What About Sleeping?

This is where the social-media caption associated with images like this can become misleading.

Sleeping itself does not normally cause advanced knee osteoarthritis.

However, an uncomfortable knee can certainly interfere with sleep.

People with chronic knee pain may have difficulty finding a comfortable position, may wake when they turn over, or may experience increased awareness of pain at night.

Some people find that placing a pillow between or underneath the legs makes certain sleeping positions more comfortable.

The appropriate position depends on the individual's symptoms, other medical conditions, and personal comfort.

Why Does Knee Damage Develop?

There isn't always one single cause.

Risk factors for knee osteoarthritis and other degenerative joint problems can include:

• Increasing age
• Previous knee injuries
• Repeated joint stress
• Excess body weight
• Muscle weakness
• Certain joint abnormalities
• Family history
• Some inflammatory or metabolic conditions

Importantly, developing knee pain does not mean that someone has done something wrong.

Joint problems can develop even in people who exercise regularly and maintain a healthy lifestyle.

Can Knee Damage Be Prevented?

There is no guaranteed way to prevent every knee problem, but several habits can support joint health.

Maintaining a healthy body weight can reduce mechanical stress on weight-bearing joints.

Regular physical activity can also help strengthen the muscles around the knee.

Low-impact activities such as walking, swimming, cycling, and appropriately designed strength exercises can be useful for many people.

After a knee injury, appropriate rehabilitation is also important.
