Why Does My Knee Hurt? Common Causes of Knee Pain and When to Seek Treatment

Knee pain is one of the most common reasons people visit an orthopedic specialist. It can affect people of all ages, from athletes recovering from sports injuries to older adults dealing with arthritis, and even office workers who spend long hours sitting.

Sometimes, knee pain develops suddenly after an injury. In other cases, it appears gradually and worsens over time. While occasional discomfort may improve with rest, persistent or recurring knee pain should never be ignored.

Understanding the possible causes of knee pain can help you know when it's time to seek expert care.

Common Causes of Knee Pain

1. Osteoarthritis

Osteoarthritis is the most common cause of chronic knee pain, especially in adults over 50.

Over time, the cartilage that cushions the knee joint wears down, causing bones to rub against each other. This can result in:

• Pain while walking
• Morning stiffness
• Swelling
• Grinding or clicking sensations
• Reduced mobility

Early treatment can help manage symptoms and delay disease progression.

2. Ligament Injuries

The knee contains four major ligaments that provide stability. Sports injuries, sudden twisting movements, or accidents can cause ligament tears, particularly the ACL.

Common symptoms include:

• A popping sensation
• Immediate swelling
• Knee instability
• Difficulty walking

Prompt diagnosis is essential for proper recovery.

3. Meniscus Tears

The meniscus acts as a shock absorber inside the knee.

It can tear due to sports injuries or simply from age-related wear and tear.

Symptoms include:

• Pain while twisting
• Swelling
• Locking of the knee
• Difficulty straightening the leg

Many meniscus injuries respond well to timely treatment.

4. Runner's Knee

Despite its name, runner's knee doesn't only affect runners.

It can occur in cyclists, gym-goers, and even office workers due to muscle imbalance or poor movement patterns.

Pain is usually felt around the kneecap, especially while:

• Climbing stairs
• Squatting
• Sitting for long periods

5. Tendinitis

Overuse can inflame the tendons around the knee, causing pain during activity.

Athletes involved in jumping sports often experience patellar tendinitis, commonly known as "jumper's knee."

When Should You See an Orthopedic Specialist?

Seek medical attention if you notice:

• Pain lasting more than two weeks
• Swelling that doesn't improve
• Difficulty bearing weight
• Knee instability
• Locking or catching sensations
• Decreased range of motion

Ignoring these symptoms can allow the condition to worsen.

How Knee Pain Is Diagnosed

An orthopedic evaluation typically includes:

• Detailed medical history
• Physical examination
• X-rays
• MRI (when necessary)
• Assessment of walking pattern and joint function

An accurate diagnosis ensures the right treatment plan.

Treatment Options

Not every painful knee requires surgery.

Depending on the diagnosis, treatment may include:

• Activity modification
• Physiotherapy
• Anti-inflammatory medications
• Knee braces
• Joint injections
• Arthroscopic surgery
• Knee replacement for advanced arthritis

The goal is always to restore function while relieving pain.

Can Knee Pain Be Prevented?

Simple habits can reduce your risk:

• Maintain a healthy weight
• Strengthen leg muscles
• Stretch regularly
• Wear supportive footwear
• Avoid sudden increases in activity
• Warm up before exercise

These lifestyle changes also help protect your joints over time.
