Why Do Older People Often Have Knee Pain?

Have you noticed that your elderly parent takes longer to stand up from a chair, walks more slowly than before, or complains that their knees hurt when climbing stairs? Sometimes, they may even avoid going out because walking has become uncomfortable.

Knee pain is a common problem among older adults. Some people experience pain only after walking for a long time, while others feel stiffness every morning or struggle with simple daily activities.

Although knee pain becomes more common with age, it should not automatically be dismissed as a normal part of getting older. Understanding the possible causes and knowing how to manage the pain can help your parent stay active and maintain their independence.

What Causes Knee Pain in Older Adults?

There are several possible causes of knee pain. One of the most common is osteoarthritis, but not every painful knee is caused by arthritis.

1. Osteoarthritis

Osteoarthritis happens when the protective cartilage inside a joint gradually breaks down. The knee may become painful, stiff or swollen, making it harder to walk, climb stairs or get up from a chair.

The symptoms often develop gradually. Some people notice that their knees hurt more after activity or feel stiff after sitting for a long time.

Osteoarthritis cannot currently be cured, but treatments and lifestyle changes can help manage the symptoms and improve mobility.

2. Previous Knee Injuries

An old knee injury can contribute to joint problems later in life. Previous ligament injuries, cartilage damage or surgery may increase the risk of developing knee pain as someone gets older.

If your parent has a history of knee injuries and their pain is getting worse, it is worth discussing this with a doctor.

3. Gout

Gout can cause sudden and severe joint pain due to a build-up of uric acid crystals. Although it commonly affects the big toe, it can also affect the knee.

The joint may become swollen, hot, red and extremely painful. Sudden severe knee pain should not be assumed to be gout without a proper medical assessment, because a joint infection can cause similar symptoms and requires urgent treatment.

4. Inflammation or Other Joint Conditions

Rheumatoid arthritis and other inflammatory conditions can also cause joint pain and stiffness. The pattern of symptoms may differ from osteoarthritis, so a medical assessment is important when the cause is unclear.

What Are the Signs That Knee Pain Is Affecting Your Parent’s Daily Life?

Sometimes, older adults do not directly complain about their pain. Instead, their daily habits begin to change.

You may notice that your parent:

• Uses their hands to push themselves up from a chair.

• Holds onto furniture or railings when walking.

• Avoids stairs or walks much more slowly.

• Finds it difficult to squat, bend their knees or use the toilet independently.

• Stops joining family outings because walking is uncomfortable.

• Complains of knee stiffness after waking up or sitting for a long time.

These changes may indicate that the pain is affecting their mobility and daily activities.

If knee pain continues, worsens or interferes with sleep and normal activities, arrange a medical assessment. Early evaluation can help identify the cause and determine suitable treatment.

How Can You Help an Elderly Parent with Knee Pain?

There are several ways families can support an older person experiencing knee pain. The right approach depends on the cause of the pain, the person's mobility and their overall health.

1. Encourage Gentle Movement

When your parent has knee pain, you might think that resting as much as possible is the best solution. However, avoiding movement for long periods can lead to weaker muscles and increased stiffness.

For many people with osteoarthritis, appropriate regular exercise can help reduce pain and improve muscle strength and mobility.

Depending on their ability, suitable activities may include gentle seated exercises, short walks on level ground or exercises recommended by a physiotherapist.

Start slowly and avoid forcing your parent to continue if the pain becomes significantly worse. If they have severe pain, a recent injury or difficulty bearing weight, seek medical advice before encouraging them to exercise.

2. Help Them Maintain a Healthy Weight

Excess body weight places additional stress on the knees. For an older adult who is overweight, gradual and appropriate weight management may help reduce pressure on the joints.

However, older people also need enough protein, energy and nutrients to maintain muscle strength. Avoid strict diets or rapid weight loss, especially if your parent is frail or has a poor appetite. A healthcare professional can help determine an appropriate approach.

3. Make Their Home Safer and Easier to Move Around

When knee pain makes walking difficult, everyday tasks can become challenging.

Families can make some simple changes at home:

• Keep walking paths clear of clutter.

• Ensure rooms and corridors are well lit.

• Use stable chairs with armrests to make standing easier.

• Install suitable grab bars where needed.

• Consider a walking aid if recommended by a healthcare professional.

These changes can help your parent move around more comfortably and reduce the risk of losing their balance.

4. Be Careful with Painkillers

Some people take painkillers whenever their knees hurt, but not every medication is suitable for every older adult.

Certain anti-inflammatory medicines can increase the risk of stomach bleeding, kidney problems and cardiovascular complications. These risks may be greater in people who already have kidney disease, heart disease or take blood-thinning medication.

Ask a doctor or pharmacist which treatment is appropriate for your parent. Do not start, combine or increase pain medication without checking its suitability.

5. Consider Physiotherapy

A physiotherapist can assess your parent's movement, muscle strength and mobility before recommending suitable exercises.

Depending on their condition, physiotherapy may help strengthen the muscles around the knee, improve flexibility and make daily activities easier.

The aim is not simply to reduce pain, but also to help the person move more confidently and maintain as much independence as possible.

When Should You Bring Your Parent to the Doctor?

Do not assume that every painful knee is caused by ageing or arthritis.

Seek urgent medical attention if your parent has:

• Sudden, severe knee pain.

• A very swollen or visibly deformed knee.

• A hot, red knee accompanied by fever or chills.

• An inability to move the knee or put weight on the leg, particularly after an injury.

These symptoms may indicate a serious problem that requires prompt assessment.

For less urgent symptoms, arrange an appointment if the pain keeps returning, gradually worsens or affects your parent's ability to walk, sleep or perform everyday activities.

How Can Elderly Caregivers Support Someone with Knee Pain?

For older adults who need daily assistance, knee pain can affect more than just walking. It may also make bathing, dressing, getting out of bed and using the toilet more difficult.

Caregivers can support them by allowing enough time for movement, assisting when necessary, encouraging suitable activities and observing changes in their condition.

It is also important not to force an elderly person to walk or exercise beyond their ability. The level of assistance should match their physical condition and the advice of their healthcare professionals.
