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. Because of this, the bones in your knee may rub together. This can cause pain, swelling, and stiffness. Many people over age 50 develop knee osteoarthritis. However, it can affect younger people too. Early care can help manage symptoms and slow the disease.

Common Symptoms

Knee osteoarthritis symptoms can start slowly. Over time, they may get worse. For example, you might notice pain after walking or climbing stairs. Other signs can appear as well.

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

If you notice these symptoms, it is important to pay attention. Early treatment can help you stay active.

Causes and Risk Factors

There are several causes and risk factors for knee osteoarthritis. While aging is the most common cause, other factors can play a role. For instance, injuries or repeated stress on the knee can increase your risk.

Age over 50 years

Previous knee injury

Being overweight or obese

Family history of osteoarthritis

Jobs or sports with heavy knee use

Weak muscles around the knee

Because some risk factors can be changed, healthy habits may help lower your risk.

Diagnosis Methods

Doctors use several methods to diagnose knee osteoarthritis. First, they will ask about your symptoms and medical history. Next, they will examine your knee for swelling, pain, or movement problems. Often, imaging tests help confirm the diagnosis.

X-rays to check for bone changes

MRI scans to view soft tissues

Blood tests to rule out other causes

Joint fluid tests in some cases

With these tools, your doctor can find the best treatment for you.

Treatment Options

Treatment for knee osteoarthritis aims to reduce pain and improve movement. While there is no cure, many options can help. Your doctor may suggest a mix of treatments based on your needs.

Physical therapy to strengthen muscles

Pain relievers like acetaminophen or NSAIDs

Weight loss to reduce stress on the knee

Supportive devices such as braces or canes

Joint injections for pain relief

Surgery, such as knee replacement, for severe cases

Because each person is different, your doctor will help choose the right plan. According to the CDC, staying active is key for most people.

Lifestyle Tips and Prevention

Even though knee osteoarthritis cannot always be prevented, healthy habits can help. For example, keeping a healthy weight lowers stress on your knees. In addition, regular exercise keeps your joints flexible.

Stay active with low-impact exercises like walking or swimming

Maintain a healthy weight

Use proper techniques when lifting or playing sports

Wear supportive shoes

Stretch before and after activity

With these steps, you can manage symptoms and protect your knees.

When to See a Doctor

It is important to see a doctor if knee pain or swelling lasts more than a few days. Also, if your knee feels unstable or you cannot move it, seek help right away. Early care can prevent further damage and improve your quality of life.

Pain that does not get better with rest

Severe swelling or redness
