What’s Causing My Knee Pain?

What’s Causing My Knee Pain?

Being active is one of the best things you can do for your joints and the rest of your body. But injuries can happen, and they often involve the knees.
Some of the most common problems are sprained ligaments, meniscus tears, tendinitis, and runner’s knee. If you have an old knee injury that wasn’t properly treated, it may flare up now and then or hurt all the time.

Bursitis: A bursa is a sac that holds a small amount of fluid which is under the skin above your joint. It helps prevent friction when the joint moves. Overuse, falls, or repeated bending and kneeling can irritate the bursa on top of your kneecap. That leads to pain and swelling. Doctors call this prepatellar bursitis. You may also hear it called ”preacher’s knee.”

Dislocated kneecap: This means that your kneecap slides out of position, causing knee pain and swelling. Your doctor may call this patellar dislocation.

IT (iliotibial) band syndrome: The iliotibial (IT) band is a piece of tough tissue that runs from your hip down to the outer part of your knee. When you overdo activity, it can become inflamed over time. That causes pain on the outer side of the knee. It’s common among runners when going downhill.

Meniscal tear: Sometimes, a knee injury can cause cartilage to rip. These rough edges can get stuck in the joint, which causes pain and swelling. Many times, people will have the sensation of “catching” in the joint when they are active.

Osgood-Schlatter disease: This condition happens when you’re young, when bones and other parts of the knee are still changing. It can cause a painful bump below the knee, where a tendon from the kneecap connects to the shin. Overdoing exercise, and irritation at a point on the bottom of your knee called the tibial tubercle, often make this area hurt. The ache may come and go over time. It’s especially common in teenage boys and girls.

Osteoarthritis: This is the “wear and tear” type of arthritis. It’s a top cause of knee pain after age 50. This condition causes the knee joint to ache or swell when you’re active. Joints affected by osteoarthritis can also be stiff early in the day.

Patellar tendinitis: This means you have inflammation in the tendon that connects the kneecap to the shinbone. Tendons are tough bands of tissue that connect muscles to your bones. When you overdo exercise, they can become inflamed and sore. You may also hear it called “jumper’s knee” because repetitive jumping is the most common cause.

Patellofemoral pain syndrome: Muscle imbalance, tightness, and alignment problems of the legs usually cause this condition. It causes knee pain and occasional “buckling,” meaning your knee suddenly can’t bear your weight. It’s not due to an injury. It’s more common for women than for men.
