Osteoarthritis The Most Common Reason For A Swollen Knee
Osteoarthritis is by nature an inflammatory condition. As your arthritis worsens you may notice that the swelling is always present in the knee. Removing the fluid from an arthritic knee will usually make you feel better. Unfortunately for many arthritis sufferers, the swelling might return very rapidly.
If your knee is swelling due to Osteoarthritis, its implied that your cartilage or the cushioning within the knee joint is wearing thin. The arthritic process also changes the chemicals within the knee and creates a rather hostile environment within the knee joint. This causes the Synovium to become irritated and produce a significant amount of fluid. Occasionally that fluid will migrate to the back of the knee and cause swelling in the back of the knee. If you have a swollen area in the back of the knee it is likely a Bakers cyst.
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.
Your Knee Keeps Buckling
When you got hurt, did it feel like your knee gave way underneath you? Were not talking about a temporary sensation of weakness or some wobbliness, but more like your shin and thigh bone werent connecting or staying in place. A buckling knee could signal an ACL tear or a cruciate ligament injury.
It could start with a small pop or crack, or you could feel it after a strenuous exercise session or a soccer game.
Either way, your knee feels unstable or weak. Your knee may give out momentarily, which is scary because you might not trust yourself to walk safely when this happens. According to Dr. Howard Luks, an orthopedic surgeon, this could indicate a tear in the patella or the quadriceps tendon.
These tendons are on the front of your knees and offer a lot of support to keep you upright. If theyre not in top form, youre bound to feel weak in the knees , and you might not be able to walk at all. If this is the case, you could need surgery.
On the other hand, the weakness could be temporary, caused by wear and tear, improper footwear, or a strain. If youre a weekend warrior or youre over the age of 30 , you might experience this symptom on a regular basis.
However, if the weakness is recurring and happens every time you exercise, its possible you have a time bomb thats waiting to happen. When in doubt, seek advice from a physician.
If your knee buckles under you when you are walking, then it usually indicates instability, she says.
Acute Onset Without Injury
Rapid onset of swelling with no injury is abroad category wherein the accumulation of fluid is not due to an injury or a chronic condition, such as:
- Infection can result in joint fluid accumulation, often as a result of surgery, a knee wound, or systemic infection that spreads to the joint. Treatment can be a problem as the body has a tough time clearing infection from this space. Surgery may be required to fully clean out a .
- Gout and pseudogout involve a buildup of crystals in the knee fluid. With gout, the uric acid used to transport waste can accumulate and crystallize in various joints of the body, causing intense swelling and pain. With pseudogout, the culprit is calcium crystals.
Pain Swelling And Knee Stiffness
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.

- Make sure your kids wear the recommended protective equipment for sports .
- Make sure your kids wear supportive athletic shoes that are in good condition.
- During workouts, kids should always warm up and cool down.
- Encourage kids to do regular strength training to support muscles, and stretching or yoga to improve flexibility.
- When jumping, kids should bend the knees while landing. This takes pressure off the ACL and prevents injury.
- If kids cut laterally or pivot frequently , encourage them to crouch and bend at the knees and hips to reduce the chances of an ACL injury.
- For kids who play just one sport, conditioning and training year-round even if it’s at a lower intensity than during the competitive season can help them stay in shape and make an injury less likely.
Bursitis Could Be To Blame
Often confused with arthritis, bursitis is another condition that can cause swollen knees. Bursitis is a reaction in which sacks of fluids, blood vessels, and nerve endings that cushion your jointscalled bursaebecome inflamed, explains Dr. Gladstone. Typically, bursitis occurs across the front of the knees as a result of excess pressure and friction on the joint over time.
Those little blood vessels bleed and the bursa produces excess fluid, which creates this giant, swollen pouchlike a bubble of fluid just below the skin, Dr. Gladstone says. These inflamed pouches, which can take on all sorts of shapes and sizes, can be incredibly painful to put pressure on.
Bursitis is most common in people who work a lot on their knees, like carpenters, plumbers, and tile-setters, says Dr. Gladstone. However, a good fall can cause bursitis, too.

We dont fully understand how Lyme works, but it can manifest in many different ways, including joint swelling, he explains. According to the Centers for Disease Control and Prevention , the knees are particularly susceptible to severe Lyme-related arthritis, pain, and swelling.
Its worth noting, though, that these symptoms show up as the disease advances . Earlier signs of Lyme disease include the telltale bullseye-shaped rash and flu-like symptoms, such as fatigue, fever, headaches, muscle pain, and neck stiffness. Given Lymes murky mechanisms, treatment is relatively straightforward and involves a course of antibiotics to wipe the bacteria out of the body.

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.
Rapid Knee Swelling Without An Injury
Occasionally, a swollen knee develops rapidly without any injury. The most common causes of this are:
1. Infection: Infections increase in the amount of fluid produced in the joint resulting in a swollen knee. Knee infections usually develop after surgery or a deep cut, but sometimes an infection in your body can spread to your joint.
It is very difficult for your body to fight an infection within a joint and sometimes surgery is required before the swelling will go down.
2. Gout Knee: High levels of uric acid cause sharp, needle like crystals to form in your joints leading to inflammation and water on the knee.
Gout is usually treated with medication and appropriate diet. Find out more about the causes, symptoms and treatment options in the Gout Knee section.
