What is Knee Osteoarthritis? Causes, Symptoms, 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. Cartilage is a smooth tissue that covers the ends of bones. Because of this, your bones may rub together, causing pain and swelling. Many people call this condition “arthritis in the knee.” It can make walking or climbing stairs hard. According to the CDC, knee osteoarthritis is one of the leading causes of knee pain in adults.

Common Symptoms

People with knee osteoarthritis often notice certain signs. These symptoms can get worse over time. However, early treatment can help manage them. Common symptoms include:

Knee pain, especially after activity or at the end of the day

Stiffness in the knee joint, often in the morning or after sitting

Swelling around the knee

Cracking or popping sounds when moving the knee

Reduced movement or trouble bending the knee

Weakness in the knee or feeling like it may “give way”

Causes and Risk Factors

There are several reasons why someone might develop knee osteoarthritis. While age is a big factor, other things can increase your risk. For example, being overweight puts extra stress on your knees. In addition, past injuries or repeated stress on the knee can lead to arthritis in the knee. Here are some common causes and risk factors:

Getting older (cartilage wears down with age)

Being overweight or obese

Previous knee injuries, such as sports injuries

Family history of osteoarthritis

Jobs or activities that put stress on the knees

Diagnosis Methods

If you have knee pain or joint stiffness, a doctor can help find the cause. First, your doctor will ask about your symptoms and health history. Then, they may check your knee for swelling, tenderness, or movement problems. To confirm knee osteoarthritis, doctors often use:

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

MRI scans to see soft tissues and cartilage

Blood tests to rule out other types of arthritis

Joint fluid tests if needed

Early diagnosis can help you start the right treatment sooner.

Treatment Options

There are many ways to treat knee osteoarthritis. The goal is to reduce pain and improve movement. Your doctor may suggest one or more of these treatments:

Physical therapy to strengthen muscles around the knee

Pain relievers like acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs)

Weight loss to ease pressure on the knee

Supportive devices such as knee braces or shoe inserts

Injections, such as corticosteroids, to reduce swelling

Surgery, like knee replacement, for severe cases

For those seeking knee osteoarthritis treatment in their area, local orthopedic care centers can help.

Lifestyle Tips for Managing Knee Osteoarthritis

Although knee osteoarthritis cannot be cured, you can manage symptoms with healthy habits. For example, staying active can keep your joints flexible. Try these tips to help manage arthritis in the knee:

Use heat or cold packs to ease pain

While you cannot always prevent knee osteoarthritis, some steps can lower your risk. For instance, keeping a healthy weight reduces stress on your knees. In addition, protecting your knees from injury is important. Here are some prevention tips:

Stay active with low-impact exercises

Strengthen muscles around the knee

Use proper techniques during sports or lifting

Eat a balanced diet for joint health
