How to prevent knee pain sitting at a desk

Knee problems from simply sitting for long periods at a desk have become prevalent in today's modern work environment.

This type of knee discomfort, called desk-related knee pain, can significantly impact an individual's overall well-being and productivity.

Taking proactive steps to address and prevent it in the workplace benefits individuals and promotes a healthier and more productive work environment.

In this article, we will examine the source of knee pain when sitting at a desk, discuss conservative measures and ergonomic adjustments, and more!

Causes of Knee Pain When Sitting at a Desk

Causes of knee pain

So, why does your knee hurt? The femur (thigh bone) has a groove where your patella (knee cap) rests. Different portions of the kneecap lightly touch the femur when you sit.

If certain places are sensitive to contact, you can experience knee pain when sitting or getting up from an office chair. It can be your body's natural response to an unnatural situation.

Let's delve into the various factors contributing to knee pain when sitting at a desk, ranging from poor office ergonomics and wrong position, to lack of movement and muscle imbalances.

GOOD TO KNOW: According to Harvard Medical School, sitting more than 6 to 8 hours daily may harm your health. They recommend avoiding sitting for extended periods, but if you must, get around and stretch your knees every half hour to 60 minutes.

Incorrect Posture

When we sit with incorrect posture, we compromise the natural alignment of our spine and put undue stress on various parts of our bodies, including the knees.

The following are some common postural mistakes that can contribute to the pain:

  • Slouching
  • Legs crossed
  • Sitting too low or too high
  • Forward head posture
  • Unsupported feet

Prolonged Sitting Periods

In today's predominantly desk-bound work culture, prolonged sitting has become a common part of many individuals' daily routines.

While sitting itself may seem relatively passive, the lack of movement and the static nature of sitting can harm the knees.

Addressing knee pain resulting from long periods of sitting requires proactive measures to counteract the negative effects of sitting.

Arthritis-Related Knee Pain

When sitting at a desk, arthritis, specifically osteoarthritis, is a typical source of knee pain.

Osteoarthritis is a degenerative joint ailment that breaks the cartilage beneath the joints, particularly the knees.

While aging is a primary risk factor for osteoarthritis, desk-related factors can contribute to developing and worsening arthritis-related knee pain.

Patellofemoral Pain Syndrome

Sitting at a desk might aggravate patellofemoral pain syndrome (PFPS), often known as a runner's knee.

It is a medical condition indicated by pain around or behind the patella (kneecap) and is often aggravated by activities that involve bending the knees, including sitting for extended periods.

Managing the pain caused by PFPS (runner's knee) when sitting at a desk involves implementing certain strategies.

GOOD TO KNOW: Housemaid's knee, also known as prepatellar bursitis or knee bursitis, is characterized by the swelling of the bursa in front of the kneecap (patella). The term originated because this condition was common among housemaids who spent long hours kneeling while performing their duties.

Poorly Designed Desk Chairs

Understanding the causes of poorly designed desk chairs can help individuals make informed choices to prevent or alleviate the pain:

  • Lack of adjustable features
  • Insufficient lumbar aid
  • Inadequate cushioning and padding
  • The chair's armrests are not adjustable
  • Improper seat depth
  • Lack of swivel or mobility

Can a bad chair cause knee pain?

Unsuitable office chairs can be a cause for nagging knee pain. Pain issues may arise from an improper desk chair or an inability to adjust the chair height correctly. Therefore, selecting suitable, adjustable chairs for optimal support is critical for maintaining joint health and preventing knee pain.

Rheumatoid arthritis often presents with symptoms of fatigue, generalized malaise, and feeling unwell. Watch for signs of affected joints, particularly in the knees.

Reducing the Impact on Gout Pain

If you have gout and your knee hurts, it is crucial to prevent the aggravation of gout pain and minimize the impact on other conditions.

Follow your healthcare provider's medication regimen for managing gout. Make dietary adjustments to reduce the risk of gout attacks.

Maintain a healthy weight or attain a healthy weight range. Stay well-hydrated by drinking adequate water throughout the day.

Frequently Asked Questions

We have compiled these topics to address the frequently asked questions surrounding this issue to provide valuable insights and guidance.

How Can a Bad Desk Chair Contribute to Knee Pain?

Too-tall or too-short workspaces force your body into an awkward position as you work, which is bad for all the joints in your body.

Your knees will be constantly bent when you sit in a chair that is too low, which might result in knee pain and joint issues.

Which Exercises Are Most Effective to Relieve Knee Pain While Sitting at a Desk?

The Knee Full Extension Exercise is one of the most effective exercises to relieve knee pains.

Sit on a comfortable chair high enough for the knees to bend to a 90-degree angle first. Lift the other leg gradually until it is horizontal.

Hold for five seconds, then let it slowly lower it again. Continue with the opposite leg.

What Is a Proper Sitting Position to Avoid Knee Pain?

Sitting with your feet flat on the floor and your back straight is the proper ergonomic sitting position to avoid knee pain.

How Often Should I Take Standing and Stretching Breaks When Sitting for Long Periods?

Avoid sitting down for prolonged periods; try to stand up at least once every 20 to 30 minutes. Never sit for more than 10 minutes after two hours.

Can Using a Footrest Help Alleviate Knee Pain While Sitting at a Table for Extended Periods?

Yes. Footrests help straighten posture, lessen fatigue, and lessen pain or discomfort in the thighs, feet, ankles, and knees.

Are Recliners Good for Your Knees?

While reclining chairs may provide momentary comfort, prolonged use can lead to problems in the musculature and joint health. Over time, chronic use of a recliner can induce hip and knee contractures, leading to tight muscles over your joints. This, in turn, can result in adverse postural changes, thereby impairing upright posture and standing.


To summarize, the pain experienced while sitting at a desk for an extended period can be attributed to various factors, including incorrect posture, awkward position, etc.

People can relieve knee pain and promote long-term health by prioritizing proper ergonomics, incorporating regular breaks and rehab exercises, and addressing underlying conditions.

Remember, maintaining healthy and pain-free knees is essential for a comfortable seating position and overall well-being and productivity in daily life.
