What Are Some Common Causes of Knee Pain?

Knee pain is one of the most common reasons people visit an orthopaedic doctor . Because your knees are responsible for so much movement and are under so much pressure each day, they are particularly prone to painful injuries that can cause both acute and chronic discomfort. Although many different things can cause knee pain, here is a look at some of the most common causes.

Meniscal Tears

In some cases, a piece of cartilage in the knee—called the meniscus—will tear as the result of an injury. Part of the meniscus can then get caught between the joints in the knee and cause pain. Meniscal tears often happen when your feet are planted but you quickly turn your knee, such as when you’re lifting something heavy or while you’re playing a sport. If this occurs, in addition to knee pain, you may feel like your knee isn’t stable or that your joint is catching when you move.


Osteoarthritis occurs are the result of wear and tear on the joints in the knee. It is most common in people over 50, although obesity can cause it to appear earlier in life. With osteoarthritis, the knee may swell and become painful with activity. Stiffness may also occur. Weight loss can dramatically improve the symptoms of osteoarthritis. In some cases, your orthopaedic doctor may recommend a knee replacement surgery if the pain doesn’t respond to less invasive treatments.


Between your skin and your knee joint is a bursa, a fluid-filled sac that prevents you from feeling friction on your skin when your joint moves. Sometimes, the bursa becomes inflamed, causing bursitis. Falling can trigger bursitis, as can joint overuse. Bending at the knee and kneeling frequently are common triggers of this painful condition. If you have bursitis, you may be unable to put pressure on your knee when you kneel, and it may swell with activity.
