Do Symptoms Start In A Smaller Joint
Many autoimmune conditions, including rheumatoid and psoriatic arthritis, cause initial symptoms in smaller joints before impacting the knee.
Lupus arthritis also does not typically start in the knee. Early symptoms can affect the fingers, wrists, elbows, ankles, and toes.
However, gout, infectious and reactive arthritis, post-traumatic injury, and lupus tend to impact the knee early on.
The following types of arthritis might affect the knee.
OA happens when joint cartilage degrades with age and wear and tear of joints, decreasing the cushioning space between the bones and producing painful growths called bone spurs.
Osteoarthritis can affect any joint in the body and more than one at a time.
Post-traumatic arthritis occurs after injury to the knee. Post-traumatic arthritis can affect the ligaments and cartilage that stabilize and support the joint.
Gout occurs when uric acid crystals deposit in joints, fluids, and tissues. Gout may also impact the ankles or feet.

How Is It Treated
Some kids who have JIA might take medicine like ibuprofen to help control pain and inflammation. If the arthritis is more severe, they may need to take other medicines to help lower the pain and inflammation. Some of these medicines are pills, but others are shots.
It’s important that kids with JIA keep their joints moving. Often a kid will see a physical therapist or occupational therapist. In addition to working with children to move their joints and strengthen their muscles, these therapists can help create special exercise programs for home or school that can help a kid stay active.
In addition to joint problems, JIA may cause uveitis , an inflammation of the eye that can lead to problems with vision if it’s not treated. All kids diagnosed with JIA should get their eyes checked by an ophthalmologist, a doctor who specializes in diagnosing and treating eye problems. If the eyes are affected, they may be treated with eye drops.
Besides taking medicines, a kid can do a few things to help with the symptoms of JIA:
- Keep joints warm and stay active.
- Take warm baths, which can make a kid’s joints hurt less.
- Use an electric blanket on a timer that turns on 1 hour before a kid wakes up, which can help warm the joints and help a kid move better.
- Some kids dip their hands in a special warm wax called paraffin that helps their joints ache less.
Why Do Kids Get It
No one really knows what causes JIA. Something in the environment, like a virus, may trigger the disease in kids that already have certain genes that make it more likely for them to get it.
JIA is not contagious, so you can’t catch it from someone else.
Arthritis is an autoimmune disease. An autoimmune disease means a person’s immune system makes a mistake and attacks the body’s own tissues or organs. Normally, a kid’s immune system sends out white blood cells to protect the body and fight outside invaders like bacteria and viruses that can make a kid sick. But with an autoimmune disease like JIA, the immune system makes a mistake and attacks healthy cells.
Instead of recognizing the healthy cells and saying, “Hi, nice to see you,” the immune system thinks the healthy cells need to be destroyed and releases chemicals to fight the healthy cells. The chemicals released by the immune system cause the pain and swelling that can happen with arthritis.

Potential Causes Of Knee Swelling
Whether water on the knee is mildly annoying or painfully debilitating, a person will want to identify the likely cause and treat the symptoms to help reduce the likelihood of future problems. Chronic or long-standing swelling may lead to joint tissue damage, cartilage degradation, and bone softening, therefore treatment is usually recommended.
This article describes 12 conditions that frequently cause knee swelling, also called water on the knee.
1. Injury to the kneeTrauma to the knee’s bones, ligaments, tendons, bursae, meniscus, or articular cartilage can cause pain and swelling. Serious injury can cause blood to flood into the knee joint, leading to significant swelling, warmth, stiffness, and bruising. This condition is called hemarthrosis and warrants urgent medical care.
A patient should also seek medical attention if knee pain is severe, if the affected leg cannot bear weight, or if there is suspicion of a broken bone.
2. Knee osteoarthritisDegeneration of the cartilage of the knee joint can result in an overproduction of joint fluid, causing the knee to swell. A swollen knee due to knee osteoarthritis is typically accompanied by pain.
In fact, evidence suggests people who have severe knee pain from osteoarthritis are more likely to experience knee swelling. One study2 found that:
People should seek medical attention immediately if they think their symptoms may be caused by septic bursitis.

Complications Of A Swollen Knee
You may develop a Baker’s cyst. This is when joint fluid leaks out into the back of the knee and causes pain and swelling. Treatment usually involves compression and applying ice packs. However, if your swelling is severe, you may need to have the fluid removed using a fine needle.
You may lose muscle mass, especially in your thigh muscles. This is because fluid in your swollen knee can prevent your thigh muscles from working properly over time this causes them to weaken and deteriorate.

