What is Knee Osteoarthritis?

Knee osteoarthritis is a common type of arthritis that affects the knee joint. It happens when the cartilage in your knee wears down over time. Because of this, the bones in your knee may rub against each other. This can cause pain, swelling, and stiffness. Osteoarthritis is sometimes called “wear and tear” arthritis. Although it can affect anyone, it is more common in older adults. However, younger people can get it too, especially after a knee injury.

Common Symptoms of Knee Osteoarthritis

Many people notice symptoms slowly. For example, you may feel mild pain at first. Over time, the pain may get worse. Some common knee arthritis symptoms include:

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

Difficulty bending or straightening the knee

Weakness or feeling that the knee may “give out”

Sometimes, symptoms can come and go. But as the condition progresses, they may become more constant.

Main Causes and Risk Factors

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

Previous knee injuries or surgeries

Being overweight or obese

Family history of osteoarthritis

Repeated stress on the knee from work or sports

Weak muscles around the knee

Other joint problems, such as rheumatoid arthritis

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

How is Knee Osteoarthritis Diagnosed?

If you have knee pain or stiffness, your doctor can help find the cause. Usually, diagnosis starts with a physical exam. Your doctor will check your knee for swelling, tenderness, and movement. In addition, they may ask about your symptoms and medical history. Sometimes, imaging tests like X-rays or MRI scans are needed. These tests can show changes in the joint, such as bone spurs or cartilage loss. Blood tests are not usually needed, but they may help rule out other types of arthritis.

Treatment Options for Knee Osteoarthritis

There are many osteoarthritis treatment options. The right choice depends on your symptoms and lifestyle. Some common treatments include:

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

Physical therapy: Exercises to strengthen the muscles around your knee

Weight management: Losing extra weight can reduce stress on your knee

Assistive devices: Braces or shoe inserts may help support your knee

Injections: Corticosteroid or hyaluronic acid injections for pain relief

Surgery: In severe cases, knee replacement surgery may be needed

Because everyone is different, your doctor will help you choose the best treatment plan. For those seeking knee osteoarthritis treatment in their city, local orthopedic clinics can provide care.

Prevention Tips and Lifestyle Guidance

While you cannot always prevent knee osteoarthritis, some steps may help lower your risk. For example, you can:

Maintain a healthy weight

Stay active with low-impact exercises like walking or swimming

Strengthen the muscles around your knee

Avoid activities that put too much stress on your knees

Use proper techniques when lifting or playing sports

Wear supportive shoes

Because small changes can make a big difference, try to build healthy habits into your daily routine.

When to See a Doctor
