Why Is My Knee Swollen And Painful

Osteoarthritis The Most Common Reason For A Swollen Knee

Why is My Knee Swollen

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

9 Reasons Your Feet Are Swollen

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.

Can Knee Injuries Be Prevented

To help prevent knee injuries:

  • Make sure your kids wear the recommended protective equipment for sports .

  • 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.
