Knee Osteoarthritis: Symptoms, Causes, Diagnosis, and Treatment

What is Knee Osteoarthritis?

Knee osteoarthritis is a common joint problem. It happens when the cartilage in your knee wears down over time. As a result, the bones in your knee may rub together. This can cause pain, swelling, and stiffness. According to the CDC, knee osteoarthritis affects millions of people worldwide. While it often develops slowly, it can make daily activities harder. Early care can help manage symptoms and improve your quality of life.

Common Symptoms of Knee Osteoarthritis

Many people notice symptoms that get worse over time. However, some may have mild signs at first. Below are common knee osteoarthritis symptoms:

Pain in the knee, especially after activity

Stiffness, often in the morning or after resting

Swelling around the knee joint

Clicking or popping sounds when moving the knee

Reduced range of motion

Feeling like the knee may “give out”

Sometimes, symptoms may come and go. But over time, they can become more frequent and severe.

Causes and Risk Factors

There are several reasons why knee osteoarthritis develops. For example, age is a major factor. As you get older, your risk increases. However, other causes and risk factors include:

Previous knee injuries

Being overweight or obese

Family history of osteoarthritis

Repeated stress on the knee from work or sports

Weak muscles around the knee

In addition, women are more likely to develop knee osteoarthritis than men. Managing these risk factors can help slow the disease.

How Knee Osteoarthritis is Diagnosed

Doctors use several steps to diagnose knee osteoarthritis. First, they ask about your symptoms and medical history. Next, they perform a physical exam. During the exam, your doctor may check for swelling, pain, and movement in your knee. In many cases, imaging tests help confirm the diagnosis. These may include:

X-rays to look for bone changes or loss of joint space

MRI scans to see cartilage and soft tissues

Sometimes, blood tests rule out other causes of knee pain. Early diagnosis can help you start treatment sooner.

Treatment Options for Knee Osteoarthritis

There are many treatment options for knee osteoarthritis. Your doctor will suggest a plan based on your needs. Some common treatments include:

Physical therapy to strengthen knee muscles

Pain relievers like acetaminophen or NSAIDs

Weight loss to reduce stress on the knee

Supportive devices, such as braces or shoe inserts

Injections, like corticosteroids, for severe pain

Surgery, such as knee replacement, for advanced cases

Most people can manage knee osteoarthritis pain with a mix of these treatments. However, surgery is usually a last resort.

Lifestyle Tips and Prevention

Simple lifestyle changes can help manage knee osteoarthritis and prevent it from getting worse. For example, you can:

Stay active with low-impact exercises like walking or swimming

Maintain a healthy weight

Use proper techniques when lifting or moving

Wear supportive shoes

Stretch and warm up before activities

In addition, eating a balanced diet supports joint health. These steps can help you stay mobile and reduce pain.
