What Is Knee Osteoarthritis?

Knee osteoarthritis is a common joint problem that affects many adults. It happens when the cartilage in your knee wears down over time. Because of this, the bones in your knee may rub together. This can cause pain, swelling, and stiffness. Many people look for knee pain treatment to help manage these symptoms. According to the CDC, knee osteoarthritis is one of the leading causes of disability in older adults.

Common Symptoms of Knee Osteoarthritis

People with knee osteoarthritis often notice changes in their knees. For example, you may feel pain when walking or climbing stairs. Over time, the symptoms can get worse. However, early treatment can help manage knee arthritis and improve your quality of life. Watch for these signs:

Pain in the knee, especially after activity

Stiffness, often in the morning or after sitting

Swelling around the knee joint

Clicking or popping sounds when moving the knee

Reduced range of motion

Weakness or feeling that the knee may give way

Causes and Risk Factors

Many things can lead to knee osteoarthritis. Age is a major factor, but it is not the only one. For instance, injuries or repeated stress on the knee can also play a role. Knowing the causes can help you take steps to protect your joints. Here are some common causes and risk factors:

X-rays to look for joint damage or bone changes

MRI scans for a detailed view of soft tissues

Blood tests to rule out other causes of joint pain

Joint fluid tests to check for infection or gout
