For Ligament Cartilage And Joint Tears

Ligament, cartilage and joint tears in your knee will need to be addressed by your doctor.

After imaging diagnostics and a clinical assessment, your doctor will let you know if your treatment will include physical therapy and anti-inflammatory medication, or if youll need to undergo surgery to repair the injury.

Recovery from knee surgery can take some time. It may take anywhere from 6 months to a year to resume your normal activities.

If You Feel Pain Behind Your Knee When Bending Or Squatting:

You may be feeling a symptom of Patellar Tendonitis . This is caused by repetitive activity like kicking, jumping or running. The repetitive exercise puts a lot of strain on the tendon resulting in tiny tears and inflammation along the patellar tendon. Other symptoms include pain just below the kneecap, pain with any pressure to the knee, aching and stiffness after activity, knee stiffness in the morning and thickening of the patellar tendon.

What Causes Chronic Knee Pain

Temporary knee pain is different from chronic knee pain. Many people experience temporary knee pain as a result of an injury or accident. Chronic knee pain rarely goes away without treatment, and it isnt always attributable to one incident. Its most often the result of several causes or conditions.

Physical conditions or diseases can cause knee pain. These include:

osteoarthritis: pain, inflammation, and joint destruction caused by degeneration and deterioration of the joint
tendinitis: pain in the front of the knee that is made worse when climbing, taking stairs, or walking up an incline
bursitis: inflammation caused by repeated overuse or injury of the knee
gout: arthritis caused by the buildup of uric acid
Bakers cyst: a buildup of synovial fluid behind the knee
rheumatoid arthritis : a chronic autoimmune inflammatory disorder that causes painful swelling and can eventually cause joint deformity and bone erosion
dislocation: dislocation of the kneecap most often the result of trauma
meniscus tear: a rupture in one or more of the cartilage in the knee
torn ligament: tear in one of the four ligaments in the knee the most commonly injured ligament is the anterior cruciate ligament
bone tumors: osteosarcoma , most commonly occurs in the knee

Factors that may make chronic knee pain worse:

injuries to the structure of the knee can cause bleeding and swelling and can create a chronic problem over time if not treated properly

Osteoarthritis And Rheumatoid Arthritis

Osteoarthritis and rheumatoid arthritis are two common types of arthritis that can lead to knee tightness. Osteoarthritis causes the cartilage in the knee to erode, leading to malalignment. Rheumatoid arthritis causes damage to the lining of the joints, which leads to inflammation. Both types of arthritis can lead to limited function and range of motion, deformity, and tightness.

Exercises that strengthen the surrounding muscle groups may help your range of motion and knee stability.

What Can Cause Swelling Above Knee

Common Causes of Knee Pain

Swelling above knee appears like a puffed knee and the accumulation of fluid may give it a bulging appearance.2 Swelling above knee or swollen knee is often accompanied with pain, discomfort and inability to move the knee joint properly. The knee may appear red, warm to touch and weight bearing on the knee, walking and other activities may be difficult. Complete bending or straightening of the knee may be difficult and painful on account of swelling above knee.

There can be many causes for swelling above knee, which includes:

Swelling above Knee Caused Due to Injury or Trauma: Any injury or direct trauma to the soft tissue surrounding knee joint can result in swelling above the knee. People engaged in sports, adventure games, or an accident can experience swelling above the knee joint due to injuries to soft tissues resulting in ligament strains, tendon injuries, muscle strains, cartilage and meniscus injuries. Injuries to the knee cap and soft tissues of the knee cap can cause swelling above the knee. Serious injuries like fractures or dislocations of knee cap and knee joint too can cause swelling above the knee joint because of collection of blood. If the pain is very severe with inability to move the knee, then immediate medical attention should be sought.

Problems In The Patella

Other common causes of knee pain are the problems in the patella, such as the patellar condropathy, which is the wear of the joint around the patella or the patellar condromalacia, which is the softening of the cartilage of the patella. Generally, the causes of the problems on the patella are aging, obesity, boring foot or sports like running, for example.

The lesions on the patella can cause knee pain when squat or knee pain when going down stairs, plus feeling that the knee is coming out of place.

What to do: for jogging practitioners, the counselor is to switch from sport temporarily to swimming or hydrogymnastics until having the musculature of the knee strengthened. Physiotherapy can help in the strengthening of the knee and after pain relief, physical educator-oriented musculation can be done. In addition, the doctor can make injection of hyaluronic acid in the knee and, in the most severe cases, surgery can be recommended.

Delayed Knee Swelling After An Injury

If a swollen knee develops anything from a few hours to a few days after an injury, it is most likely due to an increase in the synovial fluid in the joint a knee effusion.

This happens when something inside the knee is damaged slightly causing irritation and a resultant increase in synovial fluid. The amount of swelling varies but it tends not to be as much as with a haemarthrosis and the swollen knee doesnt usually feel tense.

The most common causes of a knee joint effusion are:

1. Meniscus Irritation: Compression or a small tear in the outer part of the cartilage lining the joint – the inner part of the meniscus has a poor blood supply so doesnt tend to bleed much when damaged.

2. Knee Sprain:Where one of the knee ligaments is overstretched, damaging a few fibres, but the ligament remains intact.

The amount of knee swelling may vary day to day and it may feel like it comes and goes as the injury is healing. It usually takes 6-12 weeks for soft tissues to heal, but cartilage injuries can take longer, as the cartilage has a very poor blood supply.

Visit the Knee Injuries section to find out more about these common causes of fluid on the knee, including symptoms and treatment options.

Use Your Knee Brace And Crutches

If youve been fitted for a knee brace or had one recommended to you, make sure it fits properly. You should be able to insert two fingers under the strap. If its difficult to fit two fingers or if you can fit a third finger, youll need to adjust the tightness. Usually youll wear the brace for two to six weeks.

Use crutches if theyve been given and avoid putting any pressure on your knee until your doctor says its okay. Wait at least two weeks or until your doctor gives you the go-ahead before you bathe, swim, or use a hot tub. Follow a healthy diet and drink plenty of fluids. Eat high-fiber foods such as fresh fruits and vegetables to ensure you have regular bowel movements. This will help while you may not have the benefit of moving around as much as usual.

What Are The Symptoms Of Sciatica In The Knee

The most bothersome symptom is dorsiflexion or weakness that prevents your foot from lifting towards your leg. You walk with a dragged foot as a result.

You can also experience pain outside your lower leg and on the top of your foot if you have a pinched peroneal nerve.

Nerve pain, tingling sensations, or pins and needles are some of the common symptoms. A person may also feel numbness, pain, and a burning sensation.

In the case of a pinched nerve that has been present for two weeks or longer, the muscles supplied by the nerve can begin to waste away.

Whats pushing on the nerve may cause intermittent or continuous symptoms.

In addition, pinched nerves in the lower back can cause these symptoms. It is also possible to have pain in your lower back or hip and outside your leg if this is the cause.
