Knee pain is a common issue for people of all ages. Various factors, including injury, arthritis or overuse, can cause it. While some knee pain can be treated at home with rest and over-the-counter pain medication, other types of pain require medical attention. Below are six common causes of knee pain and when you should see a doctor.

Common Causes of Knee Pain


Osteoarthritis is a leading cause of knee pain in people over 50. It occurs when the knee joint cartilage begins to wear down, leading to pain, stiffness and swelling.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune and inflammatory disorder that can affect the knee joint. It causes the lining of the joint to become inflamed, leading to pain, stiffness and swelling.

Meniscus Tear

A meniscus tear is a painful knee injury that occurs when the knee is twisted or bent forcefully. It can cause discomfort, swelling and difficulty moving the knee.

Ligament Injury

Ligament injuries, such as a torn ACL or MCL, can cause severe knee pain and instability. These injuries often occur during sports or other physical activities.

Patellofemoral Pain Syndrome

Patellofemoral pain syndrome, also called runner’s knee, is a common condition that causes pain around the kneecap. It can be caused by injury, overuse or kneecap misalignment.


Bursitis occurs when the tiny fluid-filled sacs around the knee joint become inflamed. It can cause pain and swelling around the knee.