When To Contact A Doctor
Below are guidelines to help people decide if their knee swelling requires medical attention. If the person is still unsure whether to seek professional medical treatment, a phone call to a doctor or nurse can help determine whether an office visit is necessary.
A doctor should be contacted if:
- The knee is severely swollen or has a pronounced abnormality
- The knee cannot fully straighten or fully bend
- The knee is severely painful
- The person cannot bear weight on the knee, or feels as if the knee is going to “give out”
- The skin over the knee turns hot or red
- The person has a fever of 100.4° F or higher
- Knee swelling has been present for 3 days or longer
A doctor will examine the patient’s knee and ask the patient several questions. The physical examination and patient interview may provide enough information to make an accurate diagnosis. If more information is needed, the doctor may recommend medical imaging, such as an x-ray, or removing fluid from the knee using an in-office procedure called aspiration.
Seek immediate care if the leg swelling occurs suddenly with no known reason, particularly if it is accompanied by symptoms such as leg pain, chest pain, and/or problems breathing, as these may be signs of a life-threatening blood clot.
Exercise And Other Knee Arthritis Remedies
For both OA and inflammatory knee arthritis patients, exercise is a key component of treatment, particularly if youre overweight or obese
Physical therapy may be a necessary first step for some to strengthen the muscles surrounding your knee joint and improve range of motion. Low-impact exercises walking, cycling, or swimming are usually best for those with arthritis of the knee, but you may be able to do higher-impact exercises if dont have much joint damage.
To help make activity more comfortable, your doctor may recommend using assistive devices such as a cane or a knee brace or sleeve. Wearing well-cushioned, shock-absorbing shoes or inserts is also key unsupportive styles such as flip-flops and flimsy flats only exacerbate knee joint pain. High heels, which throw off your alignment and place added stress on your knees, should also be avoided.
Its also a good idea to talk to your doctor about how to get more rest, since many people with arthritis experience sleep disturbances that studies suggest can lead to pain, depression, and greater disability. Simply practicing good sleep hygiene sticking to a regular bedtime, keeping your bedroom quiet and dark, exercising during the day, etc. can help in many cases.

What Can Cause Swelling Above Knee
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.
Frequently Asked Questions About Knee Arthritis
Why does my knee click or pop?
Knees can make noise from time to time, especially knees with osteoarthritis. This can be from a variety of causes, most of which are not cause for alarm. In knees with osteoarthritis, the smooth cartilage surface on the end of the bone wears down and becomes damaged, making the ends of the bones uneven and rough. When the knee bends and straightens, these rough surfaces move past each other and can make a clicking or snapping sound. Osteoarthritis can also cause the lining of the knee joint to become thickened and inflamed. This is called synovitis. Sometimes clicking or snapping can be caused by this thickened synovium rubbing over the edges of the bones and knee cap. Concerning symptoms would be popping that leads to a significant amount of painful swelling or instances where the knee locks up and cannot be bent or straightened. These symptoms should be evaluated by your doctor.

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.

Is Surgery Used To Treat Knee Osteoarthritis
If your doctor wants to treat the osteoarthritis in the knee with surgery, the options are arthroscopy, osteotomy, and arthroplasty.
- Arthroscopy uses a small telescope and other small instruments. The surgery is performed through small incisions. The surgeon uses the arthroscope to see into the joint space. Once there, the surgeon can remove damaged cartilage or loose particles, clean the bone surface, and repair other types of tissue if those damages are discovered. The procedure is often used on younger patients in order to delay more serious surgery.
- An osteotomy is a procedure that aims to make the knee alignment better by changing the shape of the bones. This type of surgery may be recommended if you have damage primarily in one area of the knee. It might also be recommended if you have broken your knee and it has not healed well. An osteotomy is not permanent, and further surgery may be necessary later on.
- Joint replacement surgery, or arthroplasty, is a surgical procedure in which joints are replaced with artificial parts made from metals or plastic. The replacement could involve one side of the knee or the entire knee. Joint replacement surgery is usually reserved for people over age 50 with severe osteoarthritis. The surgery may need to be repeated later if the prosthetic joint wears out after several years. But with today’s modern advancements, most new joints will last over 20 years. The surgery has risks, but the results are generally very good.

Gradual Knee Swelling Without An Injury
A swollen knee that develops gradually is usual a sign of an underlying knee condition rather than an injury. The fluid on the knee tends to come and go and varies in amount. There is usually only mild to moderate amounts of swelling in these cases.
Arthritisis the most common cause of gradual knee swelling, often referred to as water on the knee. Arthritis is the wear and tear of the cartilage and bones. It causes the body to produce extra fluid in the knee, which fluctuates in amounts. Other symptoms of arthritis include stiffness and crepitus .
Sometimes if the leg has been overworked, or gets knocked or twisted, the joint gets irritated and responds by producing more fluid to try and protect and heal itself, hence the term water on the knee.

Factors That Can Worsen Knee Osteoarthritis
When you live with osteoarthritis the most common type of arthritis knee pain and stiffness can seem difficult to avoid. Your knees and other joints may feel swollen, especially after being active, and the symptoms can worsen over time. More than just wear and tear on your joints, osteoarthritis is a joint disease.
Some of the factors that can worsen knee osteoarthritis pain wont come as a surprise. For example, if youve had a long career working at a job that requires you to stand for extended periods of time, bend a lot, or lift heavy objects, this can impact your cartilage, or the connective tissue in the joints between bones. When cartilage wears away, this causes swelling, pain, and trouble moving the knee joint. Athletes who sustained injuries, even long ago, can also be at risk for faster cartilage breakdown and osteoarthritis.
As osteoarthritis progresses, the knee and other bones may break down and develop what are called spurs, which are growths around the bones edges. Little pieces of bone or cartilage can also break off and float around in the knee joint, according to the Arthritis Foundation. In the later stage of osteoarthritis, the cartilage between the knee bones wears away completely, causing bone to rub against bone, which can lead to even more pain as well as joint damage.
