Knee Pain: Causes, Treatments & When to See a Doctor

What Is Knee Pain?

Knee pain is a widespread complaint that can affect people of all ages. It may result from an injury, such as a torn ligament or cartilage, or from medical conditions like arthritis or gout. Many types of knee pain respond well to self-care and physical therapy.

Common Causes of Knee Pain

• Osteoarthritis or rheumatoid arthritis
• ACL or meniscus tears
• Tendinitis (overuse)
• Bursitis
• Runner's knee (patellofemoral syndrome)
• Obesity placing extra stress on joints

When to See a Doctor

See a doctor if your knee is swollen, can't bear weight, feels unstable or locks up, or if the pain is severe or doesn't improve after a week of home care. Sudden knee injuries with a popping sound warrant prompt evaluation.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

What causes knee pain without injury?

Knee pain without injury is often caused by arthritis, overuse, or aging. Conditions like osteoarthritis gradually wear down cartilage, leading to pain and stiffness that develops over time.

Is walking good for knee pain?

Gentle walking can actually help knee pain by keeping joints lubricated and muscles strong. However, if walking makes the pain worse, rest and consult a doctor before continuing.

When does knee pain need surgery?

Surgery is typically considered when conservative treatments fail after several months. Torn ligaments, severe arthritis, or loose cartilage may require surgical intervention.

What doctor should I see for knee pain?

Start with your primary care doctor or see an orthopedic specialist directly. For sports-related injuries, a sports medicine doctor is ideal. Physical therapists can also evaluate and treat many knee conditions.

An orthopedic consultation typically costs $200-$500 without insurance. X-rays or MRIs may cost extra. OpenMyPro helps you find affordable orthopedic care near you.
